title: Swift function alias
body: <p>How can I create an alias for a function in swift?</p>
  
  <p>For example</p>
  
  <p>I want to call </p>
  
  <pre><code>LocalizedString("key")
  </code></pre>
  
  <p>and it should call </p>
  
  <pre><code>NSLocalizedString("key", comment:"")
  </code></pre>
  
  <p>I saw <code>typealias</code> command but it looks like it works only for types.</p>
