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.

Creating custom Views in Lists

In this section, we'll take a look at how we can create custom and re-usable views to use in our List View. It's important that we understand the value of doing this early on, as it reduces the need for code duplication; while SwiftUI's declarative syntax is visually appealing, too much code in your struct can be daunting and very unnecessary.

Creating a custom view

First, let's start by creating another custom view, which, in turn, will house our layout and logic for each row. At the bottom of the ContentView.swift file, create the following struct in the format that would create a View struct for SwiftUI:

struct RecipeView: View { 
var body: some View {

}
}
