Animating SwiftUI Applications

By: Stephen DeStefano

Overview of this book

Swift and SwiftUI are the backbone of Apple application development, making them a crucial skill set to learn. Animating SwiftUI Applications focuses on the creation of stunning animations, making you proficient in this declarative language and employing a minimal code approach. In this book, you'll start by exploring the fundamentals of SwiftUI and animation, before jumping into various projects that will cement these skills in practice. You will explore some simple projects, like animating circles, creating color spectrums with hueRotation, animating individual parts of an image, as well as combining multiple views together to produce dynamic creations. The book will then transition into more advanced animation projects that employ the GeometryReader, which helps align your animations across different devices, as well as creating word and color games. Finally, you will learn how to integrate the SpriteKit framework into our SwiftUI code to create scenes with wind, fire, rain, and or snow scene, along with adding physics, gravity, collisions, and particle emitters to your animations. By the end of this book, you’ll have created a number of different animation projects, and will have gained a deep understanding of SwiftUI that can be used for your own creations.

Summary

In this project, we created the illusion of a bouquet of flowers breathing by using a collection of coding modifiers: we used blur to create the illusion of smoke, and scale and rotationEffect to make the flowers expand and contract in an arc, and we also added labels on the screen. On top of this, we used the UIViewRepresentable protocol and the CAEmitter class, and incorporated particle systems to create falling snow.

Here are some extra thoughts on how to take this app further, or just practice adding some more features, to help stretch your skills with SwiftUI animations. How about adding some sound to the project? We did that in Chapter 4 with the Record Player project, and it’s very easy to do – you could add some guided voice narration that simply says “breathe in, breathe out” or some meditative music.

Or how about adding a button or slider that will change the speed of the animation? Maybe you want to increase the petal opening and...
