Apologies for being vague, I really should learn to proof read
properly before pressing send.
I've sussed it out. I point the relationship attribute (wrong word I
know) at the instance of the new object.

What I can't do is set change the relationships. In my tableView

have the Transaction object update the relationship to the new
Account accordingly. Reading the core data docs I can't for the
life of me figure out how to do this. I believe I need to take the
name from the tableColumn, figure out which account it belongs to
then somehow set that as the relationship by using KVC.
The documentation explains how to manipulate relationships here:

Other than that, it's not clear what you're trying to achieve.
"I want to be able to type a new Account.name in there" -- type in
where? What transaction are you trying to update? How would you
have done this if you weren't using Core Data?
