Unity Google Play Games Plugin Won't Compile in Xcode iOS

Question

Whenever I try to compile my Unity game in Xcode I get a 3 compile errors which are coming from the Unity Google Play Games plugin:

GPGSAchOrLbDelegate.h - Lexical or Preprocessor Issue 'GooglePlayGames/GooglePlayGames.h' file not found

GPGSRealTimeRoomDelegate.h - Lexical or Preprocessor Issue 'GooglePlayGames/GooglePlayGames.h' file not found

GPGSManager.h - Lexical or Preprocessor Issue 'GooglePlus/GooglePlayGames.h' file not found

I've no idea why this is happening, I followed all the setup instructions correctly. Any help would be greatly appreciated!

Answer 1

one gotchya is they recently changed many of the method names in the library, in a recent update...

it's possible this has caught you out?

It's very hard to resolve this, but I found some discussion about this for example here,

it's a bit easier on iOS than Android.

Alternately: note that, essentially, you have not included the GooglePlayGames.h file. Include the link to "which" instructions you were following, to guess which step is problematic. (Most Unity plugins - like Prime31 - have a "preprocessor" stage that does that for you or in the case of Android fills in the damned manifest. Something is going wrong at that stage.)
