There may be some technical limitations that prevent UI Test from clearing everything on iOS when running UI Tests on a local device, but UI Test should at least clear what it can. Indeed UI Test used to clear files from the app's library folder; we were able to use that as a trigger for clearing other settings on app init. But we no longer have that capability with the latest versions of UI Test. Please have AppDataMode.Clear clear what it can when running on a local iOS device. Ideally it would also clear NSUserDefaults settings.
