What I can't do is set change the relationships. In my tableView I'm
displaying the Account name in the toAccount and fromAccount

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?
