```

## Discussion

The notification object is [`shared`](/documentation/AppKit/NSApplication/shared). This notification doesn’t contain a `userInfo` dictionary. The system posts this notification on the main actor.

To observe this notification using Swift concurrency, use [`NSApplication.ProtectedDataDidBecomeAvailableMessage`](/documentation/AppKit/NSApplication/ProtectedDataDidBecomeAvailableMessage).
