136-558: Xcode is Apple 's integrated development environment (IDE) for macOS , used to develop software for macOS, iOS , iPadOS , watchOS , tvOS , and visionOS . It was initially released in late 2003; the latest stable release is version 16, released on September 16, 2024, and is available free of charge via the Mac App Store and the Apple Developer website. Registered developers can also download preview releases and prior versions of

272-451: A boardroom coup and called an emergency meeting at which Apple's executive staff sided with Sculley and stripped Jobs of all operational duties. Jobs resigned from Apple in September 1985 and took several Apple employees with him to found NeXT . Wozniak had also quit his active employment at Apple earlier in 1985 to pursue other ventures, expressing his frustration with Apple's treatment of

408-611: A multi-touch iPod Nano , an iPod Touch with FaceTime , and an iPod Shuffle that brought back the clickwheel buttons of earlier generations. It also introduced the smaller, cheaper second-generation Apple TV which allowed the rental of movies and shows. On January 17, 2011, Jobs announced in an internal Apple memo that he would take another medical leave of absence for an indefinite period to allow him to focus on his health. Chief operating officer Tim Cook assumed Jobs's day-to-day operations at Apple, although Jobs would still remain "involved in major strategic decisions". Apple became

544-515: A read-eval-print loop (or REPL) is useful for learning, experimenting and fast prototyping. Playgrounds was used by Apple to publish Swift tutorials and guided tours where the REPL advantages are noticeable . The Playgrounds feature was developed by the Developer Tools department at Apple. According to Chris Lattner , the inventor of Swift Programming Language and Senior Director and Architect at

680-526: A $ 309 million profit. On May 6, 1998, Apple introduced a new all-in-one computer reminiscent of the original Macintosh: the iMac . The iMac was a huge success, with 800,000 units sold in its first five months, and ushered in major shifts in the industry by abandoning legacy technologies like the 3 + 1 ⁄ 2 -inch diskette , being an early adopter of the USB connector, and coming pre-installed with Internet connectivity (the "i" in iMac) via Ethernet and

816-470: A GUI and some level of a CLI, although the GUIs usually receive more attention. GUI wrappers find a way around the command-line interface versions (CLI) of (typically) Linux and Unix-like software applications and their text-based UIs or typed command labels. While command-line or text-based applications allow users to run a program non-interactively, GUI wrappers atop them avoid the steep learning curve of

952-401: A US jury ruled that Samsung should pay Apple $ 1.05 billion (£665m) in damages in an intellectual property lawsuit. Samsung appealed the damages award, which was reduced by $ 450 million and further granted Samsung's request for a new trial. On November 10, 2012, Apple confirmed a global settlement that dismissed all existing lawsuits between Apple and HTC up to that date, in favor of

1088-410: A combination of technologies and devices to provide a platform that users can interact with, for the tasks of gathering and producing information. A series of elements conforming a visual language have evolved to represent information stored in computers. This makes it easier for people with few computer skills to work with and use computer software. The most common combination of such elements in GUIs

1224-477: A decade. In the 1990s, Apple lost considerable market share in the personal computer industry to the lower-priced Wintel duopoly of the Microsoft Windows operating system on Intel -powered PC clones . In 1997, Apple was weeks away from bankruptcy . To resolve its failed operating system strategy, it bought NeXT, effectively bringing Jobs back to the company, who guided Apple back to profitability over

1360-403: A dial-up modem. Its striking teardrop shape and translucent materials were designed by Jonathan Ive , who had been hired by Amelio, and who collaborated with Jobs for more than a decade to reshape Apple's product design. A little more than a year later on July 21, 1999, Apple introduced the iBook consumer laptop. It culminated Jobs's strategy to produce only four products: refined versions of

1496-433: A distraction not only for me and my family, but everyone else at Apple as well", and explained that the break would allow the company "to focus on delivering extraordinary products". Though Jobs was absent, Apple recorded its best non-holiday quarter (Q1 FY 2009) during the recession , with revenue of $ 8.16 billion and profit of $ 1.21 billion. After years of speculation and multiple rumored "leaks", Apple unveiled

1632-505: A grid of items with rows of text extending sideways from the icon. Multi-row and multi-column layouts commonly found on the web are "shelf" and "waterfall". The former is found on image search engines , where images appear with a fixed height but variable length, and is typically implemented with the CSS property and parameter display: inline-block; . A waterfall layout found on Imgur and TweetDeck with fixed width but variable height per item

1768-444: A large screen, tablet-like media device known as the iPad on January 27, 2010. The iPad ran the same touch-based operating system as the iPhone, and all iPhone apps were compatible with the iPad. This gave the iPad a large app catalog on launch, though having very little development time before the release. Later that year on April 3, 2010, the iPad was launched in the U.S. It sold more than 300,000 units on its first day, and 500,000 by

1904-582: A month later, Xcode 4.5.2 was released, with support for iPad Mini and iPad with Retina Display, and bug fixes and stability improvements. On January 28, 2013, iOS 6.1 and Xcode 4.6 were released. On June 10, 2013, at the Apple Worldwide Developers Conference , version 5 of Xcode was announced. On September 18, 2013, Xcode 5.0 was released. It shipped with iOS 7 and OS X 10.8 Mountain Lion SDKs. However, support for OS X 10.9 Mavericks

2040-576: A more modern approach. This led to the Pink project in 1988, A/UX that same year, Copland in 1994, and evaluated the purchase of BeOS in 1996. Talks with Be stalled when the CEO, former Apple executive Jean-Louis Gassée , demanded $ 300 million in contrast to Apple's $ 125 million offer. Only weeks away from bankruptcy , Apple's board preferred NeXTSTEP and purchased NeXT in late 1996 for $ 400 million, retaining Steve Jobs . The NeXT acquisition

2176-558: A new step-by-step execution feature introduced in Xcode 10 at WWDC 2018 . Formerly, Xcode supported distributing a product build process over multiple systems. One technology involved was named Shared Workgroup Build , which used the Bonjour protocol to automatically discover systems providing compiler services, and a modified version of the free software product distcc to facilitate the distribution of workloads. Earlier versions of Xcode provided

2312-463: A paid account, 3.2.6 is the latest download that appears for Snow Leopard. Xcode 4.3, released on February 16, 2012, is distributed as one application bundle, Xcode.app, installed from the Mac App Store. Xcode 4.3 reorganizes the Xcode menu to include development tools. Xcode 4.3.1 was released on March 7, 2012 to add support for iOS 5.1. Xcode 4.3.2 was released on March 22, 2012 with enhancements to

2448-790: A power struggle between Steve Jobs and CEO John Sculley , who had been hired away from Pepsi two years earlier by Jobs saying, "Do you want to sell sugar water for the rest of your life or come with me and change the world?" Sculley removed Jobs as the head of the Macintosh division, with unanimous support from the Apple board of directors. The board of directors instructed Sculley to contain Jobs and his ability to launch expensive forays into untested products. Rather than submit to Sculley's direction, Jobs attempted to oust him from leadership. Jean-Louis Gassée informed Sculley that Jobs had been attempting to organize

2584-502: A preferential rate. This visit influenced Jobs to implement a GUI in Apple's products, starting with the Apple Lisa . Despite being pioneering as a mass-marketed GUI computer, the Lisa suffered from high costs and limited software options, leading to commercial failure. Jobs, angered by being pushed off the Lisa team, took over the company's Macintosh division. Wozniak and Raskin had envisioned

2720-506: A program was busy. Additionally, it was the first GUI to introduce something resembling Virtual Desktops . Windows 95 , accompanied by an extensive marketing campaign, was a major success in the marketplace at launch and shortly became the most popular desktop operating system. In 2007, with the iPhone and later in 2010 with the introduction of the iPad , Apple popularized the post-WIMP style of interaction for multi-touch screens, and those devices were considered to be milestones in

2856-474: A retail store, airline self-ticket and check-in, information kiosks in a public space, like a train station or a museum, and monitors or control screens in an embedded industrial application which employ a real-time operating system (RTOS). Cell phones and handheld game systems also employ application specific touchscreen GUIs. Newer automobiles use GUIs in their navigation systems and multimedia centers, or navigation multimedia center combinations. A GUI uses

2992-414: A short sequence of words and symbols. Custom functions may be used to facilitate access to frequent actions. Command-line interfaces are more lightweight , as they only recall information necessary for a task; for example, no preview thumbnails or graphical rendering of web pages. This allows greater efficiency and productivity once many commands are learned. But reaching this level takes some time because

3128-564: A single application to users and letting the operating system automatically choose the appropriate architecture at runtime. Using the iOS SDK , tvOS SDK, and watchOS SDK, Xcode can also be used to compile and debug applications for iOS , iPadOS , tvOS , and watchOS . Xcode includes the GUI tool Instruments , which runs atop a dynamic tracing framework, DTrace , created by Sun Microsystems and released as part of OpenSolaris . Xcode also integrates built-in support for source code management using

3264-444: A source code file with quick navigation. Xcode 11 requires macOS 10.14 or later and Xcode 11.4 requires 10.15 or later. Xcode 11 was publicly released on September 20, 2019. On June 22, 2020, at the Apple Worldwide Developers Conference , Xcode version 12 was announced; a beta version was released the same day. Xcode 12 introduced support for Swift 5.3 and requires macOS 10.15.4 or later. Xcode 12 dropped building apps for iOS 8 and

3400-473: A system named Dedicated Network Builds . These features are absent in the supported versions of Xcode. Xcode also includes Apple's WebObjects tools and frameworks for building Java web applications and web services (formerly sold as a separate product). As of Xcode 3.0, Apple dropped WebObjects development inside Xcode; WOLips should be used instead. Xcode 3 still includes the WebObjects frameworks. Xcode 1.0

3536-428: A system or moved about to different places during redesigns. Also, icons and dialog boxes are usually harder for users to script. WIMPs extensively use modes , as the meaning of all keys and clicks on specific positions on the screen are redefined all the time. Command-line interfaces use modes only in limited forms, such as for current directory and environment variables . Most modern operating systems provide both

3672-599: A ten-year license agreement for current and future patents between the two companies. It is predicted that Apple will make US$ 280   million per year from this deal with HTC. In May 2014, Apple confirmed its intent to acquire Dr. Dre and Jimmy Iovine 's audio company Beats Electronics —producer of the "Beats by Dr. Dre" line of headphones and speaker products, and operator of the music streaming service Beats Music —for US$ 3   billion, and to sell their products through Apple's retail outlets and resellers. Iovine believed that Beats had always "belonged" with Apple, as

3808-608: A variety of programming models, including but not limited to Cocoa , Carbon , and Java. Third parties have added support for GNU Pascal , Free Pascal , Ada , C# , Go , Perl , and D . Xcode can build fat binary ( universal binary ) files containing code for multiple architectures with the Mach-O executable format. These helped ease the transitions from 32-bit PowerPC to 64-bit PowerPC, from PowerPC to Intel x86 , from 32-bit to 64-bit Intel, and most recently from Intel x86 to Apple silicon by allowing developers to distribute

3944-664: Is a related technology that promises to deliver the representation benefits of 3D environments without their usability drawbacks of orientation problems and hidden objects. In 2006, Hillcrest Labs introduced the first ZUI for television. Other innovations include the menus on the PlayStation 2 , the menus on the Xbox , Sun's Project Looking Glass , Metisse , which was similar to Project Looking Glass, BumpTop , where users can manipulate documents and windows with realistic movement and physics as if they were physical documents, Croquet OS , which

4080-525: Is based on NeXTSTEP , OpenStep , and BSD Unix , to combine the stability, reliability, and security of Unix with the ease of use of an overhauled user interface. Second, in May 2001, the first two Apple Store retail locations opened in Virginia and California, offering an improved presentation of the company's products. At the time, many speculated that the stores would fail, but they became highly successful, and

4216-531: Is best known for its consumer electronics , software , and services . Founded in 1976 as Apple Computer Company by Steve Jobs , Steve Wozniak and Ronald Wayne , the company was incorporated by Jobs and Wozniak as Apple Computer, Inc. the following year. It was renamed Apple Inc. in 2007 as the company had expanded its focus from computers to consumer electronics. Apple is the largest technology company by revenue , with US$ 391.04   billion in FY 2024. The company

4352-417: Is especially common with applications designed for Unix-like operating systems. The latter used to be implemented first because it allowed the developers to focus exclusively on their product's functionality without bothering about interface details such as designing icons and placing buttons. Designing programs this way also allows users to run the program in a shell script . Many environments and games use

4488-655: Is represented by rotating a cube with faces representing each user's workspace, and window management is represented via a Rolodex -style flipping mechanism in Windows Vista (see Windows Flip 3D ). In both cases, the operating system transforms windows on-the-fly while continuing to update the content of those windows. The GUI is usually WIMP-based, although occasionally other metaphors surface, such as those used in Microsoft Bob , 3dwm, File System Navigator, File System Visualizer , 3D Mailbox, and GopherVR . Zooming (ZUI)

4624-426: Is still possible to target older versions, and the simulator supports iPhone OS 2.0 through 3.1. Also, Java support is "exiled" in 3.2 to the organizer. Xcode 3.2.6 is the last version that can be downloaded for free for users of Mac OS X Snow Leopard (though it’s not the last version that supports Snow Leopard; 4.2 is). Downloading Xcode 3.2.6 requires a free registration at Apple's developer site. In June 2010, at

4760-440: Is the windows, icons, text fields, canvases, menus, pointer ( WIMP ) paradigm, especially in personal computers . The WIMP style of interaction uses a virtual input device to represent the position of a pointing device's interface , most often a mouse , and presents information organized in windows and represented with icons . Available commands are compiled together in menus, and actions are performed making gestures with

4896-427: Is then limited to creating x86 and x86-64 binaries. Later, Xcode was free to the general public. Before version 4.1, Xcode cost $ 4.99. Xcode 4.1 was made available for free on July 20, 2011 (the day of Mac OS X Lion 's release) to all users of Mac OS X Lion on the Mac App Store. On August 29, 2011, Xcode 4.1 was made available for Mac OS X Snow Leopard for members of the paid Mac or iOS developer programs. Xcode 4.1

5032-551: Is usually implemented by specifying column-width: . Smaller app mobile devices such as personal digital assistants (PDAs) and smartphones typically use the WIMP elements with different unifying metaphors, due to constraints in space and available input devices. Applications for which WIMP is not well suited may use newer interaction techniques , collectively termed post-WIMP UIs. As of 2011, some touchscreen-based operating systems such as Apple's iOS ( iPhone ) and Android use

5168-398: Is valued at just over $ 3.2 trillion. Apple has received criticism regarding its contractors ' labor practices, its relationship with trade unions , its environmental practices , and its business ethics, including anti-competitive practices and materials sourcing. Nevertheless, the company has a large following and enjoys a high level of brand loyalty . Apple Computer Company

5304-582: The Apple II series was discontinued. It was expensive to produce, and the company decided it was still absorbing sales from lower-cost Macintosh models. After the launch of the LC, Apple encouraged developers to create applications for Macintosh rather than Apple II, and authorized salespersons to redirect consumers from Apple II and toward Macintosh. The Apple IIe was discontinued in 1993. Apple experimented with several other unsuccessful consumer targeted products during

5440-517: The Apple Worldwide Developers Conference version 4 of Xcode was announced during the Developer Tools State of the Union address. Version 4 of the developer tools consolidates the Xcode editing tools and Interface Builder into one application, among other enhancements.

5848-506: The Macworld Expo on January 9, 2007, Jobs announced the renaming of Apple Computer, Inc. to Apple Inc., because the company had broadened its focus from computers to consumer electronics. This event also saw the announcement of the iPhone and the Apple TV . The company sold 270,000 first-generation iPhones during the first 30 hours of sales, and the device was called "a game changer for

5984-527: The Power Macintosh , the first of many computers with Motorola's PowerPC processor. In the wake of the alliance, Apple opened up to the idea of allowing Motorola and other companies to build Macintosh clones . Over the next two years, 75 distinct Macintosh clone models were introduced. However, by 1996, Apple executives were worried that the clones were cannibalizing sales of its own high-end computers, where profit margins were highest. In 1996, Spindler

6120-518: The Power Macintosh G3 desktop and PowerBook G3 laptop for professionals, and the iMac desktop and iBook laptop for consumers. Jobs said the small product line allowed for a greater focus on quality and innovation. Around then, Apple also completed numerous acquisitions to create a portfolio of digital media production software for both professionals and consumers. Apple acquired Macromedia 's Key Grip digital video editing software project which

6256-475: The SoundJam MP audio player software from Casady & Greene . Apple renamed the program iTunes , and simplified the user interface and added CD burning. In 2001, Apple changed course with three announcements. First, on March 24, 2001, Apple announced the release of a new modern operating system, Mac OS X . This was after numerous failed attempts in the early 1990s, and several years of development. Mac OS X

6392-501: The Swift programming language. The original version of the feature was announced and released by Apple Inc on June 2, 2014, during WWDC 2014 . Playgrounds provide a testing ground that renders developer code in real time. They have the capability of evaluating and displaying the results of single expressions as they are coded (in line or on a side bar), providing rapid feedback to the programmer. This type of development environment, known as

6528-512: The TRS-80 and Commodore PET , because of its character cell-based color graphics and open architecture . The Apple I and early Apple II models use ordinary audio cassette tapes as storage devices, which were superseded by the 5 + 1 ⁄ 4 -inch floppy disk drive and interface called the Disk II in 1978. The Apple II was chosen to be the desktop platform for the first killer application of

6664-629: The Xerox Star . These early systems spurred many other GUI efforts, including Lisp machines by Symbolics and other manufacturers, the Apple Lisa (which presented the concept of menu bar and window controls ) in 1983, the Apple Macintosh 128K in 1984, and the Atari ST with Digital Research 's GEM , and Commodore Amiga in 1985. Visi On was released in 1983 for the IBM PC compatible computers, but

6800-628: The chief operating officer . Gassée left the company later that year to set up a rival, Be Inc. The company pivoted strategy and, in October 1990, introduced three lower-cost models: the Macintosh Classic , the Macintosh LC , and the Macintosh IIsi , all of which generated significant sales due to pent-up demand. In 1991, Apple introduced the hugely successful PowerBook with a design that set

6936-550: The command line . The main application of the suite is the integrated development environment (IDE), also named Xcode. The Xcode suite includes most of Apple's developer documentation, and built-in Interface Builder , an application used to construct graphical user interfaces . Up to Xcode 4.1, the Xcode suite included a modified version of the GNU Compiler Collection . In Xcode 3.1 up to Xcode 4.6.3, it included

7072-452: The cursor (or rather pointer ) control: mouse , pointing stick , touchpad , trackball , joystick , virtual keyboards , and head-up displays (translucent information devices at the eye level). There are also actions performed by programs that affect the GUI. For example, there are components like inotify or D-Bus to facilitate communication between computer programs. Ivan Sutherland developed Sketchpad in 1963, widely held as

7208-523: The iLife suite. At the Worldwide Developers Conference keynote address on June 6, 2005, Jobs announced that Apple would move away from PowerPC processors, and the Mac would transition to Intel processors in 2006. On January 10, 2006, the new MacBook Pro and iMac became the first Apple computers to use Intel's Core Duo CPU. By August 7, 2006, Apple made the transition to Intel chips for

7344-401: The third- and fourth-generation iPads , which featured Retina displays ; and the iPad Mini , which featured a 7.9-inch screen in contrast to the iPad's 9.7-inch screen. These launches were successful, with the iPhone 5 (released September 21, 2012) becoming Apple's biggest iPhone launch with over two million pre-orders and sales of three million iPads in three days following the launch of

7480-470: The $ 99 per year Mac Developer program and the $ 99 per year iOS Developer program. It was also sold for $ 4.99 to non-members on the Mac App Store (no longer available). Xcode 4.0 drops support for many older systems, including all PowerPC development and software development kits (SDKs) for Mac OS X 10.4 and 10.5, and all iOS SDKs older than 4.3. The deployment target can still be set to produce binaries for those older platforms, but for Mac OS platforms, one

7616-616: The 1970s, Engelbart's ideas were further refined and extended to graphics by researchers at Xerox PARC and specifically Alan Kay , who went beyond text-based hyperlinks and used a GUI as the main interface for the Smalltalk programming language , which ran on the Xerox Alto computer , released in 1973. Most modern general-purpose GUIs are derived from this system. The Xerox PARC GUI consisted of graphical elements such as windows , menus , radio buttons , and check boxes . The concept of icons

7752-547: The 1990s, including QuickTake digital cameras , PowerCD portable CD audio players, speakers , the Pippin video game console, the eWorld online service, and Apple Interactive Television Box . Enormous resources were invested in the problematic Newton tablet division, based on John Sculley's unrealistic market forecasts. Throughout this period, Microsoft continued to gain market share with Windows by focusing on delivering software to inexpensive personal computers, while Apple

7888-530: The App Store could become a billion-dollar business for Apple. By October 2008, Apple was the third-largest mobile handset supplier in the world due to the popularity of the iPhone. On January 14, 2009, Jobs announced in an internal memo that he would be taking a six-month medical leave of absence from Apple until the end of June 2009 and would spend the time focusing on his health. In the email, Jobs stated that "the curiosity over my personal health continues to be

8024-522: The Apple II division and stating that the company had "been going in the wrong direction for the last five years". Wozniak remained employed by Apple as a representative, receiving a stipend estimated to be $ 120,000 per year. Jobs and Wozniak remained Apple shareholders following their departures. After the departures of Jobs and Wozniak in 1985, Sculley launched the Macintosh 512K that year with quadruple

8160-472: The Apple Reference Library tool, which allows searching and reading online documentation from Apple's website and documentation installed on a local computer. Xcode 2.1 could create universal binary files. It supported shared precompiled headers , unit testing targets, conditional breakpoints, and watchpoints. It also had better dependency analysis. The final version of Xcode for Mac OS X v10.4

8296-695: The Developer Tools Department, Playgrounds was "heavily influenced by Bret Victor's ideas, by Light Table and by many other interactive systems". Playgrounds was announced by Apple Inc. on June 2, 2014, during WWDC 2014 as part of Xcode 6 and released in September. In September 2016, the Swift Playgrounds application for iPad (also available on macOS starting in February 2020) was released, incorporating these ideas into an educational tool. Xcode's Playgrounds feature continued development, with

8432-506: The GUIs advantages, many reviewers questioned the value of the entire concept, citing hardware limits, and problems in finding compatible software. In 1984, Apple released a television commercial which introduced the Apple Macintosh during the telecast of Super Bowl XVIII by CBS , with allusions to George Orwell 's noted novel Nineteen Eighty-Four . The goal of the commercial was to make people think about computers, identifying

8568-608: The LLVM-GCC compiler, with front ends from the GNU Compiler Collection and a code generator based on LLVM . In Xcode 3.2 and later, it included the Clang C/C++/Objective-C compiler, with newly-written front ends and a code generator based on LLVM, and the Clang static analyzer . Starting with Xcode 4.2, the Clang compiler became the default compiler, Starting with Xcode 5.0, Clang was the only compiler provided. Up to Xcode 4.6.3,

8704-421: The Macintosh as a low-cost computer with a text-based interface like the Apple II, but a plane crash in 1981 forced Wozniak to step back from the project. Jobs quickly redefined the Macintosh as a graphical system that would be cheaper than the Lisa, undercutting his former division. Jobs was also hostile to the Apple II division, which at the time, generated most of the company's revenue. In 1984, Apple launched

8840-583: The Macintosh, the first personal computer without a bundled programming language . Its debut was signified by " 1984 ", a US$ 1.5   million television advertisement directed by Ridley Scott that aired during the third quarter of Super Bowl XVIII on January 22, 1984. This was hailed as a watershed event for Apple's success and was called a "masterpiece" by CNN and one of the greatest TV advertisements of all time by TV Guide . The advertisement created great interest in Macintosh , and sales were initially good, but began to taper off dramatically after

8976-637: The RAM, and introduced the LaserWriter , the first reasonably priced PostScript laser printer . PageMaker , an early desktop publishing application taking advantage of the PostScript language, was also released by Aldus Corporation in July 1985. It has been suggested that the combination of Macintosh, LaserWriter, and PageMaker was responsible for the creation of the desktop publishing market. This dominant position in

9112-546: The Xcode suite used the GNU Debugger (GDB) as the back-end for the IDE's debugger . Starting with Xcode 4.3, the LLDB debugger was also provided; starting with Xcode 4.5 LLDB replaced GDB as the default back-end for the IDE's debugger. Starting with Xcode 5.0, GDB was no longer supplied. The Playgrounds feature of Xcode provides an environment for rapid experimentation and development in

9248-490: The app interface, and support for Xcode Cloud, Apple’s newly-launched mobile CI/CD service (it also has a web version). Xcode 13 was publicly released on September 20, 2021.

Xcode 14 dropped support for building apps for iOS 9 and 10 (these versions of iOS supported 32-bit iOS apps) and

9384-582: The business world: VisiCalc , a spreadsheet program released in 1979. VisiCalc created a business market for the Apple II and gave home users an additional reason to buy an Apple II: compatibility with the office, but Apple II market share remained behind home computers made by competitors such as Atari , Commodore , and Tandy . On December 12, 1980, Apple (ticker symbol "AAPL") went public selling 4.6 million shares at $ 22 per share ($ .10 per share when adjusting for stock splits as of September 3, 2022 ), generating over $ 100 million, which

These support styles of interaction using more than one finger in contact with a display, which allows actions such as pinching and rotating, which are unsupported by one pointer and mouse. Human interface devices , for the efficient interaction with a GUI include a computer keyboard , especially used together with keyboard shortcuts , pointing devices for

9656-457: The command words may not be easily discoverable or mnemonic . Also, using the command line can become slow and error-prone when users must enter long commands comprising many parameters or several different filenames at once. However, windows, icons, menus, pointer ( WIMP ) interfaces present users with many widgets that represent and can trigger some of the system's available commands. GUIs can be made quite hard when dialogs are buried deep in

9792-413: The command-line, which requires commands to be typed on the keyboard . By starting a GUI wrapper, users can intuitively interact with, start, stop, and change its working parameters, through graphical icons and visual indicators of a desktop environment , for example. Applications may also provide both interfaces, and when they do the GUI is usually a WIMP wrapper around the command-line version. This

9928-732: The company modeled itself after Apple's "unmatched ability to marry culture and technology". The acquisition was the largest purchase in Apple's history. Graphical user interface The actions in a GUI are usually performed through direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones and smaller household, office and industrial controls . The term GUI tends not to be applied to other lower- display resolution types of interfaces , such as video games (where head-up displays ( HUDs ) are preferred), or not including flat screens like volumetric displays because

10064-671: The core of its computer offerings. The next month, in August 1997, Steve Jobs convinced Microsoft to make a $ 150 million investment in Apple and a commitment to continue developing Mac software. This was seen as an "antitrust insurance policy" for Microsoft which had recently settled with the Department of Justice over anti-competitive practices in the United States v. Microsoft Corp. case. Around then, Jobs donated Apple's internal library and archives to Stanford University , to focus more on

10200-428: The current shape for almost all modern laptops. The same year, Apple introduced System 7 , a major upgrade to the Macintosh operating system, adding color to the interface and introducing new networking capabilities. The success of the lower-cost Macs and PowerBook brought increasing revenue. For some time, Apple was doing very well, introducing fresh new products at increasing profits. The magazine MacAddict named

10336-571: The designer's work to change the interface as user needs evolve. Good GUI design relates to users more, and to system architecture less. Large widgets, such as windows , usually provide a frame or container for the main presentation content such as a web page, email message, or drawing. Smaller ones usually act as a user-input tool. A GUI may be designed for the requirements of a vertical market as application-specific GUIs. Examples include automated teller machines (ATM), point of sale (POS) touchscreens at restaurants, self-service checkouts used in

10472-402: The desktop publishing market allowed the company to focus on higher price points, the so-called "high-right policy" named for the position on a chart of price vs. profits. Newer models selling at higher price points offered higher profit margin , and appeared to have no effect on total sales as power users snapped up every increase in speed. Although some worried about pricing themselves out of

10608-500: The desktop publishing market and estranged many of its original consumer customer base who could no longer afford Apple products. The Christmas season of 1989 was the first in the company's history to have declining sales, which led to a 20% drop in Apple's stock price. During this period, the relationship between Sculley and Gassée deteriorated, leading Sculley to effectively demote Gassée in January 1990 by appointing Michael Spindler as

10744-485: The development of mobile devices . The GUIs familiar to most people as of the mid-late 2010s are Microsoft Windows , macOS , and the X Window System interfaces for desktop and laptop computers, and Android , Apple's iOS , Symbian , BlackBerry OS , Windows Phone / Windows 10 Mobile , Tizen , WebOS , and Firefox OS for handheld ( smartphone ) devices. Since the commands available in command line interfaces can be many, complex operations can be performed using

10880-435: The display represents a desktop, on which documents and folders of documents can be placed. Window managers and other software combine to simulate the desktop environment with varying degrees of realism. Entries may appear in a list to make space for text and details, or in a grid for compactness and larger icons with little space underneath for text. Variations in between exist, such as a list with multiple columns of items and

11016-404: The end of the first week. In May 2010, Apple's market cap exceeded that of competitor Microsoft for the first time since 1989. In June 2010, Apple released the iPhone 4 , which introduced video calling using FaceTime , multitasking , and a new design with an exposed stainless steel frame as the phone's antenna system. Later that year, Apple again refreshed the iPod line by introducing

11152-509: The entire Mac product line—over one year sooner than announced. The Power Mac, iBook, and PowerBook brands were retired during the transition; the Mac Pro , MacBook , and MacBook Pro became their respective successors. Apple also introduced Boot Camp in 2006 to help users install Windows XP or Windows Vista on their Intel Macs alongside Mac OS X. Apple's success during this period was evident in its stock price . Between early 2003 and 2006,

11288-593: The first graphical computer-aided design program. It used a light pen to create and manipulate objects in engineering drawings in realtime with coordinated graphics. In the late 1960s, researchers at the Stanford Research Institute , led by Douglas Engelbart , developed the On-Line System (NLS), which used text-based hyperlinks manipulated with a then-new device: the mouse . (A 1968 demonstration of NLS became known as " The Mother of All Demos ".) In

11424-504: The first of more than 500 stores around the world. Third, on October 23, 2001, the iPod portable digital audio player debuted. The product was first sold on November 10, 2001, and was extremely successful, with over 100 million units sold within six years. In 2003, the iTunes Store was introduced with music downloads for 99¢ a song and iPod integration. It quickly became the market leader in online music services, with over 5 billion downloads by June 19, 2008. Two years later,

11560-470: The first prototype Apple I at the Homebrew Computer Club in July 1976. The Apple I was sold as a motherboard with CPU , RAM , and basic textual-video chips—a base kit concept which was not yet marketed as a complete personal computer. It was priced soon after debut for $ 666.66 (equivalent to $ 3,600 in 2023). Wozniak later said he was unaware of the coincidental mark of the beast in

11696-399: The first three months as reviews started to come in. Jobs had required 128 kilobytes of RAM, which limited its speed and software in favor of aspiring for a projected price point of $ 1,000 (equivalent to $ 2,900 in 2023). The Macintosh shipped for $ 2,495 (equivalent to $ 7,300 in 2023), a price panned by critics due to its slow performance. In early 1985, this sales slump triggered

11832-825: The iOS Simulator and a suggested move to the LLDB debugger versus the GDB debugger (which appear to be undocumented changes). Xcode 4.3.3, released in May 2012, featured an updated SDK for Mac OS X 10.7.4 "Lion" and a few bug fixes. Xcode 4.4 was released on July 25, 2012. It runs on both Mac OS X Lion (10.7) and OS X Mountain Lion (10.8) and is the first version of Xcode to contain the OS X 10.8 "Mountain Lion" SDK. Xcode 4.4 includes support for automatic synthesizing of declared properties, new Objective-C features such as literal syntax and subscripting, improved localization, and more. On August 7, 2012, Xcode 4.4.1

11968-458: The iPad Mini and fourth-generation iPad (released November 3, 2012). Apple also released a third-generation 13-inch MacBook Pro with a Retina display and new iMac and Mac Mini computers. On August 20, 2012, Apple's rising stock price increased the company's market capitalization to a then-record $ 624 billion. This beat the non-inflation-adjusted record for market capitalization previously set by Microsoft in 1999. On August 24, 2012,

12104-465: The iTunes Store was the world's largest music retailer. In 2002, Apple purchased Nothing Real for its advanced digital compositing application Shake , and Emagic for the music productivity application Logic . The purchase of Emagic made Apple the first computer manufacturer to own a music software company. The acquisition was followed by the development of Apple's consumer-level GarageBand application. The release of iPhoto that year completed

12240-557: The iTunes Store, effective in May 2007. Other record labels eventually followed suit and Apple published a press release in January 2009 to announce that all songs on the iTunes Store are available without their FairPlay DRM. In July 2008, Apple launched the App Store to sell third-party applications for the iPhone and iPod Touch . Within a month, the store sold 60 million applications and registered an average daily revenue of $ 1 million, with Jobs speculating in August 2008 that

12376-432: The incorporation of Apple. During the first five years of operations, revenues grew exponentially, doubling about every four months. Between September 1977 and September 1980, yearly sales grew from $ 775,000 to US$ 118   million, an average annual growth rate of 533%. The Apple II , also designed by Wozniak, was introduced on April 16, 1977, at the first West Coast Computer Faire . It differs from its major rivals,

12512-408: The industry". In an article posted on Apple's website on February 6, 2007, Jobs wrote that Apple would be willing to sell music on the iTunes Store without digital rights management , thereby allowing tracks to be played on third-party players if record labels would agree to drop the technology. On April 2, 2007, Apple and EMI jointly announced the removal of DRM technology from EMI's catalog in

12648-485: The interface found in current versions of Microsoft Windows, and in various desktop environments for Unix-like operating systems , such as macOS and Linux . Thus most current GUIs have largely common idioms. GUIs were a hot topic in the early 1980s. The Apple Lisa was released in 1983, and various windowing systems existed for DOS operating systems (including PC GEM and PC/GEOS ). Individual applications for many platforms presented their own GUI variants. Despite

12784-413: The kind of data they hold. The widgets of a well-designed interface are selected to support the actions necessary to achieve the goals of users. A model–view–controller allows flexible structures in which the interface is independent of and indirectly linked to application functions, so the GUI can be customized easily. This allows users to select or design a different skin or theme at will, and eases

12920-408: The lowest version of iOS supported by Xcode 12 built apps is iOS 9. Xcode 12.1 also dropped support for building apps for Mac OS X 10.6 Snow Leopard. The minimum version of macOS supported by Xcode 12.1 built apps is OS X 10.9 Mavericks. Xcode 12 was publicly released on September 16, 2020. On June 7, 2021, at the Apple Worldwide Developers Conference , Xcode version 13 was announced; a beta version

13056-481: The market, the high-right policy was in full force by the mid-1980s, due to Jean-Louis Gassée's slogan of "fifty-five or die", referring to the 55% profit margins of the Macintosh II . This policy began to backfire late in the decade as desktop publishing programs appeared on IBM PC compatibles with some of the same functionality of the Macintosh at far lower price points. The company lost its dominant position in

13192-435: The methods of 3D graphics to project 3D GUI objects onto the screen. The use of 3D graphics has become increasingly common in mainstream operating systems (ex. Windows Aero , and Aqua (MacOS)) to create attractive interfaces, termed eye candy (which includes, for example, the use of drop shadows underneath windows and the cursor ), or for functional purposes only possible using three dimensions. For example, user switching

13328-403: The minimum version of iOS supported by Xcode 14 built apps is iOS 11. Xcode 14 also dropped building apps for macOS 10.12 Sierra. The minimum version of macOS supported by Xcode 14 built apps is macOS 10.13 High Sierra. Xcode 14 was publicly released on September 12, 2022. On June 5, 2023, at the Apple Worldwide Developers Conference , Xcode version 15 was announced; a beta version was released

13464-456: The most part since 2011, Apple has been the world's largest company by market capitalization , and, as of 2023 , is the largest manufacturing company by revenue , the fourth-largest personal computer vendor by unit sales , the largest vendor of tablet computers , and the largest vendor of mobile phones in the world. Apple became the first publicly traded U.S. company to be valued at over $ 1 trillion in 2018, and, as of June 2024 ,

13600-418: The most valuable consumer-facing brand in the world. In June 2011, Jobs surprisingly took the stage and unveiled iCloud , an online storage and syncing service for music, photos, files, and software which replaced MobileMe , Apple's previous attempt at content syncing. This would be the last product launch Jobs would attend before his death. On August 24, 2011, Jobs resigned his position as CEO of Apple. He

13736-409: The new features in Swift 4.2 and Metal 2.1, as well as improvements to the editor and the project build system. Xcode 10 also dropped support for building 32-bit macOS apps and no longer supports Subversion integration. Xcode 10 was publicly released on September 17, 2018. On June 3, 2019, at the Apple Worldwide Developers Conference , Xcode version 11 was announced; a beta version was released

13872-474: The next decade with the introductions of the iMac , iPod , iPhone , and iPad devices to critical acclaim as well as the iTunes Store , launching the " Think different " advertising campaign, and opening the Apple Store retail chain. These moves elevated Apple to consistently be one of the world's most valuable brands since about 2010. Jobs resigned in 2011 for health reasons, and died two months later; he

14008-537: The number 666, and that he came up with the price because he liked "repeating digits". Apple Computer, Inc. was incorporated in Cupertino, California , on January 3, 1977, without Wayne, who had left and sold his share of the company back to Jobs and Wozniak for $ 800 only twelve days after having co-founded it. Multimillionaire Mike Markkula provided essential business expertise and funding of $ 250,000 (equivalent to $ 1,257,000 in 2023) to Jobs and Wozniak during

14144-505: The period between 1989 and 1991 as the "first golden age" of the Macintosh. The success of lower-cost consumer Macs, especially the LC, cannibalized higher-priced machines. To address this, management introduced several new brands, selling largely identical machines at different price points, for different markets: the high-end Quadra series, the mid-range Centris series, and the consumer-marketed Performa series. This led to significant consumer confusion between so many models. In 1993,

14280-403: The pointing device. A window manager facilitates the interactions between windows, applications , and the windowing system . The windowing system handles hardware devices such as pointing devices, graphics hardware, and positioning of the pointer. In personal computers , all these elements are modeled through a desktop metaphor to produce a simulation called a desktop environment in which

14416-448: The present and the future rather than the past. He ended the Mac clone deals and in September 1997, purchased the largest clone maker, Power Computing . On November 10, 1997, the Apple Store website launched, which was tied to a new build-to-order manufacturing model similar to PC manufacturer Dell 's success. The moves paid off for Jobs; at the end of his first year as CEO, the company had

14552-420: The price of Apple's stock increased more than tenfold, from around $ 6 per share ( split-adjusted ) to over $ 80. When Apple surpassed Dell's market cap in January 2006, Jobs sent an email to Apple employees saying Dell's CEO Michael Dell should eat his words. Nine years prior, Dell had said that if he ran Apple he would "shut it down and give the money back to the shareholders". During his keynote speech at

14688-490: The same day. Xcode 11 introduced support for the new features in Swift 5.1, as well as the new SwiftUI framework (although the interactive UI tools are available only when running under macOS 10.15 ). It also supports building iPad applications that run under macOS; includes integrated support for the Swift Package Manager; and contains further improvements to the editor, including a "minimap" that gives an overview of

14824-583: The same day. Xcode 15 dropped support for building apps for iOS 11 and the minimum version of iOS supported by Xcode 15 built apps is iOS 12. Xcode 15 was publicly released on September 18, 2023. On June 10, 2024, at the Apple Worldwide Developers Conference , Xcode version 16 was announced; a beta version was released the same day. Apple Inc. Apple Inc. is an American multinational corporation and technology company headquartered and incorporated in Cupertino, California , in Silicon Valley . It

14960-404: The same time, iOS 8 and Xcode 6 were released. Xcode could be downloaded on the Mac App Store . On June 8, 2015, at the Apple Worldwide Developers Conference , Xcode version 7 was announced. It introduced support for Swift 2, and Metal for OS X , and added support for deploying on iOS devices without an Apple Developer account. Xcode 7 was released on September 16, 2015. On June 13, 2016, at

15096-665: The suite through the Apple Developer website. Xcode includes command-line tools that enable UNIX -style development via the Terminal app in macOS. They can also be downloaded and installed without the GUI . Before Xcode, Apple offered developers Project Builder and Interface Builder to develop Mac OS X applications. Xcode supports source code for the programming languages : Swift , C++ , Objective-C , Objective-C++ , Java , AppleScript , Python , Ruby , ResEdit (Rez), and C , with

15232-509: The system never reached commercial production. The first commercially available computer with a GUI was the 1979 PERQ workstation , manufactured by Three Rivers Computer Corporation. Its design was heavily influenced by the work at Xerox PARC. In 1981, Xerox eventually commercialized the ideas from the Alto in the form of a new and enhanced system – the Xerox 8010 Information System – more commonly known as

15368-492: The term is restricted to the scope of 2D display screens able to describe generic information, in the tradition of the computer science research at the Xerox Palo Alto Research Center . Designing the visual composition and temporal behavior of a GUI is an important part of software application programming in the area of human–computer interaction . Its goal is to enhance the efficiency and ease of use for

15504-456: The underlying logical design of a stored program , a design discipline named usability . Methods of user-centered design are used to ensure that the visual language introduced in the design is well-tailored to the tasks. The visible graphical interface features of an application are sometimes referred to as chrome or GUI . Typically, users interact with information by manipulating visual widgets that allow for interactions appropriate to

15640-466: The user-friendly interface as a personal computer which departed from prior business-oriented systems, and becoming a signature representation of Apple products. In 1985, Commodore released the Amiga 1000 , along with Workbench and Kickstart 1.0 (which contained Intuition ). This interface ran as a separate task, meaning it was very responsive and, unlike other GUIs of the time, it didn't freeze up when

15776-551: Was 2.5. Xcode 3.0 was released with Mac OS X v10.5 "Leopard". Notable changes since 2.1 include the DTrace debugging tool (now named Instruments ), refactoring support, context-sensitive documentation, and Objective-C 2.0 with garbage collection . It also supports Project Snapshots, which provide a basic form of version control; Message Bubbles, which show build errors debug values alongside code; and building four-architecture fat binaries (32 and 64-bit Intel and PowerPC). Xcode 3.1

15912-628: Was an update release of the developer tools for Mac OS X, and was the same version included with the iPhone SDK. It could target non-Mac OS X platforms, including iPhone OS 2.0. It included the GCC 4.2 and LLVM GCC 4.2 compilers. Another new feature since Xcode 3.0 is that Xcode's SCM support now includes Subversion 1.5. Xcode 3.2 was released with Mac OS X v10.6 "Snow Leopard" and installs on no earlier version of OS X. It supports static program analysis , among other features. It also drops official support for targeting versions earlier than iPhone OS 3.0. But it

16048-519: Was delivering a richly engineered but expensive experience. Apple relied on high profit margins and never developed a clear response; it sued Microsoft for making a GUI similar to the Lisa in Apple Computer, Inc. v. Microsoft Corp. The lawsuit dragged on for years and was finally dismissed. The major product flops and the rapid loss of market share to Windows sullied Apple's reputation, and in 1993 Sculley

16184-454: Was finalized on February 9, 1997, and the board brought Jobs back to Apple as an advisor. On July 9, 1997, Jobs staged a boardroom coup that resulted in Amelio's resignation after overseeing a three-year record-low stock price and crippling financial losses. The board named Jobs as interim CEO and he immediately reviewed the product lineup. Jobs canceled 70% of models, ending 3,000 jobs and paring to

16320-475: Was founded on April 1, 1976, by Steve Jobs , Steve Wozniak , and Ronald Wayne as a partnership . The company's first product is the Apple I , a computer designed and hand-built entirely by Wozniak. To finance its creation, Jobs sold his Volkswagen Bus , and Wozniak sold his HP-65 calculator. Neither received the full selling price but in total earned $ 1,300 (equivalent to $ 7,000 in 2023). Wozniak debuted

16456-497: Was founded to produce and market Wozniak's Apple I personal computer. Its second computer, the Apple II , became a best seller as one of the first mass-produced microcomputers . Apple introduced the Lisa in 1983 and the Macintosh in 1984, as some of the first computers to use a graphical user interface and a mouse . By 1985, internal company problems led to Jobs leaving to form NeXT, Inc. , and Wozniak withdrawing to other ventures; John Sculley served as long-time CEO for over

16592-399: Was later introduced by David Canfield Smith , who had written a thesis on the subject under the guidance of Kay. The PARC GUI employs a pointing device along with a keyboard. These aspects can be emphasized by using the alternative term and acronym for windows, icons, menus, pointing device ( WIMP ). This effort culminated in the 1973 Xerox Alto , the first computer with a GUI, though

16728-587: Was launched as Final Cut Pro in April 1999. Key Grip's development also led to Apple's release of the consumer video-editing product iMovie in October 1999. Apple acquired the German company Astarte in April 2000, which had developed the DVD authoring software DVDirector, which Apple repackaged as the professional-oriented DVD Studio Pro , and reused its technology to create iDVD for the consumer market. In 2000, Apple purchased

16864-524: Was more capital than any IPO since Ford Motor Company in 1956. By the end of the day, around 300 millionaires were created, including Jobs and Wozniak, from a stock price of $ 29 per share and a market cap of $ 1.778 billion. In December 1979, Steve Jobs and Apple employees, including Jef Raskin , visited Xerox PARC , where they observed the Xerox Alto , featuring a graphical user interface (GUI). Apple subsequently negotiated access to PARC's technology, leading to Apple's option to buy shares at

17000-574: Was never popular due to its high hardware demands. Nevertheless, it was a crucial influence on the contemporary development of Microsoft Windows . Apple, Digital Research, IBM and Microsoft used many of Xerox's ideas to develop products, and IBM's Common User Access specifications formed the basis of the GUIs used in Microsoft Windows, IBM OS/2 Presentation Manager , and the Unix Motif toolkit and window manager . These ideas evolved to create

17136-493: Was on January 19, 2012, when Apple's Phil Schiller introduced iBooks Textbooks for iOS and iBook Author for Mac OS X in New York City. Jobs stated in the biography Steve Jobs that he wanted to reinvent the textbook industry and education. From 2011 to 2012, Apple released the iPhone 4s and iPhone 5 , which featured improved cameras, an intelligent software assistant named Siri , and cloud-synced data with iCloud;

17272-581: Was only available in beta versions. Xcode 5.0 also added a version of Clang generating 64-bit ARM code for iOS 7. Apple removed support for building garbage collected Cocoa binaries in Xcode 5.1. On June 2, 2014, at the Worldwide Developers Conference, Apple announced version 6 of Xcode. One of the most notable features was support for Swift , an all-new programming language developed by Apple. Xcode 6 also included features like Playgrounds and live debugging tools. On September 17, 2014, at

17408-466: Was publicly released on September 19, 2017. On June 4, 2018, at the Apple Worldwide Developers Conference , Xcode version 10 was announced; a beta version was released the same day. Xcode 10 introduced support for the Dark Mode announced for macOS Mojave , the collaboration platforms Bitbucket and GitLab (in addition to already supported GitHub ), training machine learning models from playgrounds, and

17544-537: Was released in fall 2003. Xcode 1.0 was based on Project Builder , but had an updated user interface (UI), ZeroLink, Fix & Continue, distributed build support, and Code Sense indexing. The next significant release, Xcode 1.5, had better code completion and an improved debugger. Xcode 2.0 was released with Mac OS X v10.4 "Tiger". It included the Quartz Composer visual programming language, better Code Sense indexing for Java, and Ant support. It also included

17680-474: Was released the same day. The new version introduced support for Swift 5.5 and requires macOS 11.3 or later. Xcode 13 contains SDKs for iOS / iPadOS 15 , macOS 12 , watchOS 8 , and tvOS 15 . Xcode 13’s major features include the new concurrency model in Swift projects, improved support for version control providers (such as GitHub ), including the ability to browse, view, and comment on pull requests right in

17816-421: Was released with a few bug fixes. On September 19, 2012, iOS 6 and Xcode 4.5 were released. Xcode added support for iOS 6 and the 4-inch Retina Display on iPhone 5 and iPod Touch 5th generation. It also brought some new Objective-C features to iOS, simplified localization, and added auto-layout support for iOS. On October 3, 2012, Xcode 4.5.1 was released with bug fixes and stability improvements. Less than

17952-577: Was replaced as CEO by Gil Amelio , who was hired for his reputation as a corporate rehabilitator. Amelio made deep changes, including extensive layoffs and cost-cutting. This period was also marked by numerous failed attempts to modernize the Macintosh operating system (MacOS). The original Macintosh operating system ( System 1 ) was not built for multitasking (running several applications at once). The company attempted to correct this by introducing cooperative multitasking in System 5, but still decided it needed

18088-590: Was replaced as CEO by Michael Spindler . Under Spindler, Apple, IBM , and Motorola formed the AIM alliance in 1994 to create a new computing platform (the PowerPC Reference Platform or PReP), with IBM and Motorola hardware coupled with Apple software. The AIM alliance hoped that PReP's performance and Apple's software would leave the PC far behind and thus counter the dominance of Windows. That year, Apple introduced

18224-467: Was replaced by Cook and Jobs became Apple's chairman. Apple did not have a chairman at the time and instead had two co-lead directors— Andrea Jung and Arthur D. Levinson —who continued with those titles until Levinson replaced Jobs as chairman of the board in November after Jobs's death. On October 5, 2011, Steve Jobs died, marking the end of an era for Apple. The next major product announcement by Apple

18360-509: Was succeeded as CEO by Tim Cook . Apple's current product lineup includes portable and home hardware such as the iPhone, iPad, Apple Watch , Mac , and Apple TV ; operating systems such as iOS , iPadOS , and macOS ; and various software and services including Apple Pay , iCloud , and multimedia streaming services like Apple Music and Apple TV+ . Apple is one of the Big Five American information technology companies; for

18496-453: Was the last version to include GNU Compiler Collection (GCC) instead of only LLVM GCC or Clang . On October 12, 2011, Xcode 4.2 was released concurrently with the release of iOS 5.0, and it included many more and improved features, such as storyboarding and automatic reference counting (ARC) . Xcode 4.2 is the last version to support Mac OS X 10.6 "Snow Leopard" , but is available only to registered developers with paid accounts; without
