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 an Ocean Scene

In this chapter, we will be creating an ocean scene. To do that, we will be revisiting the Shape protocol and path function that we used in the previous project to create the waves, as well as a new SwiftUI property called animatableData, which will help to make our curvy lines animate in a fluid wave-like motion.

We will also add an image of a buoy to our scene and animate it in multiple different ways, including moving it along an anchor point, rotating it around the center of this point, and making it rise up and down along the y-axis – so the buoy looks like it’s bobbing in the water.

Finally, we will add some sound effects to the project to help it really come alive.

In this chapter, we will cover the following topics:

  • Adding the wave’s offset property
  • Creating a wave shape using the Shape protocol and Path function
  • Adding the wave’s animatableData property
  • Setting up the ContentView for animation...
