It's *a* correct approach.
It's not clear what went wrong with '[employeeController remove: nil]', but
that's a completely separate problem. For example, if you left the array
controller in Class mode rather than Entity mode, 'remove:' won't update Core
Data properly. Also, take a look at the class reference documentation for
NSArrayController (for the 'removeObject:' method) for a discussion of how to
configure the array controller's deletion behavior for Core Data.
