SwiftUI Cookbook

Overview of this book

SwiftUI is an innovative and simple way to build beautiful user interfaces (UIs) for all Apple platforms, right from iOS and macOS through to watchOS and tvOS, using the Swift programming language. In this recipe-based book, you’ll work with SwiftUI and explore a range of essential techniques and concepts that will help you through the development process. The recipes cover the foundations of SwiftUI as well as the new SwiftUI 2.0 features introduced in iOS 14. Other recipes will help you to make some of the new SwiftUI 2.0 components backward-compatible with iOS 13, such as the Map View or the Sign in with Apple View. The cookbook begins by explaining how to use basic SwiftUI components. Then, you’ll learn the core concepts of UI development such as Views, Controls, Lists, and ScrollViews using practical implementation in Swift. By learning drawings, built-in shapes, and adding animations and transitions, you’ll discover how to add useful features to the SwiftUI. When you’re ready, you’ll understand how to integrate SwiftUI with exciting new components in the Apple development ecosystem, such as Combine for managing events and Core Data for managing app data. Finally, you’ll write iOS, macOS, and watchOS apps while sharing the same SwiftUI codebase. By the end of this SwiftUI book, you'll have discovered a range of simple, direct solutions to common problems found in building SwiftUI apps.

Simple graphics using SF Symbols

The San Francisco Symbols (also known as SF Symbols) provide a set of over 1,500 consistent and highly configurable symbols.

To browse through the list or look at symbol names, you can download the SF Symbols app from

In this recipe, we will create a project that uses various SF Symbols and applies different styles to them.

Getting ready

Create a new SwiftUI project named SFSybmolsApp.

How to do it…

Using SF Symbols is very similar to using images.

  1. Open the ContentView.swift file and delete the default Text view.
  2. Add a VStack and an HStack to the ContentView body and implement various SF symbols:
    VStack {
                    Image(systemName: "")
