CocoaPods could not find compatible versions for pod "GoogleDataTransport"

Issue

When adding @react-native-firebase/crashlytics@8.1.2, I first added @react-native-firebase/app@8.2.0. The app built correctly (or at least built) on both iOS and Android after adding app. However, I tried adding crashlytics, and the pod install step failed:

[!] CocoaPods could not find compatible versions for pod "GoogleDataTransport":
  In snapshot (Podfile.lock):
    GoogleDataTransport (= 7.0.0, ~> 7.0)

  In Podfile:

You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * changed the constraints of dependency `GoogleDataTransport` inside your development pod `RNFBCrashlytics`.
   You should run `pod update GoogleDataTransport` to apply changes you've made.

But running pod update GoogleDataTransport gives me this error:

[!] CocoaPods could not find compatible versions for pod "GoogleDataTransport":

        FirebaseCrashlytics (~> 4.2.0) was resolved to 4.2.0, which depends on
          GoogleDataTransport (~> 6.1)

It looks like RNFBApp and RNFBCrashlytics depend on different versions of GoogleDataTransport. My next step is to try to downgrade app to 8.1.0 and see if that works.

Downgrading @react-native-firebase/app to 8.0.1 and @react-native-firebase/crashlytics to 8.0.3 gets around this issue, but obviously it would be nice to be able to be up-to-date.

Hm so both of those versions were before the SDK version bump of #3881.
But (according to the change logs here and here), there's been no other native changes since then; and this isn't a problem I've faced (and I use

"@react-native-firebase/crashlytics@^8.0.1":
  version "8.1.1"

and

"@react-native-firebase/app@^8.0.0":
  version "8.1.0"

So, I suspect this is a local environmental issue. Have you tried completely deleting your Podfile.lock and pod installing from scratch?

[sharc7]

I faced the same issue with
"@react-native-firebase/app": "^8.2.0"
"@react-native-firebase/crashlytics": "^8.1.2"
Solved this by removing Podfile.lock and running pod install again as suggested by @andersonaddo.

[andersonaddo]

Yeah, just what I suspected.
I faced a similar problem (with a similar solution) myself when I upgraded to the version with the SDK version bump.

[ahwatts]

Yeah, I guess CocoaPods picked FirebaseCoreDiagnostics (1.5.0) when I installed the App package, and I guess that messed up Crashlytics. Updating both and then re-creating Podfile.lock appears to pick version 1.4.0 of FirebaseCoreDiagnostics which fixed this for me. Thanks!
