MidiTest demo in iOS target doesnt see any MIDI devices

in the demo sample app Miditest - When trapping a breakpoint in updateDeviceList() in the OSX version I can see the devices connected to my mac.

However when i run the iOS simulator - the same code compiled for iOS sees none oy my MIDI keyboards and other MIDI devices. IS there something one has to do to “fool” the iOS simulator into recognising the MIDI devices connected to my mac running Xcode so the iOS app thinks the iPad is seeing the MIDI devices as directly connected to IT too ?

Otherwise i cannot see how i could debug MIDI stuff in the simulator.
