While Apple on Monday seeded the first beta for iOS 8.3, the company also included its first beta for a brand new version of Xcode and a significant upgrade to Swift.On February 9, Apple seeded the first beta for Xcode 6.3, which also includes a brand new version of Apple’s Swift programming language. Swift was first introduced back in June of 2014, when Apple unveiled it at the WWDC event. It’s used for developers to create apps not only for Macs, but also the iPhone, iPad and iPod touch.
“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.“
Apple is self-proclaiming that Swift 1.2 is a “significant update” for the programming language, so it will be interesting to see what developers find in the new release.
