This is a book for complete beginners to Apple’s modern programming language — Swift. All the code in the book works inside of Xcode’s easy-to-use playgrounds. That means you can focus on core Swift language concepts, such as classes, protocols, and generics, instead of getting bogged down in the details of building apps. This is a companion book to the SwiftUI Apprentice; the SwiftUI Apprentice focuses on building apps, while Swift Apprentice focuses on the Swift language itself.

Welcome to the Swift Apprentice, fully updated for Xcode 13 and Swift 5.5! In the last seven years, Swift has gone from a secret project at Apple, Inc. to a full-blown, open-source, community-driven language. It continues to refine its core goal of being a general-purpose language that supports safety, speed and expressiveness. Despite its progressive, industrial-strength nature, Swift is an excellent choice for the beginning programmer since Xcode offers a sandbox-type environment where you can directly execute Swift statements to try out various language features without creating a whole app first.

Developers worldwide use Swift to build thousands of amazing apps for iOS, iPadOS, macOS, tvOS and watchOS. Swift is also in server-side technology on non-Apple platforms. That means what you learn in this book will be extremely useful as you expand your development skills and possibly work as a developer someday.

You’ll learn about basic things like constants, values, operations and types, and move up to more intermediate concepts like data structures, classes and enumerations. Finally, you’ll finish off by getting in-depth knowledge about protocol extensions, custom operators, protocol-oriented programming and generics. Swift lets you create beautiful abstractions to solve real-world problems that you will learn about in this book. Swift is also a lot of fun! It’s easy to try out small snippets of code as you test new ideas. Programming is a hands-on experience, and Swift makes it fast and easy to follow along with this book and explore on your own.

Who this book is for:
If you’re a complete beginner at programming, this is the book for you! There are short exercises and challenges throughout the book to give you some programming practice and test your knowledge along the way. If you want to get right into iOS app development while learning bits of the Swift language as you go, we recommend SwiftUI by Tutorials by the raywenderlich.com team. SwiftUI is so approachable that you may have even built a simple app or two with some sample code. As you go through this book, you may be wondering why you don’t see some of the syntaxes that appear in an elementary SwiftUI app. These include @State and @ObservedObject property wrappers, opaque return types and result builders. While property wrappers and opaque return types are eventually covered, they are advanced language features and require quite a bit of background to understand their inner workings. Using them, fortunately, is easy, and SwiftUI by Tutorials will show you how to do that.
