How to listen AVPlayer "on seek" events?

Question

I'm looking for any "seek"-related events for AVPlayer/AVPlayerItem/AVAsset

Is there any way to listen such events? (maybe some key for kvo-listeners, not sure)

Answer 1

It seems there is a workaround with KVO (please tell me if it's wrong decision):

case "currentItem.playbackBufferEmpty":
    if (player.rate == 0) {
        state = "SEEKING"
        on_seeking()
    }
case "currentItem.status":
    if (player.currentItem?.status == .ReadyToPlay && player.rate == 0) {
        if (state != "SEEKING") {
            on_seeking()
        }

        state = "SEEKED"
        on_seeked()
    }
