The Checkbox offers a binary choice.
The Checkbox is used as any other view.
The component has two mechanisms for notify when the value changes. You can use the onValueChanged close
checkbox.onValueChanged = { checked in
// do something
}or using the target-action pattern of UIControl. Checkbox only send actions for UIControl.Event.valueChanged,
checkbox.addTarget(self, action: #selector(checkboxTapped), for: .valueChanged)
