Is there something like associated types in Swift in Kotlin? The problem I’m facing is that I need create instances of enums that satisfy a certain interface. Those enums have an associated value, e.g. Monday(1), Tuesday(2), etc.

So from 1 I need to get a Monday instance. I understand that a factory can be declared as a companion object. But then I need to set a requirement for a certain companion object in the interface that that enum implements. Otherwise I cannot come up with a generic solution.

Any ideas?
