In the recent WWDC 2022, FreeForm app was introduced and in that app in the tool picker there was a Fill Tool. I want to put that fill tool (or any similar filling tool) in my xcode app that I am building. But when I use pencilkit PKToolPicker, there is not Fill Tool. So how to get this fill tool in my app. Any leads would be helpful. Thanks.

Hi, can i create custom tool for PKToolPicker? On documentation page on PKTool says "Don’t adopt this protocol in your own objects. Instead, create a tool object to provide users with the desired the tool behavior." Best regards, Matej Klemen

on iOS, I want to add up undo/redo and a close button. On ipadOS, I only need to add a close button What’s your experience in adding a close button to the ToolPicker? Or at least have the position of the window so I can add an overlapping box (even on floating).

There are use cases where someone who's using an Apple Pencil may not want to enter text via Scribble. A simple example is writing "UIViewController" in a text view is unlikely to be successful. I'd like to disable Scribble in this case and let the keyboard become the input mechanism. (Disabling Scribble system-wide in Settings is both cumbersome and overkill.) The closest I can come to making this happen is by adding a UIScribbleInteraction on a UITextView and returning false when scribbleInteraction(shouldBeginAt:) is called. This disables Scribble on the text view, and prevents writing from being converted into text, but the input widget still appears on screen and isn't very useful. Here is a sample project that demonstrates the problem: http://files.iconfactory.net/craig/bugs/Scribbler.zip Hopefully, I'm doing something wrong here. If not, I'm happy to submit this as a FB. -ch

Hey guys, Is there a native bridge between a PKStrokePath and other path objects like CGPath, UIBezierPath or even SwiftUI Path ?
