The iOS SDK (iOS Software Development Kit), formerly the iPhone SDK, is a software development kit (SDK) developed by Apple Inc. The kit allows for the development of mobile apps on Apple's iOS and iPadOS operating systems.

The iOS SDK is a free download for users of

App Store, developers are required to subscribe to the Apple Developer Program
.

Combined with Xcode, the iOS SDK helps developers write iOS apps using officially supported programming languages, including Swift and Objective-C. Other companies have also created tools that allow for the development of native iOS apps using their respective programming languages.

History

While originally developing

CEO Steve Jobs did not intend to let third-party developers build native apps for the iOS operating system, instead directing them to make web applications for the Safari web browser.[1] However, backlash from developers prompted the company to reconsider,[1] with Jobs announcing on October 17, 2007, that Apple would have a software development kit (SDK) available for developers by February 2008.[2][3] The SDK was released on March 6, 2008.[4][5]

Features

The iOS SDK is a free download for

App Store, developers are required to subscribe to the Apple Developer Program.[6]

The SDK contents are separated into the following sets:[7]

The SDK also contains an iPhone simulator, a program used to simulate the look and feel of iPhone on the developer's computer.[7]

New SDK versions accompany new iOS versions.[8][9]

Programming languages

The iOS SDK, combined with Xcode, helps developers write iOS applications using officially supported programming languages, including Swift and Objective-C.[10]

An .ipa (iOS App Store Package) file is an iOS application archive file which stores an iOS app.

Java

In 2008,

ARM chip with a processor with Jazelle support for embedded Java execution.[15]

.NET

Novell announced in September 2009 that they had successfully developed MonoTouch, a software framework that let developers write native iPhone applications in the C# and .NET programming languages, while still maintaining compatibility with Apple's requirements.[16]

Flash

iOS does not support

Adobe has two versions of its software: Flash and Flash Lite, Apple views neither as suitable for the iPhone, claiming that full Flash is "too slow to be useful", and Flash Lite to be "not capable of being used with the Web".[18][19]

In October 2009, Adobe announced that an upcoming update to its

Creative Suite 5 collection of professional applications.[21]

2010 policy on development tools

In April 2010,

App Store, and banning applications that used third-party development tools; the ban affected Adobe's Packager tool, which converted Flash apps into iOS apps.[22][23] After developer backlash[24] and news of a potential anti-trust investigation,[25] Apple again revised its agreement in September, allowing the use of third-party development tools.[24][26]

Mac Catalyst

Originally called "Project Marzipan",[27] Mac Catalyst helps developers bring iPadOS app experiences to macOS, and make it easier to take apps developed for iPadOS devices to Macs by avoiding the need to write the underlying software code twice.
