title: set default Font for NSTextView with swift
body: <p>I am able to change the Font in NSTextView AFTER I have loaded some text.</p>
  
  <ul>
  <li>nameTextView.string = "Some Text"</li>
  <li>nameTextView.textStorage?.font = NSFont(name: "Lucida Sans", size: 15)</li>
  </ul>
  
  <p>but how can I set this Font as the default Font?</p>
  
  <p>if the user starts typing in an empty NsTextView control, the Font always returns to the controls default Font which seems to be 'Helvetica Regular', size 12</p>
