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.

Exploring animation options

In the previous section, we learned how to use implicit and explicit animations. By default, we were given a basic animation by SwiftUI, but as we saw with the easeIn option, there are many more variants to choose from.

In this section, we'll be covering all the options that are available and how to use them in our implicit and explicit animations.


The first options we are going to take a look at are easings. Probably one of the most commonly used effects of animation, easings can make even the most basic of animations look polished and finished.

Easings have been around for a while, specifically in web development within cascading style sheets (CSS).
