How to add padding to left right view in UITextField

extension UITextField {
    func setLeftView(_ view: UIView, padding: CGFloat) {
        view.translatesAutoresizingMaskIntoConstraints = true

        let outerView = UIView()
        outerView.translatesAutoresizingMaskIntoConstraints = false
        outerView.addSubview(view)

        outerView.frame = CGRect(
            origin: .zero,
            size: CGSize(
                width: view.frame.size.width + padding,
                height: view.frame.size.height + padding
            )
        )

        view.center = CGPoint(
            x: outerView.bounds.size.width / 2,
            y: outerView.bounds.size.height / 2
        )

        leftView = outerView
    }
}
