# identifier

The name of the action group.

## Declaration

```swift
var identifier: String? { get set }
```

## Discussion

Discussion This property is a writable version of the one declared by the parent class. When generating a notification that includes these custom actions, you must use this string to initialize the notification. For local notifications, assign the string to the category property of the UILocalNotification object. For push notifications, use the string as the value of the category key in the push notification’s payload.
