The customer has a 53 stylus. I found this description about the 53: “Fifty-three supports iPads 3 or later iPad mini or later, iPad Pro (all models) iPhone 4s and above”.
The customer is using the stylus currently with his iPad. Since my app is a drawing app that needs pressure sensitivity to function, is it possible that only the Apple Pencil and Logitech Crayon have that capability with the iPad? I have looked at many brands of stylus that all claim to function on the iPad Pro for drawing and show compatibility with the major drawing apps. I am curious what code I can implement to make my app function with these third party pencils.
