Swift 5, 4

iOS 11

override func draw(_ rect: CGRect) {
  super.draw(rect)

  guard let context = UIGraphicsGetCurrentContext() else { return }

  context.saveGState()
  defer { context.restoreGState() }

  let path = UIBezierPath(
    roundedRect: rect,
    byRoundingCorners: [.topLeft, .topRight],
    cornerRadii: CGSize(width: 4, height: 4)
  )

  context.addPath(path.cgPath)
  context.closePath()

  context.setStrokeColor(UIColor.red.cgColor)
  context.strokePath()
}
