Swift is Apple’s programming language for developers to use with iOS and OS X devices. Swift has been designed both to work alongside its predecessor, Objective-C, and to one day be Objective-C’s replacement. When you develop apps for iOS or OS X, you use the Xcode development tool (technically an Integrated Development Environment, or IDE), the Cocoa or Cocoa Touch frameworks, and a programming language —either Objective-C or Swift. Swift inherits much of Objective-C’s functionality — anyone comfortable with Objective-C’s types, collections, functions, classes, and flow control will be familiar with those structures in Swift, as well.
