How to sort Core Data fetched properties

Question

The Core Data Documentation states that:

The fetch request associated with the [fetched] property can have a sort ordering, and thus the fetched prope

Answer 1

Sadly, though, the ability to sort is somewhat limited. For example, you cannot take a field that is an NSString containing a number, and sort it numerically, at least not with a SQLite backing store. As long as you are sorting alphabetically on strings, numerically only on values stored as numbers and so forth, though, the NSSortDescriptor applied to the fetch request works just fine.
