title: Swift iOS doesRelativeDateFormatting have different values besides "Today" and "Yesterday"?
body: <p>I have a number of dates that I am trying to represent using a relative date such as "Today, Yesterday, 1 week ago, 1 month ago" etc...</p>
  
  <p>This is the Swift code I am using:</p>
  
  <pre><code>let dateFormatter = NSDateFormatter()
  dateFormatter.dateStyle = .MediumStyle
  dateFormatter.doesRelativeDateFormatting = true
  let uploadDate = dateFormatter.stringFromDate(date)
  </code></pre>
  
  <p>Only "Today" and "Yesterday" are represented and the rest of the dates appear like the below:
  Nov 24, 2014
  Nov 17, 2014
  etc...</p>
  
  <p>Is there another way to represent all the dates using relative dating instead of the actual dates?</p>
