Mastering Swift 5: Deep dive into the latest edition of the Swift programming language, 5th Edition

Book Description

Over the years, Mastering Swift has established itself among developers as a popular choice as an in-depth and practical guide to the Swift programming language. This latest edition is fully updated and revised to cover the new version – Swift 5. With this book, you’ll explore the key features of Swift 5, easily explained with complete sets of examples. From the basics of the language to popular features such as concurrency, generics, and memory management, this in-depth guide will help you develop your expertise and mastery in the language.

As you progress, you’ll gain practical insights into some of the most sophisticated elements in Swift development, including protocol extensions, error handling, and closures. The book will also show you how to use and apply them in your own projects. In later chapters, you’ll understand how to leverage the power of protocol-oriented programming to write flexible and easier-to-manage code. Finally, you’ll learn how to add the copy-on-write feature to your custom value types, along with understanding how to avoid memory management issues caused by strong reference cycles.

By the end of this book, you will have mastered the Swift 5 language and developed the skills you need to effectively use its features to build robust applications.

What you will learn

• Understand core Swift components, such as operators, collections, control flows, and functions
• Learn how and when to use classes, structures, and enumerations
• Understand how to use protocol-oriented design with extensions to write easier-to-manage code
• Use design patterns with Swift to solve commonly occurring design problems
• Apply copy-on-write for your custom value types to improve performance
• Add concurrency to your applications using Grand Central Dispatch and Operation Queues
• Implement generics to write flexible and reusable code

Who this book is for
