React-native-firebase: Crashlytics is not reporting crash for iOS but work on android

[johnlim5847]

Issue

Hi, I'm having an issue with crashlytics for iOS. I have uploaded the dSYMs file to crashlytics on firebase but I still can't see any reporting. I recently migrated from Fabric to Firebase and I follow every step in the installation guide. However, it works on android and I'm able to crash on both iOS and Android but only Android crash logs are reported and I can't even find the build in the filter for iOS which is very strange! can anyone from the team help me with it?

Force Crash
What I called in app

  firebase.crashlytics().log('Test Message!');
  firebase.crashlytics().recordError(37, 'Test Error');
  firebase.crashlytics().crash();

iOS Version

Android Version

As you can see I can't find 1.8.5 on iOS

#2534 (comment)

Hi, thanks for your reply as I mentioned in my post there are no missing dSYM files because I have uploaded all of it manually myself(download from appstoreconnect) so I think it might be something else that I couldn't figure out.

[johnlim5847]

UPDATE
I can see the crashes in Xcode but there's nothing on Crashlytics which is very strange. Did I miss out something when I migrated from Fabric to Firebase is there a way to verify? because I can call the Crashlytics method like crash(), record() or other Firebase module without a problem so I assume it is working fine.

[mikehardy]

Definitely release mode?
Definitely restarted the app (the crashes go out when you launch next time)?
On a real device? (I think Simulator might work but I don't trust it)
🤔

Yeah, I released a build on Testflight and purposely crash the app but I still can't get any report on iOS Crashlytics but when I crash on Android I can see it on Android Crashlytics though

[johnlim5847]

For the simulator, I can see the log saying it was successfully reported but I still can't see anything

[johnlim5847]

I found out it is because of missing Fabric key because I migrated from Fabric previously and I deleted it from info.plist. Sorry for wasting your time, appreciate your help! @mikehardy

[mikehardy]

thanks for reporting back the root cause. Seems like we need a FAQ that gets all these things together in one spot since we seem to discover new failure modes about once a month

If you started a new "troubleshooting.md" page here: https://github.com/invertase/react-native-firebase/tree/master/docs/crashlytics

Patterned off this maybe https://raw.githubusercontent.com/invertase/react-native-firebase/master/docs/crashlytics/ios-setup.md

And linked it here: https://github.com/invertase/react-native-firebase/blob/master/docs/sidebar.yaml#L138

We could maybe start a list of "things to check if you can't see your crashes"

Hi @johnlim5847, Are you using react-native-firebase v6? I have the same issue. But I just followed these steps: https://github.com/invertase/react-native-firebase/blob/master/docs/crashlytics/ios-setup.md
But I cannot see any crashes on firebase dashboard. I can see the crashes on the "Organizer" window.
I have understood with "${PODS_ROOT}/Fabric/run" we don't have to add the Fabric Key in info.plist, is this correct? @mikehardy
*Note: Im migrating my app from RN0.50 to RN0.61.1.
Before I was using:
Xcode 10, RN0.50 (without pods) and react-native-firebase (5.5.5)
Now: Xcode 11, RN0.61.1 (with Pods) and react-native-firebase (6.0.0)

 "@react-native-firebase/analytics": "^6.0.0",
 "@react-native-firebase/app": "^6.0.0",
 "@react-native-firebase/crashlytics": "^6.0.0",

*I was able to see the analytics on the firebase dashboard.

Thanks!

@rodribech20 did you figure out this issue? I'm facing the same...

[johnlim5847]

@rodribech20 no I'm using v5 because my react native version is still 0.59.10.

[hiroyaiizuka]

same problem.

Android is all ok, but iOS we can't see any logs after upgrading RN 0.59 to 0.61.5.

    "@react-native-firebase/app": "^6.1.0",
    "@react-native-firebase/crashlytics": "^6.1.0",

[mikehardy]

@hiroyaiizuka try it in release mode on a real device with a forced crash, then reopen the app, wait a little bit (use the time to make sure you've got your dSYMs downloaded from apple developer and uploaded to crashlytics) then re-check

I just did this and it works

[hiroyaiizuka]

@mikehardy
Thank you for your kind comments. I'll try later! 😊

[hugocruz11]

Hello @mikehardy , I`m have the sam problem, my application does not connect, just shows

[mikehardy]

In my experience no two problems are exactly alike. For what it's worth I just spun up a new firebase ios app and mine looked like that until I actually forced a test crash on a real device on a release build then restarted the app, and I'd uploaded the dSYMs correctly. Have you triple-checked all of those steps?

[NotTooReact89]

@mikehardy there is no way for me to upload the dysm manually. i always get the "Error loading your missing dSYMs"

[mikehardy]

I strongly recommend fastlane to automate this. You have to use scripts to upload now, and fastlane knows how to fetch the dSYMs from apple and upload them to crashlytics. https://stackoverflow.com/questions/54577202/how-to-run-upload-symbols-to-upload-dsyms-as-a-part-of-xcode-build-process/55796619#55796619

[tolik85]

Building in Release mode was the key for me. Thanks!
