Author Jacob Schatz's popular YouTube video tutorials 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.

Learn how to:

• 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 levels with advanced operators
• Implement efficient design patterns with protocols and delegates
• Create animated 2D games with SpriteKit, and apps with UIKit
