The mask modifier is a lesser known tool in SwiftUI where we can make objects take the shape of others. As you'll see, it becomes extremely handle when creating complex animations. In this video we will first create a basic star rating component, and then we take it to the next level by applying a mask and custom animations. During the process, we will also learn how to use .allowsHitTesting() to disable touches on certain layers of the View. The end product looks very professional and is something you can use in production applications!
