title: Adding new line to NSCharacterSet
body: <p>I want to strip a string of all new lines and commas (and place it into an array), so I created this:</p>
  
  <pre><code>let results = text.componentsSeparatedByCharactersInSet(NSCharacterSet(charactersInString: ",\n"))
  </code></pre>
  
  <p>However, the newlines are still existing in my array (the commas are being removed). What's the correct way of adding newline to the NSCharacterSet? Or, how to add comma to NSCharacterSet.newLineCharacterSet.</p>
  
  <p>Thanks.</p>
  
  <p>Here is janky solution, but still looking for a more elegant one.</p>
  
  <pre><code>var results = text.componentsSeparatedByCharactersInSet(NSCharacterSet(charactersInString: ","))
  text = results.joinWithSeparator(" ")
  results = text.componentsSeparatedByCharactersInSet(NSCharacterSet.whitespaceAndNewlineCharacterSet())
  </code></pre>
  
  <p>(one-line) SOLUTION:</p>
  
  <pre><code>var results = text.componentsSeparatedByCharactersInSet(NSCharacterSet(charactersInString: " ,\u{000A}\u{000B}\u{000C}\u{000D}\u{0085}"))
  </code></pre>
  
  <p>Explanation is below.</p>
