When you call [anArrayController selection] for an Entity-backed
NSArrayController, you always get an instance of
_NSControllerObjectProxy back. Even when there is no object
selected. It's not until you send a message to that proxy that you
get unrecognized selector error.

I have a bundle wit the CFBundleIdentifier set using the form
com.mycompany.myapp.mybundle. When I run mdls against it, the
kMDItemContentType shows "dyn.ah62d4qmuhk2x42pxsv3g825bsu". I
thought it was supposed to show the com.mycompany.myapp.mybundle.
Any idea why this is?

In my iOS app, I had a single primary view controller. This controlled

However, as the code grew, refactored this into three view controllers, as the

Yes, CoreData is a database, and it does do ORM. It's not just an ORM, and
it's not an RDBMS.
If it wasn't a database, it couldn't store data; that is the definition of a
database. A database is not something that has row, columns, etc; it's
something that stores data in an unspecified manor.

None. It only declares the integer to be 32-bit on 32-bit builds,
