Received this today while using the Xcode Simulator iOS device and cycling through keyboards. Specifically, the notification that showed up on the system Ventura 13.4.1 (22F82): Privacy & Security "SimulatorTrampoline.xpc" was prevented from modifying apps on your Mac. App was not special, simple login screen with a single text field. Simulator device was iPhone SE (3rd gen) -- iOS 16.4. Keyboards were English (email), Japanese Kana, and emoji. (App was launched via homescreen not Xcode)
