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.

Animating pipe smoke

In this project, we will create a smoke effect using SpriteKit’s Smoke template, and make it come out of an image of a pipe. This is a good first project, as it’s not too complicated and gets you familiar with creating the needed SpriteKit Scene (SKS) particle file and how to configure it.

Let’s get started, first create a new SwiftUI project, and call it Pipe Smoke. We are going to need a couple of images for this project so you can grab them over at GitHub (Chapter 15 | Pipe Smoke) and add them to the project’s Assets catalog. Now it’s time to create a SpriteKit particle file.

Creating a SpriteKit particle file

Next, let’s create a new file; this will be a SpriteKit particle file. The SpriteKit Scene (SKS) particle file is a scene file that has information about the particle system it contains, such as the shape, size, and position of the particle emitter, as well as the type of particles that will be emitted...
