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.

Implementing a multilanguage app with localized strings in SwiftUI

One of the beauties of iOS and the Apple App Store is that you can sell your app to the whole world, just by configuring the markets in App Store Connect.

Given that, you must consider that only one language is not enough, and you should customize the app to be presented in the language of your customers. The localization mechanism in iOS is sophisticated, and luckily it works very well in SwiftUI too.

In this recipe, we'll create a sample app that presents a cooking recipe detail page, and we are going to localize it in English, French, and Italian.

Getting ready

Let's start by creating a SwiftUI app called RecipeApp in Xcode.

We are going to use an image for the recipe, and you can find it in the GitHub repo here: https://github.com/PacktPublishing/SwiftUI-Cookbook/blob/master/Resources/Chapter13/recipe3/recipe.jpg.
