Companion for SwiftUI documents all the SwiftUI views, shapes, protocols, scenes and property wrappers for the iOS and macOS platform. The application includes an example for each method. A great deal of them are interactive and run embedded in the app. By using the associated controls, you'll see the immediate effects it has on the views, and how the code changes to produce such results. If you would like to modify an example, with a single click, you may create and launch an Xcode Playground, or paste it in your own project. You don't know what the control point in a quad curve is? No problem, open the .addQuadCurve() entry and drag the points of the curve to see how the parameters of the function change. It's instant knowledge, that will accelerate your learning curve dramatically.
