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.

Adding a background

First, the background. You can find the resource for this project in the Chapter 14 folder on GitHub (it’s the only asset in the folder); just drag and drop the background image file into the Asset Catalog. After you’ve done that, add the following code in ContentView, after the closing brace of the main VStack, like this:

.background(Image("background").resizable().edgesIgnoringSa
  feArea(.all))

Here, we are using the background modifier, passing the name of the image, resizing it, and setting edgesIgnoringSafeArea to stretch it out throughout the whole screen. It’s a subtle background, but it has a nice pattern to it that I think works as a backdrop for the colorful UI:

Now, let’s look at Swift packages, and how to make some confetti.
