Swift - label updates with SwiftRangeSlider

Question

I am trying to work with SwiftRangeSlider implemented by BrianCorbin: https://github.com/BrianCorbin/SwiftRangeSlider

@IBOutlet weak var labelForRangeSlider: UILabel!

@IBOutlet weak var rangeSlider: RangeSlider!

@IBOutlet weak var submitButton: UIButton!

override func viewDidLayoutSubviews() {
    rangeSlider.updateLayerFrames()
}
...

And this shows:

I want to update "Time", which is labelForRangeSlider, as rangeSlider's lowerValue and upperValue change.

You are supposed to add action for the event .valueChanged for SwiftRangeSlider:

override func viewDidLoad() {

   super.viewDidLoad()

   let rangeSlider: RangeSlider = RangeSlider(frame: CGRect(x: 0, y: 0, width: 200, height: 60))
   rangeSlider.addTarget(self, action: #selector(self.rangeSliderValueChanged(slider:)), for: UIControlEvents.valueChanged)
   self.view.addSubview(rangeSlider)
}


@IBAction func rangeSliderValueChanged(slider: RangeSlider) {
    print(slider.lowerValue)
}
