Dashed line border around UIView

Question

How do I add dashed line border around UIView.

Something Like this

Answer 1

extension UIView{
func addDashedLineBorder() {
    let color = UIColor.black.cgColor

    let shapeLayer:CAShapeLayer = CAShapeLayer()
    let frameSize = (self.frame.size)
    let shapeRect = CGRect(x: 0, y: 0, width: self.frame.width, height: self.frame.height)

    shapeLayer.bounds = shapeRect
    shapeLayer.position = CGPoint(x: frameSize.width/2, y: frameSize.height/2)
    shapeLayer.fillColor = UIColor.clear.cgColor
    shapeLayer.strokeColor = color
    shapeLayer.lineWidth = 1
    shapeLayer.lineJoin = kCALineJoinRound
    shapeLayer.lineDashPattern = [2,2]
    shapeLayer.path = UIBezierPath(rect: shapeRect).cgPath

    self.layer.addSublayer(shapeLayer)
}

} and call this function in viewdidLoad() with delay:

DispatchQueue.main.asyncAfter(deadline: .now() + 0.5) { 
            // Your code with delay
            self.YourView.addDashedBorder()
        }
