In terms of iOS:

fun checkInt(value:Int): String = "number: $value"

It works. when you print(checkInt(6)) at the swift side, it will print number: 6

But this won’t work

fun <T> checkGeneric(value: T):String = when (value) {
          is String -> "string"
          is Int -> "number"
          is Boolean -> "boolean"
          else -> "Unknown"
  }

String and Boolean type works fine, but print(checkGeneric(6)) will output Unknown. So, the generic is partially supported?

For debug just try to write else -> "Unknown ${value::class}"

Thanks for the trick, but seems KN compiler has a problem with the null. It says value has a nullable type T, need to make sure it is not null. Adding !! won’t work, same error 😄

But T is nullable

[gildor]

use

fun <T : Any> checkGeneric(value: T):String

to make it non-nullable

Thanks, it works now!
