It has quite a bit of problems in iOS, I managed to use it but I did not try that function. What error does it give? I am having problems with the disconnect function which apparently is only implemented in android, and also found that every iOS device when scanning for devices has a different UUID so you have to save different values for different users. Do you by any chance have multiple printers? At the moment I have one only and need to see if connecting to a second one without disconnecting gives an error, which in android does...

Can you please give an explanation on how you add the NSBluetoothAlwaysUsageDescription on your project? I'm facing the same issue, every time I tried to connect with the printer on iOS the app crashes.
