How to access Kotlin’s `hashCode` and `equals` methods from shared’s code interface in Swift?

In KMM application in shared module I have interface, let’s say it’s marker interface without any actual fields

interface Marker

In Kotlin I can use equals and hashCode on instances of that interface

fun isEqual(o1: Marker, o2: Marker): Boolean {
    return o1 == o2
}

How I can do same thing in iosApp Swift code?

func isEqual(o1: shared.Marker, o2: shared.Marker): Bool {
    // todo implement
}

I tried to invoke equals and hashCode methods on instances on Swift, but I got the error, that this methods don’t exist

>Solution :

Kotlin Native convert interfaces to Swift protocols. But methods equals, hashCode and toString are provided by kotlin.Any abstract class. These methods converts to NSObject’s method isEquals(_:) and the properties hash, description in Swift. Take a look at documentation for more details.

So basically you can implement what you want using cast to NSObject

func isEqual(o1: shared.Marker, o2: shared.Marker): Bool {
    return (o1 as! NSObject).isEquals(o2 as! NSObject)
}
