        let screenSize = UIScreen.main.bounds
        let heightValue = screenSize.size.height / 2
        self.view.layoutIfNeeded()
        UIView.animate(withDuration: 1.0, delay: 0, usingSpringWithDamping: 1.0, initialSpringVelocity: 1.0, options: UIView.AnimationOptions.curveEaseIn, animations: {
            self.notchBottomConstraint.constant = -heightValue
            self.heightConstraint.constant =  heightValue
            self.view.layoutIfNeeded()
        }, completion: nil)
