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.

Chapter 1: Using the Basic SwiftUI Views and Controls

In this chapter, we'll learn about SwiftUI's innovative way of building user interfaces across all platforms. SwiftUI does not use UIKit concepts such as Auto Layout. It has a completely new layout system designed to make it easy to write applications that work across Apple platforms.

We'll also learn about views and controls, SwiftUI's visual building blocks for app interfaces. We will look at how to use text, images, buttons, navigation, and much more.

By the end of the chapter, you'll be able to combine various views and components to create crisp and beautiful user interfaces.

In this chapter, we will cover the following recipes:

  • How to lay out components
  • Dealing with text
  • Using images
  • Adding buttons and navigating with them
  • Beyond buttons – how to use advanced pickers
  • How to apply groups of styles using ViewModifiers
  • Separating presentation from content...
