I've been experimenting with HID emulation on iOS (I have a Teensy board, not a Ducky) and have found that the problems may be more to do with the adapters themselves. There are lots of unofficial adapters not licensed by apple.
Has anyone tried the official Apple adapter on their iPad?
I tried out the ducky with the official USB to 30 pin adapter and it gives the same error, but does work if you dismiss it. If you put a DELAY 2000 at the beginning of the script it gives enough time for you to dismiss the error and have the rest of the script execute.
