Getting these 2 errors when using the KMP code from xcode. Not sure if they're related.
Can anyone help me understand what's wrong?

2023-12-03 19:35:53.013087+0530 App[21470:10960419] [error] CoreData: One or more models in this application are using transformable properties with transformer names that are either unset, or set to NSKeyedUnarchiveFromDataTransformerName. Please switch to using "NSSecureUnarchiveFromData" or a subclass of NSSecureUnarchiveFromDataTransformer instead. At some point, Core Data will default to using "NSSecureUnarchiveFromData" w"JCAnalytics: myFunction(profileId:uId:) SomeSwiftFile.swift"

For 2, we've added unhandledExceptionHook which reduced the number of crashes, but still happening. No idea what's 1.
Using the settings Multiplatform by @russhwolf, and sqldelight, if that helps.
Data classes are mutable (has var field).

Not yet on Kotlin 1.9

Wrt. 2, there's apparently an exception thrown in SDKProvider.init(), if it is your code, have you debugged what throws in there? If possible at all, fixing the root cause would be better than adding unhandledExceptionHook...

[Jan Holešovský]

Wrt. 1, hard to help without the actual source code I guess; but either way, looks like a swift & iOS error, so not sure this channel is the right place to ask about this.

[rivu.chakraborty]

@Jan Holešovský, wrt 2, yes, it's our code. The thing is it's not reproducible, so not able to debug.
The code inside init is just starting koin and saving some variables in run time memory. Nothing else.

1. Also points out to the KMP SDK
