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.

We've covered a lot in this chapter. We've built a brand-new view that makes use of a Form View and sections to allow us to easily create an input form for our recipes. We covered various types of images and how our old friend UIImage comes into play with SwiftUI, allowing us to take a photo from our library and not only insert it into our View but persist and retrieve it when we need to.

We also covered how SwiftUI can integrate into UIKit's existing framework using components that may not necessarily be available yet from SwiftUI, or simply custom components that were created previously and may still add some value.

In the next chapter, we'll be going through this in a little more detail and showing more of the behind the scenes of what we can achieve with SwiftUI in existing applications, including network connectivity.
