title: Using the new Core Data Batch Updates, is it possible to batch delete?
body: <p>My current method of deleting all of a certain kind of object in Core Data is to <a href="https://stackoverflow.com/a/1383645/998117">iterate over each object and delete manually</a>, which is rather expensive.</p>
  
  <p>Using the <a href="http://matthewmorey.com/core-data-batch-updates/" rel="nofollow noreferrer">new batch updates</a> added to Core Data this year, can it be accomplished like that?</p>
