I have implemented the code below with nothing else. In the init()

Nothing is called.
I have also tried to ctrl-drag a link in IB from the text boxes to the
AppController class and connect 'delegate'.
I guess this is a stupid question: where am I going wrong?
The objects are nil, and any message sent to a nil object is discarded.
IBOutlets aren't connected at init time; they're connected when the nib
is instantiated. If your class implements the method -awakeFromNib,
then that method will be called when the instantiation process is done.
Also, text fields use a different set of delegate methods than the ones
you're trying to use; look at the documentation for NSControl to see
the methods you should implement.
