How to get _appdelegate an arrayController from viewController ? ?

Hi,
in the past, before apple killed opengl, I had access to the arrayController via outlet.
Because most samples from the internet use storyboard, me too.
I use a splitViewController with a source- and and a displayViewController.
I moved the notificationCenter and the tableView notification "selectionDidChange" to the sourceViewController.
Bindings are established.
Adding a new row I get my managedObject, but it is empty 😝.
I see the merit of storyboard but I'm ready to turn back to XIB.
