What is it?
Swift is the newest programming language from Apple; it offers better type safety, security, and performance. Swift is available for developing iOS, OS X, watchOS, and tvOS apps.
Why does it matter?
It’s an easy programming language to learn, which is why many students, entry-level developers, and long-standing Mac and iOS developers are focusing their development skills on Swift. In addition, Apple open sourced Swift, making it available for developing on other platforms, not just those designed by Apple.
Who does this affect?
Apps built with Swift can be run on iOS devices dating back to iOS 7 or later, and OS X devices dating back to OS X 10.9 or later.
When is it available?
Swift is readily available in the most recent version of Xcode.
How can you get it?
Get the latest version of Swift by downloading Xcode from the Mac App Store or the Apple Developer Center. Once Xcode is installed, Swift and the Objective-C compiler (LLVM) will be installed on your Mac.
