I successfully disabled this functionality by not setting the visibility of the PKToolPicker. This only works since I don't use its UI, because I build an overlay: toolPicker.setVisible(Environment.isDebugMode, forFirstResponder: UIView())

Hey I had a similar Problem, sadly there is no API from Apple which makes this easy. I solved it by manually adding an UIImageView into the canvas aka. scrollView. So in the end you have to handle everything by yourself, when it comes to dragging or scaling the image view.

Hey, in iOS 15 Beta there was an even worse bug, where you could not change the PencilKit Tool programatically. It was fixed in the final release. I have also sent a bug report and it says: potential fix with iOS 16. I am confident that this will be fixed in the final version, so don't worry. If you want some feedback you can use your Technical Support Incident (TSI) and request some insight, which I did back in the days for the other bug.

I don't this is possible yet. Seems like they have sadly limited this functionality to their own apps...

I have the same problem on the latest Xcode Beta, one interesting thing though: the bug happens on iOS 17.2 but not on 17.4. Maybe I will change the target version. I really hope this bug is not shipped into production as I will submit my Swift Students Challenge app tomorrow... Fingers Crossed :)

I’ve noticed many apps that have won, and they all require a camera. My app will also need a camera, and I’m certain that if it requires a camera or other hardware capabilities, it will be tested on real hardware.

For me this crashes: let session = LanguageModelSession() but this does not: let session = LanguageModelSession(instructions: "Some Instructions") Devices: MacBook Pro in Sequoia 15.6, Xcode 26 Beta 4, iPad Pro iOS 26 Beta 6
