Beschreibung
Get quick answers for developing and debugging applications with Swift, Apples multi-paradigm programming language. This pocket reference is the perfect on-the-job tool for learning Swifts 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 of these languages can call APIs implemented in the other. Swift is still evolving, but its clear that Apple sees it as the future language of choice for iOS and OS X software development.Topics include:Swifts Run-Eval-Print-Loop (REPL) and interactive playgroundsSupported data types, such as strings, arrays, and dictionariesVariables and constantsProgram flow: loops and conditional executionClasses, structures, enumerations, functions, and protocolsClosures: 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 propertiesBuilt-in global functions and their parameter requirements
