The object that provides the item data for the combo box.
Declaration
unowned(unsafe) var dataSource: (any NSComboBoxDataSource)? { get set }Discussion
Assigning an object to this property does not automatically set the usesDataSource property to true. If the usesDataSource property is false, accessing this property logs a warning. The default value of this property is nil.
