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 Colorful Kaleidoscope Effects

In this chapter, we will look at how we can animate colors with a modifier called hueRotation, where “hue” refers to the colors of the object, and “rotation” refers to the colors being rotated or animated. We will create a simple project that displays various images and then, using hueRotation, we can change or shift the colors of the images so that they will resemble somewhat of a kaleidoscope effect.

Along with hueRotation, there are some other important concepts we will explore in this project.

We will work with a Picker view for the first time, which is exactly what the name suggests; it lets the user pick from a variety of options, which can then be displayed on the screen.

Also, we will look at how to pass data bidirectionally to another view. If you remember the moving circle project in Chapter 3, it was built inside one file and then within one view, the ContentView. In Chapter 4, we built the record...
