NSMetadataQueryAccessibleUbiquitousExternalDocumentsScope

Search for documents outside the app’s container. This search can locate iCloud documents that the user previously opened using a document picker view controller. This lets your app access the documents again without requiring direct user interaction. The result’s Nsmetadataitemurlkey attributes return security-scoped NSURLs. For more information on working with security-scoped URLs, see Nsurl in Nsurl.
