Bytecode stripper fails for iOS builds no matter what. Unity 5 Plus. Mac OSX.

I get the following any time I include Photon SDK (1.75 via Unity Asset store) in any project, even a blank one with nothing in it but PUN Demo Hub. Unless fixed I cannot use Photon for anything.

I am on Mac OS X El Capitan with Xcode 8 and Unity 5 Plus.

Thanks,
