Is there a notification you can listen to, if the value you get here changes?

For instance will the value become false, if the user rejects the camera permission?

This api invokes system internal camera API and it seems that is will not ask users for camera permission..

Here is demo code. I didn't request any permission

Without the capability of monitoring the results of this canPerformAction: call I think it would be better to implement this feature in a way that's similar to paste: introduce an API that allows the developer to query whether live text is currently enabled on the platform, otherwise they may get outdated value?

Ah I thought you could still turn camera access off in Settings? (don't have a test device available atm, I'll give this a try tomorrow)

Yeah if you disable camera access in Settings -> Screen Time -> Content & Privacy Restrictions -> Allowed Apps, the text edit menu item will be gone.
