Swift 2.2 Released!

We are very pleased to announce the release of Swift 2.2! This is the first official release of Swift since it was open-sourced on December 3, 2015. Notably, the release includes contributions from 212 non-Apple contributors — changes that span from simple bug fixes to enhancements and alterations to the core language and Swift Standard Library.

Apple launched Swift as an open source project with the Swift.org site, which includes key parts like the compiler, standard library, LLDB debugger, core libraries, and package manager. They also released a Linux port for testing, without Objective-C runtime, but with support for core features and plans to fix missing parts like some APIs and libdispatch.

For Swift 3, they set API design guidelines to make code feel more consistent across the standard library and imported Objective-C APIs. They added continuous integration via Jenkins for builds and tests on macOS, iOS, and Linux, plus an open source benchmark suite to track performance.

Swift 2.2 came out as the first release after open source, with minor language changes, bug fixes, Linux support, and input from over 200 outside contributors.
