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.

Charts

Building charts is pretty fun in SwiftUI because it requires very little code. Here is an example of the three screens that we are looking to create in this section:

We will start on the Bar Chart first using the Capsule shape.

Bar charts

Bar charts are a great way to display information to users. In this example, we will create a static Bar Chart that you can use to display data on the watch. We can also take all of these examples and show them on the larger screens of other devices. Whenever we work in SwiftUI, we will use Swift Previews to review our work, making our workflow go much faster than having to wait for the simulator to launch and display. Please note that to use Swift Previews, you must be on macOS Catalina. If you are not, then just run the simulator.

Creating a header

First, we will start by creating our header for our view. This view is just two text views stacked horizontally next to each other. Open BarChartView...
