# accessibilityActionDescription(_:)

Returns a localized description of the specified action.

```
func accessibilityActionDescription(_ action: NSAccessibility.Action) -> String?
```

## Parameters

`action`

The action attribute.

## Return Value

The description of the specified action, in a localized string.

## Discussion

User interface classes must implement this method to return descriptions for all actions returned from [`accessibilityActionNames()`](/documentation/ObjectiveC/NSObject-swift.class/accessibilityActionNames()). A button, for example, might return the string “press” for the `NSAccessibilityPressAction` action. Subclasses should invoke the superclass’s implementation, if it exists, to obtain the descriptions of any inherited actions.
