HW kbd Failed to set (null) as keyboard focus ios

Question

In my iOS app crash log I found this statement:

HW kbd Failed to set (null) as keyboard focus ios 

Does anyone know what this is and how to resolve it?

Answer 1

I've just encountered this exception running a Xamarin app on the simulator. It started occurring after I toggled the software keyboard off while debugging the app. Given the exception mentioning the keyboard I think that's what caused it.

Uninstalling the app from the emulator, cleaning and rebuilding fixed the issue for me.

Unsure if this bug is on Apple's side or Xamarin's.
