Skip Particular Intro

[karanwhizcamp]

Let Suppose, I've add 5 instructions on the screen but in some cases Some Views will hide but the Intro Show on that side. so I want to show only intro's which views are visible.

extension ViewController: CoachMarksControllerDataSource {
    // MARK: - Protocol Conformance | CoachMarksControllerDataSource
    func numberOfCoachMarks(for coachMarksController: CoachMarksController) -> Int {
        return 4
    }

  func coachMarksController(_ coachMarksController: CoachMarksController, coachMarkAt index: Int) -> CoachMark {

      let flatCutoutPathMaker = { (frame: CGRect) -> UIBezierPath in
          return UIBezierPath(rect: frame)
      }

      var coachMark: CoachMark
      switch index {
      case 0:
          coachMark = coachMarksController.helper.makeCoachMark(for: self.scheduleIntro)
          coachMark.arrowOrientation = .top
      case 1:
          coachMark = coachMarksController.helper.makeCoachMark(for: self.motivationVideoIntro)
          coachMark.arrowOrientation = .bottom
      case 2:
          coachMark = coachMarksController.helper.makeCoachMark(for: self.videoIntro)
          coachMark.arrowOrientation = .top
      case 3:
          coachMark = coachMarksController.helper.makeCoachMark(for: self.missionView)
          coachMark.arrowOrientation = .bottom
      default:
          coachMark = coachMarksController.helper.makeCoachMark()
      }
      coachMark.gapBetweenCoachMarkAndCutoutPath = 0
      return coachMark
  }

  ) -> (bodyView: (UIView & CoachMarkBodyView), arrowView: (UIView & CoachMarkArrowView)?) {

      let coachMarkBodyView = CustomCoachMarkBodyView()
      var coachMarkArrowView: CustomCoachMarkArrowView?
