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 confetti using Swift packages

A Swift package is pre-built software that we can use in any of our projects, in which all the coding work has been done for us; all we have to do is configure it in our project.

To add a Swift package, in Xcode, go to the File menu and select Add Packages…:

Figure 14.11: Add Packages…

In the All Sources window, enter https://github.com/simibac/ConfettiSwiftUI.git in the search box:

Figure 14.12: Adding the URL

When the Add Package button is clicked, Xcode will add the Confetti package to the project. The Confetti package contains all the code needed to create all kinds of confetti, dispersed in different ways.

Now, we need to import the Confetti framework into the ContentView file at the top:

import ConfettiSwiftUI

Next, we need a variable that can trigger the confetti (placed after the other project variables):

//confetti variable
    @State var...
