Hah! I believe Paul and Jens have identified the problem! Yes, I am
using [[Tip alloc] init]. I'll rework that portion of the code and
ping back later confirmating the good news.
Thanks guys!

I think the problem is in your creation of the Tip NSManagedObject--
you can't simply call [[Tip alloc] init] and have it work. Create
your object via "[[NSManagedObject alloc] initWithEntity:@"Tip"
insertIntoManagedObjectContext:[self managedObjectContext]]" or
"[NSEntityDescription entityForName:@"Tip" inManagedObjectContext:
[self managedObjectContext]]" and it should work as expected.

My guess would be that you're not instantiating the object properly.
NSManagedObject does some very, very weird stuff behind the scenes,
including swizzling in fake superclasses. Accordingly, you have to
let the CoreData factory methods instantiate managed objects: just
calling alloc+init won't work.
