you can create an IBDesignable class and set it to your Image. Then change properties in Storyboard with realtime changes

@IBDesignable class CircularImageView: UIImageView {

@IBInspectable var borderWidth : CGFloat {
    get { layer.borderWidth }
    set {
        layer.masksToBounds = true
        layer.borderWidth = newValue
        layer.cornerRadius = frame.size.width / 2
    }
}

@IBInspectable var borderColor: UIColor? {
    set {
        guard let uiColor = newValue else { return }
        layer.borderColor = uiColor.cgColor
    }
    get {
        guard let color = layer.borderColor else { return nil }
        return UIColor(cgColor: color)
    }
}

}
