static let removalRequested: MTLDeviceNotificationName
```

## Discussion

This notification tells your app to stop using an [`MTLDevice`](/documentation/Metal/MTLDevice) instance by releasing any objects and resources your app created with it.

> Note:
> Metal removes the device instance from the array it returns with its methods — such as ``doc://com.apple.metal/documentation/Metal/MTLCopyAllDevices()`` — before sending this notification.
