Chapter 10. Getting Started With Swiftui: User Interfaces…Swiftly
It’s time to use your toolbox full of Swift techniques, features, and components: you’re going to start building user interfaces. A Swift UI, if you will.

We’ll still be using Playgrounds, at least initially, but everything we’re doing here will lay the groundwork for an actual iOS application. Get ready: this chapter is full of code and a lot of new concepts. Take a deep breath, and turn the page to dive into SwiftUI.
