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.

Creating Your First Application

In this chapter, we'll begin to code our very first app in SwiftUI exciting, I know, but before we learn to run, we need to walk a little further first. The Xcode IDE will play a fundamental role in our journey, so we'll cover the basics and core components in a little more detail. We'll look at how Xcode allows us to write our SwiftUI code and give us almost immediate feedback. We'll also touch on how and, more importantly, why we may need to use the iOS simulator to run our app in certain scenarios.

The following topics will be covered in this chapter:

  • Xcode, as an IDE
  • Core components of Xcode
  • Mock data in Automatic Preview
