Is it possible to write a data class in a Kotlin Multiplatform library that, when built for macOS, conforms to Equatable (or better yet, Identifiable) out of the box?

[Sam]

Those are Swift only protocols and cannot be implemented in Kotlin or ObjectiveC.

I believe you can write a Swift extension for Kotlin's Any? and delegate to equals . Does it work for you @Julio Zynger?

AFAIK for Identifiable you just need a field named id in your data class. Then you can simply add Identifiable Swift extension to the Kotlin data class.

data class Data(val id: String)

extension Data : Identifiable {
}

I have a sample here.
