Overview of this book

SwiftUI is the new and powerful interface toolkit that lets you design and build iOS, iPadOS, and macOS apps using declarative syntax. It is a powerful way to develop the UI elements of applications, which would normally be tightly coupled to application logic. Learn SwiftUI will get you up to speed with the framework and cross-device UI development in no time. Complete with detailed explanations and practical examples, this easy-to-follow guide will teach you the fundamentals of the SwiftUI toolkit. You'll learn how to build a powerful iOS and iPadOS application that can be reused for deployment on watchOS. As you progress, you'll delve into UI and unit testing in iOS apps, along with learning how to test your SwiftUI code for multiple devices. The book will also show you how to integrate SwiftUI features such as data binding and network requests into your current application logic. By the end of this book, you will have learned how to build a cross-device application using the SwiftUI framework and Swift programming.

Using our fonts in this way allows us to easily keep a consistent look throughout the app, with very little effort. Next, we looked at how to add color and how to amend the weight of our Text with the use of modifiers. From this, we added another Text View and saw that by using a VStack, we could obtain our desired look.

In order to preview our data without the need to launch the app in the simulator, we updated PreviewProvider with mock data, thus allowing us to easily identify how our View would look and feel.

After we added text to each row in our List View, we extracted this in order to make it reusable throughout the app. This is an important subject in app development, as some Views can easily become either very complex or...
