Did anyone had same problem and know how to fix it with Xamarin IOS?
Error MT5214: Native linking failed, undefined symbol: _GPGUserDidSignOutNotification. This symbol was referenced by the managed member Google.Play.GameServices.Manager.DidSignOutNotification. Please verify that all the necessary frameworks have been referenced and native libraries linked. (MT5214)
Seems like the Google component binding has a P/Invoke to a function that doesn't exist in the native library => Components.
It seems that _GPGUserDidSignOutNotification symbol is still defined on gpg library for some reason:
$ nm -Um gpg | grep GPGUserDidSignOutNotification
0000000000008c40 (__DATA,__const) external _GPGUserDidSignOutNotification
but I can't find it defined nowhere within GPG's headers.
DidSignOutNotification will be removed from binding.
Fixed on version 188.8.131.52
