Overview of this book

SwiftUI is the new and powerful interface toolkit that lets you design and build iOS, iPadOS, and macOS apps using declarative syntax. It is a powerful way to develop the UI elements of applications, which would normally be tightly coupled to application logic. Learn SwiftUI will get you up to speed with the framework and cross-device UI development in no time. Complete with detailed explanations and practical examples, this easy-to-follow guide will teach you the fundamentals of the SwiftUI toolkit. You'll learn how to build a powerful iOS and iPadOS application that can be reused for deployment on watchOS. As you progress, you'll delve into UI and unit testing in iOS apps, along with learning how to test your SwiftUI code for multiple devices. The book will also show you how to integrate SwiftUI features such as data binding and network requests into your current application logic. By the end of this book, you will have learned how to build a cross-device application using the SwiftUI framework and Swift programming.

Testing in SwiftUI

In this chapter, we'll explore the fundamentals of testing and debugging and see how we can use the excellent tools already built into Xcode to achieve this.

We'll learn how to incorporate XCTest into our Recipe app for both UI and Unit Test and then go on to write our very own test that we can run against our project.

Finally, we'll cover debugging and how we can stop the process of our app in real-time and use certain tools and commands to inspect elements right within Xcode.

The following topics will be covered in this chapter:

  • Creating our first UI test project and tests
  • Creating our first Unit Test project and tests
  • Debugging in SwiftUI
