Hey, my team is completely lost on what could cause such an error when running ./gradlew iosSimulatorArm64Test

Maybe there is some sub-dependency that is misaligned such as described here? https://kotlinlang.org/docs/whatsnew19.html#library-linkage-in-kotlin-native

Logs:

Hmmm.. its probably because canvas was removed so thats why it cannot be found (https://github.com/JetBrains/compose-multiplatform-core/pull/1680) but why does it fail the tests only and still let me run the app?

[Павел Кунявский]

It fails only when you try to call removed function. If you don't call it it's fine.

[Павел Кунявский]

Are you sure that all parts of compose library are same version in your setup?

[jQrgen]

Hey thanks for the reply. What are exactly are the removed functions?

I have tried commenting everything about canvas but it doesn’t work.

This started failing in CI for JVM and iOS (the logs in the OP) when we upgraded to Compose multiplatform 1.8.0

I’m pretty sure everything is the same version. I’ll double check when I get back to the office.

Typically this error can happen in following scanario.

There is a app -> libA -> libB dependency chain. libA is using some function foo from libB , which is removed in new version of libB. If you upgrade libB but not libA you would see this error.

In your case, it looks like, that SkikoComposeUiTest.createUi is comming from older version than other parts of compose.

We had forgotten to update the project level compose dependency 🤦‍♂️
