Hello everyone, there might be an answer for this already, have been looking for an answer but haven't found anything outstanding. I integrated Firebase Crashlytics in my Compose multiplatform project. The issue is that the stacktrace it sends to crashlytics is useless, it does not contain any good reference to the Kotlin code that failed.

Have any of you faced this already and know some workaround?

[John O'Reilly]

Are you uploading dSYM files?

[John O'Reilly]

Also might need to setup https://github.com/touchlab/CrashKiOS

[Eury Perez]

@John O'Reilly yeah the dSYM files are getting uploaded. I'm taking a look at that library, thanks!

[Eury Perez]

CrashKiOS did it for me, thank you @John O'Reilly

I have a similar question, @John O'Reilly. Is that the same reason I'm unable to make sense of my Crashlytics crash as well?

Thanks. I'm also able to understand the Crashlytics logs after integrating the CrashKiOS
