Alongside iOS 8.3 beta 1, Apple released Xcode 6.3 beta with a new version of Swift, its programming language for Cocoa and Cocoa Touch used by developers to write apps for the iPhone, iPad, iPod touch, and Mac. The new release brings Swift, which was first announced last June at WWDC 2014, up to version 1.2.

Xcode 6.3 includes a new version of the Swift language. It includes a number of noteworthy changes to the language, detailed in the New in Xcode 6.3 beta section. Xcode 6.3 provides a migrator for moving your code to Swift 1.2.

Swift 1.2 is described as a “significant update” to the programming language while changes are highlighted on Apple’s Swift blog. Last month Stanford University published its own course to iTunes U on developing applications using Apple’s Swift programming language.
