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.

Chapter 12: Cross-Platform SwiftUI

SwiftUI makes it easy to take some or all of the code written for one Apple platform, and use it to create an app for another platform in the Apple ecosystem. For example, in this chapter, we start by creating an iOS app and then reusing some of the components to create a macOS and a watchOS app.

When using Cross-Platform development in SwiftUI, we share common resources between each platform, while creating other resources that are platform-specific. For example, models may be shared across platforms, but certain images and SwiftUI views would be made platform-specific. Creating platform-specific views allows us to follow platform-specific best-practice design guidelines and improve the user experience provided by our apps.

This chapter covers some of the Cross-Platform functionalities of SwiftUI with the following recipes:

  • Creating an iOS app in SwiftUI
  • Creating the macOS version of the iOS app
  • Creating the watchOS version...
