Learning Swift Programming

Get started fast with Swift programming for iOS and OS X   Learning Swift Programming is a fast-paced, hands-on introduction to writing production-quality iOS and OS X apps with Apple’s new programming language. Written for developers with previous experience in any other modern language, this book explains Swift simply and clearly, using relevant examples that solve realistic problems.   Author Jacob Schatz’s popular Skip Wilson video tutorials on YouTube have already helped thousands of Apple developers get started with Swift. Now, he helps you take full advantage of Swift’s advanced design, remarkable performance, and streamlined development techniques.   Step-by-step, you’ll move from basic syntax through advanced features such as closures and generics–discovering helpful tips and tricks along the way. After you’ve mastered Swift’s building blocks and learned about its key innovations, a full section of case studies walks you through building complete apps from scratch. Compare Swift with Objective-C, JavaScript, Python, Ruby, and C Collect data with arrays and dictionaries, and store it with variables and constants Group commonly-used code into functions for easy reuse Structure your code with enums, structs, and classes Use generics to get more done with less code Write closures to share small blocks of functionality Use optionals to write more robust, crash-resistant, and cleaner code Integrate existing Objective-C code into new Swift apps Program on the bit and byte level with advanced operators Implement efficient design patterns with protocols and delegates Create animated 2D games with SpriteKit, and 3D games with SceneKit Contents at a Glance 1 Getting Your Feet Wet     Building Blocks of Swift     Optionals: A Gift to Unwrap     Tuples     Number Types and Converting Between Them     Coming to Swift from Objective-C and C 2 Collecting Data     Using Arrays     Modifying Arrays     Using Dictionaries 3 Making Things Happen: Functions     Defining Functions     More on Parameters 4 Structuring Code: Enums, Structs, and Classes     Enums     Structs 5 Making a Game     Building a User Interface (UI)     The Action-Packed View Controller 6 Reusable Code: Closures     What Are Closures?     Closures in Other Languages     How Closures Work and Why They’re Awesome 7 Subscripts and Advanced Operators     Writing Your First Subscript     Bits and Bytes with Advanced Operators     Customizing Operators     Making Your Own Operators     Bits and Bytes in Real Life 8 Protocols     Writing Your First Protocol     Animizable and Humanizable     Delegation     Protocols as Types     Protocols in Collections     Optional Chaining 9 Becoming Flexible with Generics     The Problem That Generics Solve 10 Games with SpriteKit      Setting Up the Project      The Start Screen      Dangerous Ground      A Hero to the Rescue      Enemies in Motion      Spawned Obstacles      Smashing Physics 11 Games with SceneKit      Creating DAE Files      Creating a New SceneKit Project      Your SceneKit Files      Making the Game      Bridging the Gap to Objective-C 12 Apps with UIKit      Application Types      Loading a Table View      Loading Data from a URL
