Answer 1

In my case, the following code works Swift 3:

var timeObserver: Any?
override func viewDidLoad() {
    ........
    let interval = CMTime(seconds: 0.05, preferredTimescale: CMTimeScale(NSEC_PER_SEC))
    timeObserver = avPlayer.addPeriodicTimeObserver(forInterval: interval, queue: DispatchQueue.main, using: { elapsedTime in
            self.updateSlider(elapsedTime: elapsedTime)     
        })
}

func updateSlider(elapsedTime: CMTime) {
    let playerDuration = playerItemDuration()
    if CMTIME_IS_INVALID(playerDuration) {
        seekSlider.minimumValue = 0.0
        return
    }
    let duration = Float(CMTimeGetSeconds(playerDuration))
    if duration.isFinite && duration > 0 {
        seekSlider.minimumValue = 0.0
        seekSlider.maximumValue = duration
        let time = Float(CMTimeGetSeconds(elapsedTime))
        seekSlider.setValue(time, animated: true)  
    }
}

private func playerItemDuration() -> CMTime {
    let thePlayerItem = avPlayer.currentItem
    if thePlayerItem?.status == .readyToPlay {
        return thePlayerItem!.duration
    }
    return kCMTimeInvalid
}

override func viewDidDisappear(_ animated: Bool) {
    super.viewDidDisappear(animated)
    avPlayer.removeTimeObserver(timeObserver!)   
}
