Hi folks, I’m doing a PoC, trying to refactor a Android module to KMM to integrate in the iOS app.
We are using Kotlin 1.7,10, I did enable the Expertimental Memory Management but any kotlin object allocation seems to crash the iOS app.

iOS stacktrace and more information in the 🧵

#0 kotlin:mm:AllocateArray(kotlin:mm:ThreadData*, TypeInfo const*, unsigned int, ObjHeader**) ()
#2 Kotlin_ObjCExport_refFromObjC ()
#3 objc2kotlin.3101 at /<compiler-generated>:1
#6 Swift file and line that tries to instanciate a data class

Our gradle properties

kotlin.native.binary.memoryModel=experimental
kotlin.native.binary.freezing=disabled
kotlin.native.cacheKind=none

The project is being exported as XCFramework using the new kotlinArtifacts DSL.

[svyatoslav.scherbina]

Hi. Well, that is clearly not enough to give any meaningful advice.
Could you please provide assembly listings of frames 0-3, including the exact position in the listings?

[SrSouza]

I was exporting the XCFramework to iOS with isStatic = true, seems that was the issue.
This is expected @svyatoslav.scherbina?

[svyatoslav.scherbina]

Do you use this XCFramework in multiple modules of your project? Is one of them a dynamic library/framework?

[SrSouza]

Yes! But the usage for isStatic = true was not soemthing that I really need, is something that I configured that way without knowing.
The integration did work, pretty happy with the result K

Great, thank you for letting me know!
