Can't run RealTimeRoom Google-Play-Games iOS ButtonClicker2000 sample on real device

Question

I'm trying to run Google-Play-Games iOS sample ButtonClicker2000 project on Real Device. (quickstart: https://developers.google.com/games/services/ios/quickstart
downloads: https://developers.google.com/games/services/downloads/)

1. The process of signing in to GooglePlayService does not show any error.
   
2. I'm sure that my google console project setted up correctly.
   
3. I don't have any problem when launching on emulator
   

BUT on a real device (it doesn't matter on iphone or ipad) when i click on quick match button i get this error (at the bottom):

How can i fix this bug? Any help is really appreciated

Answer 1

Eventually i've found working solution for this issue. I don't know when exactly but google's guys added "objective c" headers for C++ SDK. These headers are kind of bindings for C++. So the C++ SDK became drag-and-dropable.
