# deliveryRepeatInterval

Specifies the date components that control how often a user notification is repeated.

## Declaration

```swift
var deliveryRepeatInterval: DateComponents? { get set }
```

## Discussion

Discussion This value may be nil if the notification should not repeat. The date component values are relative to the date the notification was delivered. If the calendar value of the deliveryRepeatInterval is nil, the current calendar is used to calculate the repeat interval. For example, if a notification should repeat every hour, set the hour property of the deliveryRepeatInterval to 1. This value is ignored unless the user notification is scheduled with the NSUserNotificationCenter object.
