iOS SDK

The iOS SDK (iOS Software Development Kit), formerly the iPhone SDK, is a <a href="/facts/Software_development_kit/2Hkk6Hbs">software development kit</a> (SDK) developed by <a href="/facts/Apple_Inc./oTJYta3k">Apple Inc.</a> The kit allows for the development of <a href="/facts/Mobile_app/r7vp6meo">mobile apps</a> on Apple's <a href="/facts/IOS/mK5cggH5">iOS</a> and <a href="/facts/IPadOS/fClrmH7D">iPadOS</a> operating systems.
The iOS SDK is a free download for users of <a href="/facts/Macintosh/8GhnXTK0">Macintosh</a> (or Mac) personal computers. It is not available for <a href="/facts/Microsoft_Windows/bwhAhuSL">Microsoft Windows</a> PCs. The SDK contains sets giving developers access to various functions and services of iOS devices, such as <a href="/facts/Computer_hardware/8jSjsCNv">hardware</a> and <a href="/facts/Software/RP79lVSW">software</a> attributes. It also contains an iPhone <a href="/facts/Simulator/Q4QJV1oI">simulator</a> to mimic the look and feel of the device on the computer while developing. New versions of the SDK accompany new versions of iOS. In order to test applications, get technical support, and distribute apps through <a href="/facts/App_Store_(iOS%2fiPadOS)/0yqcGqey">App Store</a>, developers are required to subscribe to the <a href="/facts/Apple_Developer/mHaKzeRs">Apple Developer Program</a>.
Combined with <a href="/facts/Xcode/glURdIVT">Xcode</a>, the iOS SDK helps developers write iOS apps using officially supported <a href="/facts/Programming_language/cWTYbgWa">programming languages</a>, including <a href="/facts/Swift_(programming_language)/A7qHQC32">Swift</a> and <a href="/facts/Objective-C/5mM557BW">Objective-C</a>. Other companies have also created tools that allow for the development of native iOS apps using their respective programming languages.
