Is it possible to extend an existing Kotlin class to conform to a interface?

data class MediaItem(
    override val title: String,
    override val artist: String?
)

interface MediaItemProtocol {
    val title: String
    val artist: String?

extend AstroMediaItem: MediaItemProtocol {

}

this sort of thing is possible in swift, such as:

extension MediaItem: MediaItemProtocol { 

}

[ephemient]

no, extension interfaces are not possible

[markturnip]

so with a modular approach where by a model definition is in one package and protocol in another, that means having a third definition to bind the two?

class MediaItemWrapper(private val item: MediaItem) : MediaItemProtocol {
    override val title: String get() = item.title
    override val artist: String? get() = item.artist
}
