How to unobfuscate / symbolize the ios stacks produced

[defiantgoat]

My ios stack traces in crashlytics look like below

I can't find any library that helps me map these to a sourcemap, etc. I've looked at stack-beautifier and also https://reactnative.dev/docs/next/symbolication.

Novice here with stack traces like this and crashlytics. Are these how the logs should look?

I see references in to your index.bundle there, you should be able to unwind those first to your minified bundle, then (assuming you kept the map from pre-minified-bundle to post-minified-bundle, back to source ?
