Swift 3 API Design Guidelines

The design of commonly-used libraries has a large impact on the overall feel of a programming language. Great libraries feel like an extension of the language itself, and consistency across libraries elevates the overall development experience. To aid in the construction of great Swift libraries, one of the major goals for Swift 3 is to define a set of API design guidelines and to apply those design guidelines consistently.The effort to define the Swift API Design Guidelines involves several major pieces that, together, are intended to provide a more cohesive feel to Swift development.Those major pieces are:
