Swift implement setter without getter

How do you implement setter without getter in Swift? I need to call a method when the value is set:

var selectedIndex : Int{
    set {
        selectItemAtIndex(newValue)
    }
}

but in Swift, you are required to use both getter and setter, not just one.

You can use the property observer didSet. This will be called immediately after setting the value. 

var selectedIndex: Int {
  didSet {
    selectItemAtIndex(selectedIndex)
  }
}
