Set the corner radius to topLeft and topRight to UIView iOS swift

Solution:

Add function to layoutsubviews to your view..Set the top left and right corners to the view roundTopCorners...

    override func layoutSubviews() {

        super.layoutSubviews()

        roundTopCorners(corners: [.topLeft, .topRight], radius: 3.0)

    }

extension UIView {

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

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

        let masking = CAShapeLayer()

        masking.path = path.cgPath

        layer.mask = masking

    }

}
