Following last year’s Swift 3.0 release, Apple has officially released Swift 3.1 today with Xcode 8.3. Now that Swift has hit its first major point release in third iteration, the team will be putting their focus onto Swift 4.

Swift was recently in the spotlight as it’s original creator, Chris Lattner, had left to join become Tesla’s VP of Autopilot Software.

With Swift’s 3.0 release, the teams were looking to “solidify and mature the Swift language and development experience.” From Swift 3.1 and 4+, the language is set to remain source compatible with previous code bases. Swift 4 is expected to hit completion by Fall 2017.

From the official Swift blog, Swift 3.1 came to with fruition thanks to the help of IBM and other contributors.

IBM has released quite a few projects around Apple’s programming language. First off by bringing Swift coding to the web browser with Swift Sandbox, and then by bringing Swift server-side with Bluemix Runtime. With its Kitura project, IBM made it possible for developers to build front-end and back-end code all in Swift.

More information on the official release of Swift 3.1 can be found over at the official Swift blog. The latest build of Xcode can be found in the Mac App Store.
