Xcode react-native Undefined symbols for architecture x86_64

After updating my RN to 0.18, I have this error that appears when trying to build my project. It comes from this package : http://github.com/magus/react-native-facebook-login

The error says : 

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_FBSDKAccessToken", referenced from:
      objc-class-ref in libRCTFBLogin.a(RCTFBLoginManager.o)
  "_OBJC_CLASS_$_FBSDKLoginButton", referenced from:
      objc-class-ref in libRCTFBLogin.a(RCTFBLogin.o)
  "_OBJC_CLASS_$_FBSDKLoginManager", referenced from:
      objc-class-ref in libRCTFBLogin.a(RCTFBLoginManager.o)
ld: symbol(s) not found for architecture x86_64

I don't really know what it means, if anyone could help me on this one..

I just set up Other Linker Flags with

-all_load

In my own experience, when using 0.40.0+ adding the -lz flag to your Other Linker Flags within the Project's Build Settings, it will allow the linker to correctly reference these from the framework.

OK, found out why. The Facebook SDK frameworks were in my project tree but not added "as" frameworks (they didn't appear in the "Linked Frameworks and Libraries").
