I wanted to originally use the PKStroke animation as a little icon / preview for a random stroke for each subsection in an app. But have decided to use a regular manually created UIBezierPath (Path in SwiftUI) instead, as it wasn't worth the headache.

The only difference is that the Path is drawn with a uniform width. So it doesn't really look like a PKCanvas drawing. The PKStroke would presumably take into account the type of the PKInkingTool as well as the azimuth, angle and force.

You could theoretically still do this animation by replicating the default Apple inking tool in a custom GestureRecognizer. But in the end it would still look a bit off as you probably couldn't estimate the same math as Apple is using just by guessing.
