title: Connecting an NSTextField object to an IBOutlet in AppDelegate.swift
body: <p>Recently, I've been trying to learn Swift, so if this seems to be a relatively simple question do forgive me.</p>
  
  <p>For some reason, control-clicking a NSTextField object in a tab view controller and dragging doesn't give me the option to "insert outlet or action" but rather, "connect binding" when I scroll over a compatible object (in this case it was the superclass declaration).</p>
  
  <p>Why is it that I am not able to insert an outlet or an action, but am able to connect a binding?</p>
  
  <p><em>side question: what is a binding?</em></p>
