title: After getting the array of managed objects to delete, how do I delete ALL of them in the array?
body: <p>Is iterating over the array and deleting each one (as shown in <a href="https://stackoverflow.com/questions/1077810/delete-reset-all-entries-in-core-data/1078306#1078306">Delete/Reset all entries in Core Data?</a>) really the only way? Or is there a one-line method? </p>
  
  <p>It's not that I don't want to type it, it's more of a performance concern in that I'd like to do it as efficiently as possible.</p>
