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.

Understanding colors

Before we begin, let’s just have a quick look at colors. There are two color models that you may be familiar with, primary colors and RGB colors.

Primary colors are the basic colors from which all other colors can be derived. In traditional color theory, the primary colors are red, blue, and yellow. Primary colors are used in many different fields, such as art, printing, and graphic design.

RGB (which is short for Red, Green, and Blue) colors make up a color model in which the colors are combined to create different intensities of red, green, and blue light that can be displayed on electronic displays and devices, such as computers, TVs, phones, and tablets.

RGB colors are represented by their red, green, and blue components, each of which has a value between 0 and 255. The value 0 represents the absence of that color, while 255 represents the maximum intensity of that color. By varying the values of the RGB components, a wide range of colors can...
