Move into iOS development by getting a firm grasp of its fundamentals, including the Xcode IDE, the Cocoa Touch framework, and Swift 3-the latest version of Apple's acclaimed programming language. With this thoroughly updated guide, you'll learn Swift's object-oriented concepts, understand how to use Apple's development tools, and discover how Cocoa provides the underlying functionality iOS apps need to have.

Explore Swift's object-oriented concepts: variables and functions, scopes and namespaces, object types and instances
Become familiar with built-in Swift types such as numbers, strings, ranges, tuples, Optionals, arrays, dictionaries, and sets
Learn how to declare, instantiate, and customize Swift object types: enums, structs, and classes
Discover powerful Swift features such as protocols and generics
Catch up on Swift 3 innovations: revised APIs, new Foundation bridged types, and more
Tour the lifecycle of an Xcode project from inception to App Store-including Xcode's new automatic code signing and debugging features
Construct app interfaces with the nib editor, Interface Builder
Understand Cocoa's event-driven model and its major design patterns and features
Find out how Swift communicates with Cocoa's C and Objective-C APIs
Once you master the fundamentals, you'll be ready to tackle the details of iOS app development with author Matt Neuburg's companion guide, Programming iOS 10.
