ios - Xcode 8.0 beta give an error after import Firebase

Question

I create empty swift project with Xcode 8.0 beta 5 or 6 and import Firebase with use cocoapods like Firebase guidelines. Everythings fine while import process. I configure firebase with FIRApp.Configure()comment. I can handle with Authentication but when I try to reach database it didn't work.

Build time error in FIRApp.h like :

"Conflicting nullability specifier on return types, 'nullable' conflicts with existing specifier 'non null'"

Screenshot of FIRApp.h Build-time error

Also these kind of error in the console:

2016-08-26 13:00:32.719: <FIRInstanceID/WARNING> STOP!! Will reset deviceID from memory.
2016-08-26 13:00:32.719: <FIRInstanceID/WARNING> Failed to fetch default token Error Domain=com.firebase.iid Code=6 "(null)"

2016-08-26 13:02:08.329: <FIRInstanceID/WARNING> Failed to retrieve the default GCM token after 5 retries

I couldn't solve the problem.
