Set cornerRadius separately bottom-left,bottom-right and top-left,top-right corner of a UIView?

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:
YourView.roundCorners([.topLeft, .bottomLeft], radius: 10)
