Adding GooglePlayGames API To Xcode Results In Multiple Architecture I386 Errors

So I'm trying to add Google Play Games into my app, but I'm struggling to get their sample code to work. I've seen this issue mentioned a couple times on stack overflow, but I have yet to find a definitive answer.

I'm following the manual instructions listed here: https://developers.google.com/games/services/ios/quickstart

and adding them to the buttonclicker code here: https://github.com/playgameservices/ios-basic-samples

What results is a 32 Undefined symbols for architecture i386 errors like the ones below.

Undefined symbols for architecture i386:

      _OBJC_CLASS_$_GTLGamesAchievementUpdateResponse in gpg(GTLGamesAchievementUpdateResponse.o)
      _OBJC_CLASS_$_GTLGamesCategory in gpg(GTLGamesCategory.o)

I've added the GoogleSignIn.framework, gpg.bunde, and gbg.framework to the project.

I searched for some of these (like GTLCollectionObject) and could not find where it is referenced in the project.

I've tried it on a device, tried removing the 64-bit architecture, and a host of other things, but I'm stuck at 32 errors. What am I missing with this set up?

You need to add the GoogleOpenSource.framework as well.

This is covered in steps 3 and 4 of https://developers.google.com/games/services/ios/quickstart#option_2_manual_installation

• Download and extract the latest Goservices/ios/quickstart#option_2_manual_installation" >https://developers.google.com/games/services/ios/quickstart#option_2_manual_installation
  • Download and extract the latest Google+ iOS SDK from the Google+ Downloads page.
  • Copy the following items from the Google+ SDK into your project: GoogleOpenSource.framework

  Just out of curiosity, why no use Cocoapods? It does a great job of adding the required frameworks to the project without all the hassle of downloading from multiple sites and then copying them into the project.
