Here's what happen:
The app started to crash for some users (not all) on WatchOS 6+ with the latest watch os SDK from xcode 11 and 11.1 and when i switched to PackageManager from cocoa pods
I also see some crashes related to JSONDecoder with WatchOS 5 in another place
I debugged it in all the ways i can:
Installing from Xcode to my watch -> no crash
Installing from Xcode in release config to my watch --> no crash
Installing from Appstore/Tesflight --> crashes
I have tried this too: min watch deplyment target to 6 in Testflight --> crashes
I checked the swift open source code of the crashing function and it seems that abort is called because there is a superclass missing. But i still don't know what i need to fix on my end.
The crash has to do with JSONDecoder.decode then it asks my Class to init and crashes on the:
let container = try decoder.container(keyedBy: CodingKeys.self)here's the crash log from some of my users:
