title: Printing NSData in Swift?
body: <p>How do you output the value of <code>NSData</code> in <strong>Swift</strong>? Is it <code>NSLog</code>, <code>print</code> or <code>println</code>?</p>
  
  <p>It seems I can just print the address of the object, and not the actual contents of it.</p>
  
  <p>Thank-you</p>
