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.

SwiftUI versus UIKit

So far, we've covered many of the benefits of using SwiftUI and also seen how we can utilize UIKit within our SwiftUI projects, but what impact does SwiftUI really have when it comes to developing our apps?

This chapter is intended as a reference and is aimed at those who are new to SwiftUI but have an understanding of UIKit and are looking to make comparisons. It is also intended for those who are brand new to development with SwiftUI and want to learn a little more about the benefits compared to UIKit.

The following topics will be covered in this chapter:

  • List view versus UITableView
  • Data Binding versus Data Source
  • Comparing decoration techniques
  • Migrating UIKit so that it's ready for SwiftUI
