Intellij? Very likely, unless the plan is to only do that in Appcode and/or Clion. It works now it Appcode, but you need to jump through hoops. That’s all config, though. lldb GUI debugging works. You can debug iOS Kotlin code in Xcode if running in a simulator. We run some of our tests from Xcode/XCtest which means they’re also debuggable (
https://github.com/touchlab/DroidconKotlin/blob/master/sessionize/lib/src/iosTest/kotlin/co/touchlab/sessionize/KotlinTestStarter.kt). In theory you could attach Xcode to the test exe, but I’ve never done that. Summary, it’s possible in Xcode today, but painful. It works in Appcode, although I’m not sure how you’d open a KN project in Appcode. All the pieces work, so it’s a matter of time before they get included in Intellij (barring other product driven plans)
