iOS sim clear data between test cases


I am trying to reset/clear my app after each test case and have been unable to do so.
I have tried the full reset option in the GUI and that doesn’t seem to do anything.
Also noticed that during driver.quit() following warning pop up:
warn: Applications directory /Users/username/Library/Developer/CoreSimulator/Devices/device uuid/data/Containers/Bundle/Application doesn’t exist. Have you run this simulator before?
info: Couldn’t find app directories to delete. Probably it’s not installed
