isDisconnected
A Boolean value indicating that the domain is present, but disconnected from the file extension.
Declaration
var isDisconnected: Bool { get }Discussion
Users can continue to browse the content from a disconnected domain; however, the File Provider extension no longer sends or receives updates about modifications to the files.
To change the disconnected state, create a new NSFileProviderDomain using the same identifier, and pass it to add(_:completionHandler:).
