hardcode solution if your Xcode still works anomaly, so, it was only partial solution to show inline errors, but if you want your normal Xcode back: move to bin your xcode, For a complete removal of Xcode delete the following: /Applications/Xcode.app ~/Library/Caches/com.apple.dt.Xcode ~/Library/Developer ~/Library/MobileDevice ~/Library/Preferences/com.apple.dt.Xcode.plist /Library/Preferences/com.apple.dt.Xcode.plist /System/Library/Receipts/com.apple.pkg.XcodeExtensionSupport.bom /System/Library/Receipts/com.apple.pkg.XcodeExtensionSupport.plist /System/Library/Receipts/com.apple.pkg.XcodeSystemResources.bom /System/Library/Receipts/com.apple.pkg.XcodeSystemResources.plist /private/var/db/receipts/com.apple.pkg.Xcode.bom But instead of 11, open up /private/var/in the Finder and search for "Xcode" to see all the 'dna' left behind... and selectively clean that out too. I would post the pathnames but they will include randomized folder names which will not be the same from my Mac to yours. And, just to double check: xcrun simctl delete unavailable xcrun simctl shutdown all && xcrun simctl erase all sudo /Developer/Library/uninstall-devtools --mode=all rm -rf ~/Library/*/CoreSimulator sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService sudo rm -rf ~/Library/Caches/com.apple.dt.Xcode install XCode again, if there is lefted simulators, on manage run destinations : remove all simulators, and install again, looks long but no issues after it :relieved: issues usually appears after updating Xcode from 13 to 15/14, espessialy if you used filter on issue navigator, looks like incompatibility of versions or so
