Declaration
func asynchronousMetadataFlush() throwsDiscussion
This method schedules a flush of data previously written with delayedMetadataWriteFrom:startingAt:length:error: to the resource and returns immediately without blocking. This method doesn’t wait to check the flush’s status. If an error prevents the flush from being scheduled, the error is indicated by the in-out error parameter.
