# suspended

Suspends or resumes notification delivery.

```
var suspended: Bool { get set }
```

## Parameters

`suspended`

<doc://com.apple.documentation/documentation/Swift/true> suspends notification delivery, <doc://com.apple.documentation/documentation/Swift/false> resumes it.

## Discussion

See [`DistributedNotificationCenter.SuspensionBehavior`](/documentation/Foundation/DistributedNotificationCenter/SuspensionBehavior) for details on how the receiver delivers notifications to their observers when normal notification delivery is suspended.

The <doc://com.apple.documentation/documentation/AppKit/NSApplication> class automatically suspends distributed notification delivery when the application is not active. Applications based on the Application Kit framework should let AppKit manage the suspension of notification delivery. Foundation-only programs may have occasional need to use this method.
