Update the slider based on the audio Player time duration iOS Swift

First, you have to declare the updater.

Code:

    var updater : CADisplayLink! = nil

    var progress:UISlider!

Then add the target to the updater.

Code:
            updater = CADisplayLink(target: self, selector: Selector("updateProgressView"))

            updater.frameInterval = 1

            updater.add(to: RunLoop.current, forMode: RunLoopMode.defaultRunLoopMode)

Then implement the selector method.

Code:  
  func updateAudioProgressView()

    {

        if player.isPlaying

        {

            // Update progress

            

            let total = Float(player.duration/60)

            let current_time = Float(player.currentTime/60)

            progress.minimumValue = 0.0

            progress.maximumValue = Float(player.duration)

            progress.setValue(Float(player.currentTime), animated: true)            

        }

    }
