Don't see any reason why Kotlin reflection shouldn't work. Java for sure won't.

I haven't used Kotlin reflection much yet due to it's very large library

Kotlin Reflection on JVM back-end is (probably) based on Java reflection and annotations like @Metadata, but Kotlin-native Reflection can't have anything in common with Java reflection.

Yes, there will be completely separate implementation for native. I would expect all the APIs we can use on JVM will be available, except of course

.javaClass

,

::class.java

and similar stuff.
