A lovely extension to reuse Yunus Nedim Mehel solution

Swift 2.3

extension UIView {
func roundCornersWithLayerMask(cornerRadii: CGFloat, corners: UIRectCorner) {
    let path = UIBezierPath(roundedRect: bounds,
                            byRoundingCorners: corners,
                            cornerRadii: CGSize(width: cornerRadii, height: cornerRadii))
    let maskLayer = CAShapeLayer()
    maskLayer.path = path.CGPath
    layer.mask = maskLayer
} }

Usage

let view = UIView()
view.roundCornersWithLayerMask(10,[.TopLeft,.TopRight])
