I have just tried to update an example multiplatform project to 1.2.0-alpha01-dev741 and Kotlin 1.7.10 (1.7.0 is the same) from dev-731 and Kotlin 1.6.21 and get the following error message when I build for iOS

java.lang.IllegalStateException: IrBasedSimpleFunctionDescriptor: FUN name:DataTooltipArea visibility:public modality:FINAL <> (dataString:kotlin.String, modifier:androidx.compose.ui.Modifier, content:kotlin.Function2<androidx.compose.runtime.Composer, kotlin.Int, kotlin.Unit>) returnType:kotlin.Unit [expect]

The project builds and runs perfectly on JVM and even on Web (Canvas). Can anybody tell me what this error message actually means?

It looks like a compose bug. I suggest you to ask in #compose or report them an issue

[Michael Paus]

I did that originally but they sent me here 😢 Will create an issue.

[dmitriy.novozhilov]

It also can be a compiler bug, but I bet that's on compose plugin side

I got the same issue with expect actual on compose fun

Maybe you should then vote for the issue or add a comment to it.

Sure, I just did that hope it will be fixed soon.
