Failing to update to 2.0.0 because of Firebase dependencies

[arpwal]

Hey folks,

I'm seeing the following issues while upgrading the library from 1.2.12

      Firebase/Crashlytics was resolved to 8.3.0, which depends on
        FirebaseCrashlytics (~> 8.3.0) was resolved to 8.3.0, which depends on
          PromisesObjC (~> 1.2)

and

      Firebase/Auth was resolved to 8.3.0, which depends on
        FirebaseAuth (~> 8.3.0) was resolved to 8.3.0, which depends on
          GoogleUtilities/Environment (~> 7.4) was resolved to 7.5.0, which depends on
            PromisesObjC (< 3.0, >= 1.2)

Is there something that I'm missing?
