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.

List view versus UITableView

Now that we've got a comprehensive understanding of SwiftUI, let's take some time to compare the benefits of SwiftUI against Apple's original UI Framework UIKit. In this section, we'll take a look at the simplicity of a List() View in SwiftUI and compare this to how we'd construct a UITableView() in UIKit.

Basic UITableView implementation

Let's start by checking out exactly how we'd create a list, similar to the one found in our ListView.swift file.

Although we can make use of Storyboards to create TableViews, for this comparison, we'll give all our examples programmatically so that we can provide a more direct comparison with the declarative syntax we&apos...
