About this book

Get quick answers for developing and debugging applications with Swift Apples 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 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 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 dictionaries Program flow: loops conditional execution and error handling Classes structures enumerations and functions Protocols extensions and generics Memory management Closures: similar to blocks in Objective-C and lambdas in C# Optionals: values that can explicitly have no value Operators operator overloading and custom operators Access control: restricting access to types methods and properties Ranges intervals and strides A full list of built-in global functions and their parameter requirements
