AVPlayerItemDidPlayToEndTime never reaches selector on Swift 3
<p>I'm adapting my app to Swift 3 and I'm encountering this problem. This used to work on Swift 2.2 but now it's broken. moviePlayBackFinished never gets called. I tried adding the observer in multiple ways, all without success.</p>

<pre><code>    NotificationCenter.default.addObserver(self, selector: #selector(self.moviePlayBackFinished(_:)),
                                           name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: player.currentItem);

    NotificationCenter.default.addObserver(self, selector: #selector(moviePlayBackFinished(_:)),
                                           name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: player.currentItem);

    NotificationCenter.default.addObserver(self, selector: #selector(self.moviePlayBackFinished(sender:)),
                                           name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: player.currentItem);

// (...)

@objc func moviePlayBackFinished(sender : AnyObject) {
    print("playbackFinished");
    let zeroCM : CMTime = CMTime(seconds: 0, preferredTimescale: 1000000000);
    playerLayer.player?.seek(to: zeroCM);
}

@objc func moviePlayBackFinished(_ notification: Notification) {
    print("playbackFinished");
    let zeroCM : CMTime = CMTime(seconds: 0, preferredTimescale: 1000000000);
    playerLayer.player?.seek(to: zeroCM);
}
</code></pre>

<p>Any ideas would be appriciated.</p>

<p>Thank you</p>
