has anyone successfully built the new native memory management model? I've updated kotlin versions, but now end up with build errors around variants

Could not determine the dependencies of task ':shared:linkPodDebugFrameworkIosX64'.
> Could not resolve all task dependencies for configuration ':shared:iosX64CompileKlibraries'.
  > Could not resolve project :core:arch.
   Required by:
     project :shared

:shared is my main KMM module, corearch is another module with interface definitions and my "CFlow" implementation

[Peter Hsu]

this was compiling against kotlin 1.5.30/coroutines-core1.5.30 mt/ktor1.6.3, but I've updated to kotlin 1.6.0-M1-139/coroutines-core1.5.1 new mm dev2/ktor1.6.2-native-mm-eap-196

I'm not sure about specific errors you're seeing but if it helps I was able to try using it in following branch https://github.com/joreilly/MortyComposeKMM/tree/new_kotlinnative_memorymodel

[Peter Hsu]

cool, thanks, i'll poke around at your build files

[John O'Reilly]

this was commit with the changes I made (a little complicated by fact that I'm using different Kotlin version for Compose Android app (which still needs 1.5.21) and the iOS app) https://github.com/joreilly/MortyComposeKMM/commit/65355fd01abb13164f87364c8b91cb93f9b91bed
