            let view = UIView(frame: CGRect(x: 0, y: 0, width: 50, height: 50))
            view.backgroundColor = UIColor.gray
            views.append(view)
        }
        
        pickerView.firstselectedItem = 2 // you can also set the first selected item at launch 

    }
    func didSelectIndex(index: Int) {
