title: SFSpeechRecognizer init not accepting Locale
body: <p>I'm trying to initialise an instance of <code>SFSpeechRecognizer</code> but I get the following error <code>Cannot convert value of type 'Locale' to expected argument type 'Locale'</code> which doesn't make any sense to me. Bellow is my initialisation code.</p>
  
  <pre><code>let speech = SFSpeechRecognizer(locale: Locale().initWithLanguageCode(languageCode: "en-US") as! Locale)
  </code></pre>
