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.

Visualizing declarative syntax

As we mentioned in the previous chapter, declarative syntax is used by many languages. A relatively recent framework, Google's Flutter, took on the declarative syntax approach and the wider developer community was immediately hooked. With this, it was only a matter of time before other frameworks started to follow.

At the time of writing this book, Google has just announced Jetpack Compose for Android, which itself adopts the same approach to UI development.

Now, let's take our first steps into programming with SwiftUI. We'll start by getting to grips with Xcode, learn the basics of how to create a new project, and start to write our very first SwiftUI code!
