Test-Driven Development in Swift

Leverage Swift to practice effective and efficient Test-Driven Development (TDD). Software testingand 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 investedheavily in the Swift Testing library and Xcode’s testing infrastructure, making testing a first-classpriority 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 buildingsoftware. TDD helps you solve problems incrementally, writing only as much code as necessary. Bydecomposing big problems into small steps, you can move along at a fast pace, always making visibleprogress. Embark on the Test-Driven Development journey by building a real iOS application and picking upnew techniques in each chapter. The book’s concepts will emerge as you figure out ways to usetests to drive the solutions to the problems of each chapter. You’ll be introduced to all the staplesand advanced concepts of the craft, understand the trade-offs each technique offers, and review aniterative process of software development. In this fully revised edition, all code is updated to use Apple’s new Swift Testing framework, withnetworking rewritten using structured concurrency and UI refreshed to match the latest SwiftUI APIsand iOS 26 design, making it the ideal resource for developers embracing the latest computing anddevelopment tools. Test-Driven Development in Swift gives you the blueprint for a highly efficient way to make amazingapps.    What You Will Learn:Write tests that are easy to maintainManage and scale an ever-growing test suiteBuild a testing vocabulary that transfers beyond SwiftSee how Swift’s type system enhances the TDD flow of dynamic languagesDiscover how compiler errors can provide the same helpful guidance as failing testsWho This Book Is ForMid-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.
