SwiftUI Cookbook - Second Edition

By: Giordano Scalzo, Edgar Nzokwe

Overview of this book

SwiftUI provides an innovative and simple way to build beautiful user interfaces (UIs) for all Apple platforms, from iOS and macOS through to watchOS and tvOS, using the Swift programming language. In this recipe-based cookbook, you’ll cover the foundations of SwiftUI as well as the new SwiftUI 3 features introduced in iOS 15 and explore a range of essential techniques and concepts that will help you through the development process. The cookbook begins by explaining how to use basic SwiftUI components. Once you’ve learned the core concepts of UI development, such as Views, Controls, Lists, and ScrollViews, using practical implementations in Swift, you'll advance to adding useful features to SwiftUI using drawings, built-in shapes, animations, and transitions. 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 by 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 encountered when building SwiftUI apps.

Dealing with text

The most basic building block of any application is text, which we use to provide or request information from a user. Some text requires special treatment, such as password fields, which must be hidden.

In this recipe, we will implement different types of SwiftUI Text views. A Text view is used to display one or more lines of read-only text on the screen. A TextField view is used to display multiline editable text, and a SecureField view is used to request private information that should be hidden, such as passwords.

Getting ready

Create a new SwiftUI project named FormattedText.

How to do it…

We'll implement multiple types of text-related views and modifiers. Each step in this section applies minor changes to the view, so note the UI changes that occur after each step. Let's get started:

  1. Enclose the initial ContentView text in a VStack:
    struct ContentView: View {
    var body: some View {
          &...
