The Swift Programming Language

Swift is a new programming language for creating iOS and OS X apps. Swift builds on the best of C and Objective-C, without the constraints of C compatibility. Swift adopts safe programming patterns and adds modern features to make programming easier, more flexible, and more fun. Swift’s clean slate, backed by the mature and much-loved Cocoa and Cocoa Touch frameworks, is an opportunity to reimagine how software development works. Taking the first steps with Swift -- Learning about variables, constants, strings, and operators -- Optional types -- Using Swift collections -- Control flow -- Functions -- Classes, structures, and protocols -- Using protocols and protocol extensions -- Protocol oriented design -- Generics -- Availability and error handling -- Custom subscripting -- Working with closures -- Concurrency and parallelism in Swift -- Custom types -- Memory management -- Swift formatting and style guider -- Adopting design patterns in Swift.
