I'm currently playing around with Kotlin multi platform feature and have a minor problem. When I start gradle multi-platform project in Intellij and use keywords 'actual' and 'expect', they are underlined in red and show message "The feature "multi platform projects" is experimental and should be enabled explicitly"
How can I explicitly enable multi platform feature? Thanks
Finally found an answer. In Intellij in Preferences->Build, Execution, Deployment->Compiler->Kotlin Compiler append to Additional command line parameters: field command -Xmulti-platform.
