I’m getting an error when building for the iOS simulator on Mac M1 (detailed logs attached in the thread). Originally the iOS build of my shared library is complained target ios_simulator_arm64 is missing. When I added 
iosSimulatorArm64()
as a target to my build.gradle.kts, then the build complains that my “expect” classes are missing for that target with: 
Expected class 'SettingsStorage' has no actual declaration in module <shared> for Native.
What is the proper way to get around this error and build for the simulator?

Kotlin Multiplatform Projects are an Alpha feature. See: <https://kotlinlang.org/docs/reference/evolution/components-stability.html>. To hide this message, add 'kotlin.mpp.stability.nowarn=true' to the Gradle properties.

Dependency on pods requires cocoapods-generate plugin to be installed.
If you plan to add dependencies on third party pods, don't forget to install it by executing 'gem install cocoapods-generate' in terminal.

Please wait while Kotlin/Native compiler 1.6.10 is being installed.

Unpack Kotlin/Native compiler to /Users/m/.konan/kotlin-native-prebuilt-macos-aarch64-1.6.10 finished, took 17 s 303 ms

The following Kotlin source sets were configured but not added to any Kotlin compilation:
 * androidAndroidTestBeta
 * androidAndroidTestRelease
You can add a source set to a target's compilation by connecting it with the compilation's default source set using 'dependsOn'.

Hello. You have to make iosSimulatorArm64 depends on iOS target such as (in sourceSet block): 
val iosSimulatorArm64Main by getting { dependsOn(iosMain) }
Same goes for iosTest target
r
Thanks, now I’m getting a new error!

Oh ? which one ?
