I have a similar issues running my app on simulator iOS 18.0. My app works fine on devices running ios17. I can't test on devices on iOS 18 just yet... (don't have access to such a device yet).

I have similar logs on iOS 17 simulator: [UIKeyboardImpl] Unsupported action selector setShiftStatesNeededInDestination:autoShifted:shiftLocked: [UIKeyboardImpl] Unsupported action selector setShiftStatesNeededInDestination:autoShifted:shiftLocked: [UIKeyboardImpl] Unsupported action selector clearKeyboardSnapshot [UIKeyboardImpl] Unsupported action selector setShiftStatesNeededInDestination:autoShifted:shiftLocked: [UIKeyboardImpl] Unsupported action selector setShiftStatesNeededInDestination:autoShifted:shiftLocked: this happens when a textfield becomes first responder - and the normal keyboard replaces my custom keyboard. It also happens when I rotate the device whilst the textfield is focused. But it does not cause any issues so far.

Ok... I think I may know why it's happening: One report is from the build the other one is from the "Show live issues" option (Preferences -> General) Disabling "Show live issues" removes one occurence of the report. I had this option off previously; I guess when I installed the new XCode this option got reset (or I reset it by mistake); but I don't recall seeing this problem in previous XCode versions...? You can also filter out "Show only issues from the lastest build" (this will only filter in the Navigator, not in the Editor)
