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