title: Xcode 12 using Firebase pods. Lexical or Preprocessor issue. "pb.h' file not found with <angled> include; use "quotes" instead"?
body: <p>I've just downloaded Xcode 12 beta 6. I've installed firebase into the project and I get this error. When I correct it with the suggestion it then tells me to correct again with the original. This error is repeated for all 'GoogleDataTransport'. Can you use Firebase with Xcode 12 beta 6? What am I doing wrong? Thanks</p>
