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.

Networking and Linking to Your Existing App Logic

Whether you're creating a brand new app or building on an existing one, with the best will in the world, at some point, you'll always need to tap into some form of existing framework or legacy code. Regardless of what people may say... that's actually okay.

In this chapter, we'll touch on the basics of networking in SwiftUI and how you might link into an existing networking approach that's commonly used by most iOS apps. Then, we'll deep dive into how we can use and harness existing UIKit Controls and gracefully yet powerfully implement these directly into our SwiftUI app.

The following topics will be covered in this chapter:

  • Basic networking in SwiftUI
  • Integrating UIViews with UIViewRepresentable
  • Integrating ViewControllers with UIViewControllerRepresentable
  • Other representable protocols
