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 13: SwiftUI Tips and Tricks

In the previous chapters, we tried to collect different problems, and therefore different recipes, grouping them for a common theme.

In this chapter, instead, the recipes are not connected, apart from the fact that they are solutions for real-world problems.

We'll start viewing two ways of testing SwiftUI's views, and then we'll see how to localize the strings to create an international app.

Sometimes we must show some kind of documentation in the app, so we'll see how to present PDF documents.

One of the coolest features of an iPhone is the possibility of viewing and navigating the real world using its GPS and its map view; you can do this in your app using the MapKit framework, which, though it's not entirely integrated with SwiftUI, we'll see a recipe on how to wrap it and make it work nicely with SwiftUI.

With Swift 1.0, Xcode introduced the possibility of creating coding with Playground, decreasing...
