Get quick answers for developing anddebugging applications with Swift, Apple’s multi-paradigm programming language.Updated to cover the latest features in Swift 2.0, this pocket reference is theperfect on-the-job tool for learning Swift’s modern language features,including type safety, generics, type inference, closures, tuples, automaticmemory management, and support for Unicode.
Designed to work with Cocoa and Cocoa Touch, Swift can be used in tandem withObjective-C, and either language can call APIs implemented in the other. Swiftis still evolving, but Apple clearly sees it as the future language of choicefor 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
