Function: 

extension UIView {

    func roundCorners(corners:UIRectCorner, radius: CGFloat) {

        let path = UIBezierPath(roundedRect: self.bounds, byRoundingCorners: corners, cornerRadii: CGSize(width: radius, height: radius))

        let mask = CAShapeLayer()

        mask.path = path.cgPath

        self.layer.mask = mask

    }

}

Usage:

override func viewDidLoad() {

        super.viewDidLoad()

        self.automaticallyAdjustsScrollViewInsets = false

        Label.roundCorners(corners: [.topLeft, .bottomLeft], radius: 8)
