After using the new project template in IntelliJ the JVM/Android builds without issue but attempting to compile the iOS results in error "no such module app".

Known issue, will be fixed in 1.3.30. https://youtrack.jetbrains.com/issue/KT-29804

Great thx. Is there any working skeleton examples can clone from?

Sure, lots of. For example, one of them is linked from comments to the issue. Alternatively, you can take a look at https://github.com/jonnyzzz/kotlin-mpp-mobile https://github.com/JetBrains/kotlin-mpp-example

I have opened this issue. I’ve created a working solution here: https://github.com/Danilo-Araujo-Silva/kotlin-multiplatform-android-ios-example
