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.

Creating a chart Page-View navigation

Next, we are going to create a Page View navigation controller. Just as you would expect on a phone, you will be able to swipe from the right to left and see different content on each page. You will also see some dots at the bottom of the page, which shows which page is being displayed currently.

Open ChartsView and let's get started. Inside the body variable, replace Text('Charts View') with the following:

TabView { // Step 1
    BarChartView() // Step 2
    WedgeChartView() 
    RingView() 
}.tabViewStyle(PageTabViewStyle(indexDisplayMode: .automatic))     // Step 3

We just added all of the code for ChartsView, so let's look at what we did:

  1. We wrap all of our views inside a TabView.
  2. Next, we set up each page by just listing them inside the TabView.
  3. We set the .tabViewStyle() modifier to PageTabViewStyle(indexDisplayMode...
