Thanks to an off-list reply from an Apple Engineer, I now know
that one of the example apps answers my question and a host of
related questions. For those interested, the link is below:
http://developer.apple.com/samplecode/CoreRecipes/CoreRecipes.html
With regards to the CoreRecipes example, I have to make some
comments. The Hands-on examples are too elementary, but good for what
they are. The real meat though is in CoreRecipesApp. The data model
is much more elaborate than in the hands-on examples, all of the
entities are subclasses of a custom subclass of NSManagedObject,
there are at least 3-6 classes related to the creation of the smart
groups etc...
It illustrates a lot of stuff, but I have to admit it's quite a
sudden change from the hands-on examples. I would be invaluable to me
at least if someone who understands the ins and outs of it could
write a walkthrough of the app, what all the classes do and why it is
necessary for them to be there. I would do it myself, in fact
eventually I will, but it will certainly take me a while to figure it
out, and I certainly don't know the ins and outs of it. The comments
in the docs are pretty helpful found, but I would have liked a lot
more detailed explanations, and a smoother jump between the hands-on
examples and the full-fledged app.
Ok, to be fair, a lot of my problem is around understanding how the
smartGroups mechanism there works. Maybe there is another place where
the general mechanism for creating smartGroups and the whole UI
associated with them is explained (i.e. how to create a similar UI
like in the predicate editor, and the backend to support that UI)?
I'd love to see a detailed explanation of that.
Anyway, my $0.02.
