This document discusses the evolution of Swift and its goals for versions 2.2 and 3.0. It notes that Swift spans from low-level firmware to high-level applications. Timelines show implemented and accepted proposals for Swift 2.2, including allowing keywords as argument labels and tuple comparison operators. Goals for 3.0 focus on stability, portability, and refinements to the type system and generics. The document encourages using and contributing to Swift's development through research, discussion, and patience.
