It seems that the directory for the iOS Simulator has changed. It used to be in ~/Library/Application\\ Support/iPhone\\ Simulator/ and now it\'s in ~/Lib
~/Library/Application\\ Support/iPhone\\ Simulator/
~/Lib
To me, this is what worked.
I did same thing as we do in device.
I have to do this on 3 simulator instances, as XCUI automation testing can spin 3.
