Detecting touches on a UISlider?

Question

I have a UISlider on screen, and I need to be able to detect when the user stops touching it. (so I can fade some elements away).

I have tried using:

I couldn't get anything to capture both the start and end of the touches, but upon RTFD-ing, I came up with something that will do both.

  @IBAction func sliderAction(_ sender: UISlider, forEvent event: UIEvent) {

    if let touchEvent = event.allTouches?.first {
      switch touchEvent.phase {
      case .began:
        print("touches began")
        sliderTouchBegan()
      case .ended:
        print("touches ended")
        sliderTouchEnded()
      default:
        delegate?.sliderValueUpdated(sender.value)
      }
    }
  }

sliderTouchBegan() and sliderTouchEnded() are just methods I wrote that handle animations when the touch begins and when it ends. If it's not a begin or end, it's a default and the slider value updates.
