 Swift 2.2 brings new syntax, new features, and some deprecations too.  It is an interim release before Swift 3 comes later this year [with even bigger changes](/blog/swift-api-transformation/), and the changes in Swift 2.2 align with the broader goals of Swift 3 to focus on gradually stabilizing the core language and Standard Library by adding missing features, refining what is already there, and removing what is no longer needed in the language.  All changes in Swift 2.2 went through the community-driven [Swift evolution process](/contributing/#participating-in-the-swift-evolution-process) &mdash; where over 30 proposals have been submitted, reviewed, and accepted since Swift was open-sourced a few months ago.

 Swift places a lot of emphasis on static typing, but it also supports rich metadata about types, which allows code to inspect and manipulate arbitrary values at runtime. This is exposed to Swift programmers through the `Mirror` API. One might wonder, how does something like `Mirror` work in a language with so much emphasis on static types? Let's take a look!

 It has been a longstanding goal to stabilize Swift’s ABI on macOS, iOS, watchOS, and tvOS.  While a stable ABI is an important milestone for the maturity of any language, the ultimate benefit to the Swift ecosystem was to enable binary compatibility for apps and libraries.  This post describes what binary compatibility means in Swift 5 and how it will evolve in future releases of Swift.
