Missing Argument for parameter ‘coder’ in call

Question

I have coded a custom UIButton as :

 class AccountOpeningButton: UIButton {
  required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        ......
   }
}

I am able to instantiate this Class successfully using my Storyboard. Now, i made a UIView & want to add this button in my UIView as :

var customView:UIView = UIView()
customView.frame = CGRect(x: 0, y: 0, width: 350, height: 250)
.....
let fromDateBtn:UIButton = AccountOpeningButton()//Error comes here as  : Missing Argument for parameter ‘coder’ in call
customView.addSubview(fromDateBtn)

So please help in in reusing this code dynamically also.

P.S. : I referred http://napora.org/nscoder-and-swift-initialization/ Fatal error: use of unimplemented initializer 'init(coder:)' for class Class does not implement its superclass's required members But didn't succeed.

======================================================================= TRIED

let fromDateBtn:UIButton = UIButton() as! AccountOpeningButton

This throws CastException Could not cast value of type 'UIButton' to '.AccountOpeningButton'

Replace This line

let fromDateBtn:UIButton = AccountOpeningButton()

With This:

let fromDateBtn = AccountOpeningButton()

And add this method in your class

override init(frame: CGRect) {
        super.init(frame: frame)
    }

You can have more than one init method, but you have to obey the inheritance and hierarchy rules. And you need to definitely understand what are called convenience initializers.
