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.

Adding a Map with MapKit control

As we learned in the previous chapter, Chapter 8, Networking and Linking to Your Existing App Logic, working with existing app logic will require you from time to time to make use of 0f UIViewRepresentable and/or UIViewControllerRepresentable when implementing existing UIKit features. MapKit is currently no exception to this, and in this section, we'll start to build our MapView using this methodology. We'll create a UIViewRepresentable struct around the current MapKit control and add this directly into our SwiftUI recipe app.

Implementing MapKit

We'll start by creating a new SwiftUI View; we'll create a new file in our Xcode project called RecipeMapView by highlighting...
