iOS: Error when updating to 3.1.0 (PageScrollAnimation)

[oblakr24]

I have a KMP project (Kotlin 2.0.0) with an iOS target.
Updating from 3.0.0 to 3.1.0 (Essenty at 2.0.0) works fine on Android and Desktop, but on iOS I get the following build failure:

error: org.jetbrains.kotlin.backend.konan.llvm.NativeCodeGeneratorException: Exception during generating code for following declaration:
Inside: FILE fqName:feature.main fileName:/Users/rokoblak/Projects/PersonaLLM/composeApp/src/commonMain/kotlin/feature/main/MainScreen.kt

This is a composable in my app which is a page in a pager.

Pages(
            pages = component.pages,
            onPageSelected = component::selectPage,
            modifier = Modifier.padding(padding).fillMaxSize(),
           scrollAnimation = PagesScrollAnimation.Default,

and is specifically related to this line:
scrollAnimation = PagesScrollAnimation.Default,
commenting out this line solves the issue.

The root stacktrace below:

What compose version are you using? Could you please try using Essenty 2.1.0 and Compose 1.6.10?

[oblakr24]

@arkivanov yep I used Essenty 2.1.0 (just tried with 2.0.0 to ensure which version bump was related to the issue).

I am using 1.6.11:

compose-plugin = "1.6.11"
jetbrainsCompose = { id = "org.jetbrains.compose", version.ref = "compose-plugin" }

[arkivanov]

Would it be possible to provide a reproducer?

[arkivanov]

This looks like a compiler bug.

[oblakr24]

I have the app here:
https://github.com/oblakr24/personallm

I am assuming the minimal reproducible scenario would be a Pager with this animation, but haven't set that up to validate.

But yes, it does seem like a compiler bug.
Perhaps related (but closed?):
JetBrains/compose-multiplatform#4809

[arkivanov]

That issue looks related, thanks! I would check a reproducer and report a bug to Compose, if you could provide a link to a runnable project with the failing changes.

[oblakr24]

I pushed the bump here:
https://github.com/oblakr24/personallm/tree/feature/decompose-to-3.1.0
the project should be runnable (no other setup needed).
I can try setting up a smaller project later (not today) with min repro scenario.

[arkivanov]

Thanks! I managed to create a minimal reproducer. Reported here: JetBrains/compose-multiplatform#4809 (comment)

Let's keep this bug open for visibility purposes.

[arkivanov]

The suggested workaround works. Add the following lines to gradle.properties.

kotlin.native.cacheKind=none
compose.kotlin.native.manageCacheKind=false

[oblakr24]

Great, thank you, the workaround works for me too. But yes let's keep it open until the related CMP issue is resolved.

[arkivanov]

Looks like this issue should be fixed in Kotlin 2.0.10, the fix is already available in Kotlin 2.0.10-RC2. See JetBrains/compose-multiplatform#4809 (comment). Closing this for now.
