and TDD are evergreen programming concepts-yet Swift developers haven't widely adopted them.
What's needed is a clear roadmap to learn and adopt TDD in the Swift world. Apple has invested
heavily in the Swift Testing library and Xcode's testing infrastructure, making testing a first-class
priority in their ecosystem. The tools are there. This book will show you how to wield them.
TDD has much more to offer than catching bugs. With this book, you'll learn a philosophy for building
software. TDD helps you solve problems incrementally, writing only as much code as necessary. By
decomposing big problems into small steps, you can move along at a fast pace, always making visible
progress.
Embark on the Test-Driven Development journey by building a real iOS application and picking up
new techniques in each chapter. The book's concepts will emerge as you figure out ways to use
tests to drive the solutions to the problems of each chapter. You'll be introduced to all the staples
and advanced concepts of the craft, understand the trade-offs each technique offers, and review an
iterative process of software development.
In this fully revised edition, all code is updated to use Apple's new Swift Testing framework, with
networking rewritten using structured concurrency and UI refreshed to match the latest SwiftUI APIs
and iOS 26 design, making it the ideal resource for developers embracing the latest computing and
development tools.
Test-Driven Development in Swift gives you the blueprint for a highly efficient way to make amazing
apps.
What You Will Learn
Write tests that are easy to maintain
Manage and scale an ever-growing test suite
Build a testing vocabulary that transfers beyond Swift
See how Swift's type system enhances the TDD flow of dynamic languages
Discover how compiler errors can provide the same helpful guidance as failing tests
Who This Book Is For
Mid-level developers keen to write higher quality code and improve their workflows. Also, developers that have already been writing tests but feel they are not getting the most out of them.
