# init(dateMatching:repeats:)

Creates a calendar trigger using the date components parameter.

```
convenience init(dateMatching dateComponents: DateComponents, repeats: Bool)
```

## Parameters

`dateComponents`

The temporal information to use when constructing the trigger. Provide only the date components that are relevant for your trigger.

`repeats`

Specify <doc://com.apple.documentation/documentation/Swift/false> to deliver the notification one time. Specify <doc://com.apple.documentation/documentation/Swift/true> to reschedule the notification request each time the system delivers the notification.

## Return Value

A new calendar trigger based on the specified temporal information.

## Discussion

If you specify `true` for the `repeats` parameter, you must explicitly remove the notification request to stop the delivery of the associated notification. Use the methods of [`UNUserNotificationCenter`](/documentation/UserNotifications/UNUserNotificationCenter) to remove notification requests that are no longer needed.
