"Could not find service "com.apple.CoreSimulator.CoreSimulatorService" in domain ......"
The solution would be change permissions on the: /Applications/Xcode.app/Contents/Developer/Library/PrivateFrameworks/CoreSimulator.framework/Versions/A/XPCServices/com.apple.CoreSimulator.CoreSimulatorService.xpc
with:
sudo chmod g-w com.apple.CoreSimulator.CoreSimulatorService.xpc
Enjoy!
