Hi guys,
anyone who could bring me a little bit light into understanding firebase crashlytics on iOS / CrashKiOS?

[Jiri Bruchanov]

I'm just testing it and don't understand one thing. Is firebase somehow do extra processing of the stacktrace ?
Or am I doing some stupid mistake in configuration/setup ?

Just throwing manually an exception to kill the app.
Crashlytics console

So can't asy anywhere my ViewModel, so trying to investigate it more. Generating my own NSException manually with the stack addresses and result is exactly same.

However if I try to symobilacte stacktraces address manually. I get exactly what I'm looking for

kfun:kotlin.Throwable#<init>(kotlin.String?){} (in DrivikoDev) (Throwable.kt:30)
kfun:kotlin.Exception#<init>(kotlin.String?){} (in DrivikoDev) (Exceptions.kt:23)

What am I missing here ? Why the firebase crashlytics doesn't show me the stacktrace I'm looking for and I'm able to recover manually from exactly same NSException ?
