I must say that core data itself is easy, conceptually, having
worked with Rails and ActiveRecord.
It's Bindings in particular that always seems to stump me.
Conceptually, Bindings are quite simple. Practically, quite
difficult if you just don't know what object you should be binding
to where!
Quite the rabbit hole.
I bet I'm not alone in that I would pay well if somebody would
publish a Bindings cookbook or just a really lengthy book of
tutorials and various exercises using Bindings in many ways.
The thing that worries me most about Bindings though, is the same
thing that worries me about Objective-C 2.0 Properties;
neither one has great debugging options that I can see...
I agree with you about the frustrating obscurity, but I find this
often helpful:
If you've never visited this document before, you'll find it's also
maddeningly light on details, but you can often glean useful
information about what specific bindings mean, and what the
surrounding assumptions are.
Unfortunately, this document isn't linked directly by any Cocoa class
reference documentation, so it's kind of hard to get to within Xcode.
