A message the system sends when it detects the amount of available disk space getting low.
After receiving this notification, your app should release any on-demand resources that aren't required.
Call ``NSBundleResourceRequest/endAccessingResources()`` to release the managed resources.
If the app is in the background and the app doesn't free up enough space, the system may terminate the app.
Observe this message with the identifier ``NotificationCenter/MessageIdentifier/lowDiskSpace``, or specify its type directly to the `addObserver(of:for:using:)` method.
The ``NotificationCenter/MainActorMessage/Subject`` of this message type is ``NSBundleResourceRequest``.
This message interoperates with the notification ``NSNotification/Name/NSBundleResourceRequestLowDiskSpace``.
The system notifies observers of the message when the ``NotificationCenter`` posts the notification.
Similarly, the system notifies observers of the notification when it posts the message.
Converts a posted notification into this asynchronous message type for any observers.
To implement this method in your own `AsyncMessage` conformance, retrieve values from the ``Notification``'s ``Notification/userInfo`` and set them as properties on the message.
- Parameter notification: The posted ``Notification``.
- Returns: The converted `AsyncMessage`, or `nil` if conversion is not possible.
