Since iOS 8 was released the default device type for simulator became iPhone 6. And even if I manually change the device type using Hardware > Device menu, on the next launch (using rake simulator) the simulator will revert to iPhone 6.
I wonder if there is any rake options, or some other settings to force the device type.
PS. I know that there are ways to force a non-retina iPhone and a way to launch the iPad simulator instead …
