Answer 1

Looks like you have a lingering connection to a no-longer-existent outlet. Perhaps you deleted a textField that you previously set up?

Ctrl-/right-click on the File's Owner in the Xcode editor, look for a warning triangle. Clear that out (by deleting the connection or re-connecting it to the proper outlet) and you'll likely be good.
