I have a relatively complex SwiftUI app that seems to occasionally crash with the typical unhelpful EXC_BREAKPOINT reason. I thought, no big deal, I'll just try to reproduce it in Xcode which would allow me to see the problem line of code. To my shock, Xcode spit out a really long stack trace too, and highlighted the @main line without any clue as to what's actually causing the crash. Sentry logs are of no help, and users and I failed to consistently reproduce the crash.
My app is a Discord chat client and is open source here if anyone would like to take a look at it. The crash is inconsistent, and occurs sometimes after running for a long time, when a channel is changed a few times or sometimes immediately after loading messages.
And here are relevant logs to the crash, if they could shed some light on the issue
Some Xcode screenshots:
Here's what Sentry has to say, which is more unhelpful than it usually is
Could someone please give me some clues on how I could start debugging this problem? It has been plaguing the app since a couple of versions ago and seems to be rather persistent. From what I have gathered, this is potentially an issue deeply rooted in SwiftUI itself.
