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.

Basic networking in SwiftUI

In this section, we'll start by covering networking with SwiftUI. We touched on the basics of how we could implement this using the MVVN pattern back in Chapter 3, Building Layout and Structure, but now that we're building our app, let's look at making an actual networking call to retrieve some data that we can use in our recipe app.

Creating our network helper

Let's start by taking a look at what data we are going to get back from our call. We'll use a publicly open API called that will generate a placeholder image for our recipe on the off chance we've not got a photo at hand.

This is a very simple API that is generated based on the structure...
