clip-masking uiview with CAShapeLayer and UIBezierPath

Question

I have a problem clipping a view using CAShapeLayer-UIBezierPath , I want to clip the content but I end up getting a stroke (frame) with that UIBezierPath , This is my code

You can even improve @Eugene's response (greate work, mate!) with corner radius

  extension UIView {  
    func mask(withRect rect: CGRect, cornerRadius: CGFloat = 0, inverse: Bool = false) {
        let path = cornerRadius > 0 ?
            UIBezierPath(roundedRect: rect, cornerRadius: cornerRadius) :
            UIBezierPath(rect: rect)
        let maskLayer = CAShapeLayer()

        if inverse {
            path.append(UIBezierPath(rect: bounds))
            maskLayer.fillRule = kCAFillRuleEvenOdd
        }

        maskLayer.path = path.cgPath

        self.layer.mask = maskLayer
    }
}
