Using the new mpp plugin, if I have an expected declaration in the commonMain module, and have an ios and iosSim target, no matter what I try, the IDE tells me I have to have actual declarations in both source sets. Even if I do something like:

configure(targets.iosSim) {
            compilations.main.source(sourceSets.iosMain)
        }

Is there any way around this?

You can try this trick: https://github.com/JetBrains/kotlin-mpp-example/blob/master/greeting/build.gradle#L39-L47

That will work for now. Should I file this as a bug?

No, thanks, we know it…
