SwiftUI Cookbook

By: Giordano Scalzo, Edgar Nzokwe

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.

Dealing with text

The SwiftUI text struct is a view that displays one or more lines of read-only text. Text structs come with a number of standard modifiers to format text. In this section, we will create a project that applies modifiers to 10 different texts.

We will also implement TextField, which is used to display an editable text interface. We will also look at SecureField. SecureField is almost identical to TextField, but masks its content for privacy.

Getting ready

Create a new SwiftUI project named FormattedText.

How to do it…

  1. Enclose the text in the body view with a VStack:
    struct ContentView: View {
        var body: some View {
                Text("Hello World")
  2. Add the .fontWeight(.medium) modifier to the text and observe...
