That's not really necessary. Just break on the error in the debugger and type
"po [error userInfo]" to print the results of sending the -userInfo message to
the error.

That means that you added three keys to the model _and_ marked them as
required, and then the application failed to fill each of those keys with a
value prior to saving. Either you need to make the app fill those keys with
values, or you need to re-evaluate whether or not those keys should be required
to be filled & change the model accordingly.
