Are there any guides for debugging iOS kmp / compose multiplatform stack traces? I don't quite know where to begin. I had an app work on iOS, and after bumping a few libraries and moving to kotlin 2.1, I get a crash on start up.

Exception Type:  EXC_CRASH (SIGABRT)
Exception Codes: 0x0000000000000000, 0x0000000000000000
Termination Reason: SIGNAL 6 Abort trap: 6
Terminating Process: heron [64521]

I'm not sure how to start investigating the kotlin cause if there's one. (edited)

I think this is where you would start + with Fleet you may debug iOS builds -> https://crashkios.touchlab.co/docs/misc/THE_PROBLEM

Thanks so much!

[Tunji Dahunsi]

Using fleet helped, thanks again!

Fleet is so slow and mostly unusable for me
