One Minutes Tutorial of IBDesignable IBInspectable

@IBInspectable can be applied to variable/properties of a custom view and will allow you to check and update the value in Attributes Inspector





However it will not update when you change the value until you add @IBDesignable to the CustomView class. Quit Xcode completely and reopen it, if it is not rendered in real time.
