init(frame :  CGRect ,title : String, recordUrl : String  , content : String) {
    self.title = title
    self.recordUrl = recordUrl
    self.content = content
    super.init(frame: frame)
 }

In swift, you should init your parameter first, and then implement super.Method()

This does not appear to work anymore. This throws an error like this: "self' used in property access 'title' before 'self.init' call" – rantanplan Oct 23 '18 at 04:06
