SwiftUI Projects

Overview of this book

Released by Apple during WWDC 2019, SwiftUI provides an innovative and exceptionally simple way to build user interfaces for all Apple platforms with the power of Swift. This practical guide involves six real-world projects built from scratch, with two projects each for iPhone, iPad, and watchOS, built using Swift programming and Xcode. Starting with the basics of SwiftUI, you’ll gradually delve into building these projects. You’ll learn the fundamental concepts of SwiftUI by working with views, layouts, and dynamic types. This SwiftUI book will also help you get hands-on with declarative programming for building apps that can run on multiple platforms. Throughout the book, you’ll work on a chart app (watchOS), NBA draft app (watchOS), financial app (iPhone), Tesla form app (iPhone), sports news app (iPad), and shoe point-of-sale system (iPad), which will enable you to understand the core elements of a SwiftUI project. By the end of the book, you’ll have built fully functional projects for multiple platforms and gained the knowledge required to become a professional SwiftUI developer.

Building out our navigation

SwiftUI is now fully supported in watchOS 7, which means we do not have to work with some of the older controllers pre watchOS 6. We will first create our entire navigation, and then we will go back and build out each view. Let's get started by opening ContentView first.

Creating a static list

Our List, in this view, is going to be a static list with just two links. One will present a modal, and the other will do the standard push to detail view. Add the following after the struct declaration:

@State private var isPresented = false

In the last chapter, we skipped @State because it was not in scope, and I will do it again as I cover this in greater detail in Сhapter 5, Car Order Form – Data. But I will, for now, just say we are creating a Boolean that keeps track of the modal presentation. Next, inside the body variable, replace Text ('Content View') with the following:

List {
