Refreshed Apple Pencil API Handling Input from Apple Pencil and Pencil Interactions.
Read Apple Pencil API. It has model trained on Open Images Dataset. It has traffic sign category. I should give it a try!
It’s interesting to read in [Apple Pencil at pspdfkit.com]https://pspdfkit.com/guides/ios/current/annotations/apple-pencil/
There is no simple way to know whether a device supports Apple Pencil, whether the user has one, and if it is currently connected. All an app knows is that if it receives a touch event of type UITouchTypeStylus, then an Apple Pencil was connected at that time.
But SO gives smart solution for that which I should check Stackoverflow thread Detect whether Apple Pencil is connected to an iPad Pro.
Interesting essay Apple Pencil Note-Taking: Why You Should Use Apple Notes, actually.
