this seems to be related to this: https://youtrack.jetbrains.com/issue/KT-45552#focus=Comments-27-4773392.0-0

So this actually solved it: It seems to be a current limitation. To get any code that uses an iOS package dependency you need to have it part of

iosX64Main

and

iosArm64Main

source sets. You can still use other iOS actulation implementations as part of

iosMain.

As per the docs we need to define the dependencies btw source sets like this:

val iosX64Main by sourceSets.getting
        val iosArm64Main by sourceSets.getting
        val iosMain by sourceSets.creating {
            dependsOn(commonMain)
            iosX64Main.dependsOn(this)
            iosArm64Main.dependsOn(this)
        }

And instead of defining your iOS package dependency as part of

ios()

target shortcut, we need to have to split targets:

iosArm64

and

iosX64

. Before getting compiler to recognize your iOS package you need to first build the project.
