In this final chapter of the book, we learned some techniques that can be used to create amazing visual results that are similar to the special effects in films. For this purpose, we had a look at how we can create particle systems, either by using the editor available in Xcode, or programmatically so that we can modify its properties to improve our game performance.
We learned how to combine SpriteKit and UIKit to make use of the potential that game elements have in applications. Vice versa, we also learned how to use typical app elements to create robust games.
In the last half of the chapter, we developed some skills so that we can create our own audio resources and customized text fonts. We had a look at some places where we can find free and paid music files on the Internet that can be included in our games. Finally, we had a look at where we can find amazing visual content, such as sprites, textures, backgrounds, and visual elements, on different websites.
