    I have the fetch request.  What I was wanting to do is to call the fetch request once with each unique value of bar, so that I could group them that way for an NSOutlineView.


You almost certainly shouldn't do that.  You should simply execute one fetch request to retrieve all the data you want, and then filter appropriately in memory.

Or change the schema to actually model the groupings you are attempting to achieve.
