Learning Swift™ Programming

How This Book Is Organized

This book is divided into 12 chapters, which cover the language itself and walk you through creating a few apps:

■ Chapters 1–4 cover basic language syntax, including variables, constants, arrays, dictionaries, functions, classes, enums, and structs. These are the basic building blocks of the Swift language.

■ Chapter 5 takes a break from the language syntax and helps you create a basic game of tic-tac-toe.

■ Chapters 6–9 cover more advanced language features, including closures, subscripts, advanced operators, protocols and extensions, generics, and programming on the bit and byte levels.

■ Chapters 10–12 show you how to create real-world apps using the knowledge you’ve gained from previous chapters.
