How to display an NSSet in a UITableView?

How would you proceed to display the content of an NSSet in a UITableView?

As you know, the table view will ask for the element at a given row, but since the NSSet elements aren't ordered, this doesn't mix well.

My current solution is to iterate through the NSSet until I reach the element at a given index, but this really doesn't feel right.

You may ask why I don't use an NSArray instead. This is because I'm using Core Data, which uses NSSets to store collection of elements.

Any help would be appreciated.
