- Make sure that the iOS simulator is not running, and close it if it is.
- In case multiple real devices are connected to the device, it is not possible at the current time to specify which real device to use (this can only be run as a batch from the command line, using this method). Only connect one real device to the Mac.
- If you are certain that there is only one device connected, confirm that the Mac is not wirelessly connected to a separate real device using the wireless debug function. You can confirm whether there are any real devices connected wirelessly using this procedure.
