is it some known issue or i am doing something wrong?

Which command are you executing? Which version of K/N are you using? Did you compile it from sources, automatically downloaded with gradle or manually from GitHub?

../gradlew compileKonan

in the

common/slideparser-ios

folder, version of KN 0.6 .. I downloaded that from here https://github.com/JetBrains/kotlin-native/releases
