I'm writing a receipts/invoice recording app.
Each receipt or invoice needs a unique # for auditing purposes.
It is great that core-data does all the joins. I was using a mysql
wrapper, but it involved so much more work to get going.

Thanks for that. It seems I will have to subclass the array
controller and put some code in there. I tried the delayed
selector calling method shown on the page, but that crashes my app.
It's a shame that there isn't an auto-inc field type in coredata.
Out of curiosity, what would you like to use an auto-incrementing
attribute for?
Core Data supports managed object IDs for your objects
automatically, eliminating the need to perform your own primary key
management. Core Data also handles relationships for you
automatically, eliminating the need to perform your own with
relationship management via foreign keys and joins.
