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.

Since you're only displaying the elements, why not take the NSSet, and call -[allObjects] on it to get a NSArray?
If your data changes, you'll have to re-fetch anyway, even with a NSSet, and apart from the initial conversion from the NSSet, using the array is quite fast.
