## Discussion

Use this identifier with [`NotificationCenter`](/documentation/Foundation/NotificationCenter)’s `addObserver(of:for:using:)` or `messages(of:for:bufferSize:)` methods to observe messages of type [`NSBundleResourceRequest.LowDiskSpaceMessage`](/documentation/Foundation/NSBundleResourceRequest/LowDiskSpaceMessage).
