I know the feeling of being on the verge of learning something new. If you’re anything like me, you’re eager to try things out and see how it feels. And that’s exactly what you do in this chapter!

In this chapter, I explain what SwiftUI is, show you how SwiftUI has changed the user interface (UI) development paradigm, and explain how SwiftUI makes the process easier going forward. Then I tell you how you can get started with the necessary tools. Finally, with the tools that you’ve installed, you create your first iOS application using SwiftUI, and learn how the various components in your project work together as a whole.
