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.

Creating a Breathing App

So far, we have looked at the SwiftUI fundamentals, some of the modifiers we can use to alter a view in a certain way, and many of the properties that can be animated. Now it’s time to put that knowledge to work and build our first project.

In this chapter, we will build an animation that is similar to the breathing apps that are popular on Apple watches and iPhones. There will be three animations that we will combine to make six circle views move, recreating the slow, rhythmic motions of the Apple app.

There is not a lot of code needed to make this app work; however, as we move through the book, we will build upon this project and gradually ramp up the difficulty.

The steps needed to complete the project are as follows:

  • Setting up the project with Xcode
  • Adding the variables
  • Implementing a background color
  • Adding the circles
  • Animating the circles
