# notificationIdentifiers

The notification identifiers to locate in your search.

## Declaration

```swift
var notificationIdentifiers: [String]? { get }
```

## Discussion

Discussion When this property contains one or more NSString objects, your search should return UNNotification objects whose IDs match the specified strings. The UNNotificationRequest object, which is part of the notification, stores the notification’s identifier. You can use these identifiers to search your app’s delivered local and remote notifications. The value of the notificationIdentifiersOperator property determines whether searches should be for all, some, or none of the specified notification identifiers.
