"Swift Development Documentation" Swift is an open source programming language that supports multiple programming paradigms and compilation. It was released by Apple at WWDC (Apple Developer Conference) in 2014 and is used to develop iOS, OS X and watchOS applications. Swift combines the best of C and Objective-C without the limitations of C compatibility. Swift can use the same running environment as Objective-C on Mac OS and iOS platforms. Swift is an easy-to-learn and easy-to-use programming language, and it is the first systems programming language to be as expressive and fun as scripting languages. Swift is designed with safety in mind to avoid a variety of common categories of programming errors.
