I am using [Player](https://github.com/piemonte/Player) library, that is using AVPlayer & AVFoundation, which is quiet convenient for my case. I successfully managed to play the video and add a slider. I set the slider's min to 0 and max to duration of the video..

At this point, in order to connect slider to current playtime, I used [this answer](https://stackoverflow.com/a/34463369/4705339), on StackOverflow. I setup a protocol and used `addPeriodicTimeObserverForInterval`, so slider is linked to the currentTime and moving as video moves along successfully.

Now, here is my problem. I want to do the reverse and make - when slider moves, set currentTime of the video (forward,backward).

I made some research and I found out that it's `seekToTime` that I should link the `slider.value` (`sender.value` in my case) but, I couldn't understand how to apply it to Player. How can I make the slider to control the currentTime?

I am not sure if I am right, but as far as I understand, the first step should be:

```
protocol UserSetsTheTimeDelegate
{
  func userSetsTheTime(result: Int)
}

class ViewController: UIViewController, PlayerDelegate {
       ...

  func sliderValueDidChange(sender:UISlider!) {
     print("value--\(sender.value)")
     self.delegate?.userSetsTheTime(sender.value)
  }
}

```

And add, I think I should add the `UserSetsTheTimeDelegate` in Player.swift, but I got confused here.

**Update**:

I realised that I can send the data to the Player.swift by using an instance in ViewController and adding a method in Player class. This is the first step. But now, as currentTime is getting updated (with modifying the slider) so quickly, it doesn't let me manipulate the slider value.
