NSFileProviderPage
A synchronization point that represents the next batch of items to be returned by an enumerator.
Declaration
struct NSFileProviderPageDiscussion
Your file provider should populate the page with the information it needs to partition items into batches and to systematically return a batch of data at a time. For example, a simple page could contain the index of the next item to return. A request to enumerate items from that page would then return a batch of items starting at the specified index.
