I've upgraded my Compose Multiplatform (Android + iOS + Desktop) project from Kotlin 2.1.0-Beta1 to Kotlin-2.1.0-Beta2 and now I'm getting the following error when building the app to run on iOS Simulator:

Undefined symbols for architecture arm64:
  "_kfun:androidx.lifecycle.viewmodel.compose#access$<get-androidx_lifecycle_viewmodel_compose_LocalViewModelStoreOwner$stable>$p$tLocalViewModelStoreOwnerKt(){}kotlin.Int", referenced from:

      ...
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Android and Desktop builds are working fine.

I'm using the following related multiplatform frameworks/libraries:
• jetbrains compose: "1.7.0-rc01"
• jetbrains lifecycle and viewmodel: "2.8.2"
• jetbrains navigation compose: "2.8.0-alpha10"
• koin: 4.0.0
I'll appreciate if someone can help.

@arnaud.giuliani Not sure if this is a Koin+ViewModel+Lifecycle issue, but looks like it's happening with ViewModels, and I'm injecting them with koinViewModel() .

[arnaud.giuliani]

ok, interesting feedback. I need to confirm that on my side too. Did you see anything from the lifecycle KMP lib, in terms of issue?

[Armond Avanes]

I can't find any further details. That's the only error message that I see.

I've bumped up against the exact same issue, with much the same dependency load-out:

• org.jetbrains.compose version 1.7.0
◦ compose-gradle-plugin
• org.jetbrains.androidx.lifecycle version 2.8.3
◦ lifecycle-runtime-compose
◦ lifecycle-viewmodel-compose
• org.jetbrains.androidx.navigation version 2.8.0-alpha10
◦ navigation-compose
• io.insert-koin version 4.0.0
◦ koin-core
◦ koin-android
◦ koin-androidx-compose
◦ koin-compose
◦ koin-compose-viewmodel
◦ koin-test
I've found that using Kotlin 2.1.0-Beta1 and KSP 2.1.0-Beta1-1.0.25 works without an issue, but bumping up to Kotlin 2.1.0-Beta2 and KSP 2.1.0-Beta2-1.0.25 causes my project to consistently throw:

ok intersting

[Tom Larcher]

Just in case it helps - I've just tested with KSP 2.1.0-Beta2-1.0.26 , and the issue persists.

[Nicolas Frenay]

I'm facing the same problem and created an issue: https://youtrack.jetbrains.com/issue/KT-72490

[Armond Avanes]

Upgrading to Kotlin 2.1.0-RC fixed this issue for me!

[Tom Larcher]

I was about to ask if the appropriate KSP release was out, to go with Kotlin 2.1.0-RC, and it seems it came out ~50 minutes ago! Damn you’re fast @Armond Avanes!

Thanks for testing and confirming you got past the issue with this latest release! kodee happy

[arnaud.giuliani]

cool 🙂

[Tom Larcher]

I can confirm that it's definitely resolved these initial issues on my side also, however I'm dealing with something new, now! 🙂

Strange build errors relating to ComposeExtension not existing. Never a dull moment 😛
