The Core Data Documentation states that:
The fetch request associated with the [fetched] property can have a sort ordering, and thus the fetched property may be ordered.
How do I specify the sort descriptors for the fetched property in Xcode's data model editor? I can't find a relevant field anywhere. I'm developing for the iPhone platform, if this makes any difference.
If this is not possible via the graphical model editor, how do I go about modifying the fetch request for the fetched property in code so that it has a sort descriptor?
The modeling tool doesn't appear to have a way to set the sort descriptors on the fetch request.
It should be possible[1] to, after loading the model but before associating it with a persistent store coordinator, to find the fetched property descriptions for which you want to control the sort order, and replace their fetch requests with fetch requests that have sort descriptors set on them.
[1] In principle this should work. In practice, I have not done so or tested it.
