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.

Integrating Firebase into a SwiftUI project

Firebase is a mobile development platform that has several products that simplify the implementation of mobile apps. These apps need a backend for persistence, authentication, notifications, and more. A mobile developer can concentrate on implementing only the mobile app without worrying about implementing the services on the cloud that they need to power their app.

Firebase provides a framework so that their services can be used in Swift. Unfortunately, not all of them work smoothly in SwiftUI, so you need to apply some workarounds. Hopefully, Firebase will release a version for SwiftUI soon. We'll start our exploration of Firebase in SwiftUI by integrating their RemoteConfig product.

RemoteConfig is a service that lets the developer change the behavior or appearance of the app without requiring the users to download an update of the app. In this recipe, we are going to implement two sample main screens so that the developer...
