Discussion
Your File Provider extension must define one or more classes that adopt the NSFileProviderEnumerator protocol. Instances of these classes must be able to enumerate both the contents of the specified item and any changes to the content.
Override this method to return an instance of your custom NSFileProviderEnumerator class for the specified item (either a document or a folder). For more information, see Content and Change Tracking.
