🔥iOS Xcode Log error "Unsupported value sent to buildTypeMap"

[noahtallen]

Issue

I ran into some build errors due to using the currently supported version of the iOS Firebase sdks (5.12?). The first issue was the google measurement API, and the second issue had to do with GRPC something or other. Both issues were resolved in recent updates to the iOS SDK, and since the build issues were.... painful... I decided to bump the SDK versions to 5.15 and hope that react-native-firebase would still support them correctly. As far as I can tell, everything in my app is working correctly, including creating documents and downloading collections, etc. However, while debugging a separate issue, I noticed the following error in my Xcode logs:

2018-12-23 20:01:45.909568-0500 zonder[60193:2894442] +[RNFirebaseFirestoreDocumentReference buildTypeMap:] [Line 328] RNFirebaseFirestore: Unsupported value sent to buildTypeMap - class type is NSNull

This error is repeated a few hundred times in a row, it seems. Not sure why. It seems to be an internal error while using the latest iOS Firebase SDK version, so I figured I'd report it as you guys prepare for version 5.2.0. ;)

Thanks for the report, looks like they changed output of nulls in Firestore on iOS, was nil before, looks like it's now NSNull instances.

https://github.com/invertase/react-native-firebase/blob/master/ios/RNFirebase/firestore/RNFirebaseFirestoreDocumentReference.m#L235

Can see our convertion there, just needs a or is kind of class NSNull adding to support it.

If anyone can do a PR that'd be helpful, otherwise I'll look at this in the new year. It's none breaking right now so no rush.

Cool! I have a bit of time, so I'll put together a PR.
