Swift 2.2 Released! March 21, 2016 Ted Kremenek is a member of the Swift Core Team and manages the Languages and Runtimes group at Apple.

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.

Swift 2.2 is a minor language release that is mostly source-compatible with Swift 2.1. It contains the following language changes that went through the Swift’s evolution process:

Beyond these language changes Swift 2.2 also contains numerous bug fixes, enhancements to diagnostics, and produces even faster-running code.

The Swift Package Manager is still early in development and is not included in this release.
