Here is an extension for iOS 11+

 import Foundation
 import UIKit

 extension UIView {

   func roundCorners(_ corners: CACornerMask, radius: CGFloat, borderColor: UIColor, borderWidth: CGFloat) {
       self.layer.maskedCorners = corners
       self.layer.cornerRadius = radius
       self.layer.borderWidth = borderWidth
       self.layer.borderColor = borderColor.cgColor

   }

 }

Usage:-

self.yourView.roundCorners([.layerMaxXMaxYCorner, .layerMaxXMinYCorner], radius: 20.0, borderColor: UIColor.green, borderWidth: 1)
