title: How do I know what COLUMN my cursor is at in Xcode?
body: <p>Sometimes I want to know what column my cursor is at, so I can see how many characters I have left til the print margin.</p>
  
  <p>This is a common functionality in most IDEs and text editors, but I couldn't find it in Xcode.</p>
  
  <p>Is it possible to enable this or see it somewhere?</p>
