Adding a inner border bottom to a subclass of UiView in swift4

Question

I want to add an inner border bottom to one of the subclass(custom) of UIView , I am looking if there is an extension for the UIview . Thanks in advance.

Answer 1

extension UIView {
    func customBorder(){
        let borderWidth: CGFloat = 0.84
        self.frame = frame.insetBy(dx: -borderWidth, dy: -borderWidth)
        self.layer.borderColor = UIColor.white.cgColor
        self.layer.borderWidth = borderWidth
        self.clipsToBounds = true
    }
}
