Get quick answers for developing and debugging applications with Swift, Apple’s multi-paradigm programming language. Updated to cover the latest features in Swift 2.0, this pocket reference is the perfect on-the-job tool for learning Swift’s modern language features, including type safety, generics, type inference, closures, tuples, automatic memory management, and support for Unicode.Designed to work with Cocoa and Cocoa Touch, Swift can be used in tandem with Objective-C, and either language can call APIs implemented in the other.
Swift is still evolving, but Apple clearly sees it as the future language of choice for iOS and OS X software development.Topics include:Supported data types, such as strings, arrays, array slices, sets, and dictionariesProgram flow: loops, conditional execution, and error handlingClasses, structures, enumerations, and functionsProtocols, extensions, and genericsMemory managementClosures: similar to blocks in Objective-C and lambdas in C#Optionals: values that can explicitly have no valueOperators, operator overloading, and custom operatorsAccess control: restricting access to types, methods, and propertiesRanges, intervals, and stridesA full list of built-in global functions and their parameter requirements
