Hello, I'm trying to implement a media picker controller delegate as follows:

class MediaPickerController : MPMediaPickerControllerDelegateProtocol {
    override fun mediaPickerDidCancel(mediaPicker: MPMediaPickerController) {
    }
    override fun mediaPicker(mediaPicker: MPMediaPickerController, didPickMediaItems: MPMediaItemCollection) {
    }
}

I'm requested to implement some weird stuff tho, am I missing something?

Make sure your class extend

NSObject

that did it. thank you!
