title: Swift 3 replacingOccurrences of multiple strings
body: <p>I have JavaScript code that looks like the following:</p>
  
  <p><code>foo.replace(/(\r\n|\n|\r)/gm, "");</code></p>
  
  <p>Basically this strips any return carriages and new lines from my string. I'd like to do something similar in Swift 3. </p>
  
  <p>I see <code>func replacingOccurrences(of target: String, with replacement: String, options: CompareOptions = default, range searchRange: Range&lt;Index&gt;? = default) -&gt; String</code> is available. The problem is, this only takes one string in the <code>of</code> parameter. </p>
  
  <p>Does this mean I need to call the method multiple times for each of my instances above, once for <code>\r\n</code>, once for <code>\n\</code> and once for <code>\r</code>? Is there anyway to potentially accomplish something closer to what the regex is doing instead of calling <code>replacingOccurrences</code> three times?</p>
