Unity 5.3 MFI Controller Warnings

Hi,

I'm running Unity 5.3 building for 64-bit iOS and getting the following warnings spammed to the console if I have an MFI controller connected. I'm using a MOGA Rebel.

Warning - conversion from 64 bit to 32 bit integral value requested within NSPortCoder, but the 64 bit value

I've searched and have found a few references to the warning, but no answers. Is there any workaround for this?

Thanks!
