Heads up... You're reading this book for free, with parts of this chapter shown beyond this point as scrambled text.

We hope you’re as excited about SwiftUI as we are! This new approach to building user interfaces might seem a bit strange at the start. But we’re sure that if you’ve worked through the chapters in this book, you now have a much better understanding of declarative programming and the infinite possibilities of SwiftUI. Remember, SwiftUI is a new, modern approach, so it keeps improving; it still has a lot to learn and a lot of growing ahead. And you’ve also just made your own first steps in working with this wonderful new framework.

The possibility of using SwiftUI for all Apple devices opens up the playing field for a greater number of developers on all Apple platforms, which will hopefully turn into many more amazing apps adapted for the iPhone, Mac, iPad, Apple Watch, Apple TV… and even new devices to come!

We encourage you to try to put the book concepts in practice. Combine SwiftUI with UIKit & AppKit and see how well they get along together. Try Stacks, navigation, testing, and all the cool concepts explained throughout the book. Keep learning, and share your projects with us!
