Getting Unsupported URL error on LoginKit and Firebase Auth iOS

[tyegah]

Without firebase, the snapchat LoginKit is working normally, but with firebase it always returns unsupported URL error.

Here's the error log:
Error Domain=SCSDKLoginKitFirebaseErrorDomain Code=2 \"unsupported URL\" UserInfo={NSUnderlyingError=0x283da9860 {Error Domain=kCFErrorDomainCFNetwork Code=-1002 \"(null)\"}, _NSURLErrorFailingURLSessionTaskErrorKey=LocalDataTask <E361B52B-75F9-4708-94F9-F924F1E9A754>.<1>, _NSURLErrorRelatedURLSessionTaskErrorKey=(\n \"LocalDataTask <E361B52B-75F9-4708-94F9-F924F1E9A754>.<1>\"\n), NSLocalizedDescription=unsupported URL}

The errors and the documentations are not helping at all when trying to solve an issue. And I'm looking at other issues here, it seems the Snapchat developer don't really give a damn about the issues.
