Objective Sharpie fails to generate binding for Gigya static library

I am STILL in the process of binding the Gigya IOS library. I was able to create the .a files and now I am stuck generating the binding using Objective Sharpie. When I was in the process of creating the .a file in xamarin, I ran into a protocol exception related to the Google Plus libraries concerning the protocol for the GPPSignInDelegate.

I added the Google Plus framework to the solution and the library was able to build successfully.

Now that I am trying to bind the libraries to C#, I am getting the error again even after I added header references to the Google + headers. Has anyone run into this before with object binding?

Here's the output:
