title: 'init()' is deprecated: init() will be removed in Swift 3. Use `nil`
body: <p>I was using this code.</p>
  
  <pre><code>var audioUnit:AudioUnit = AudioUnit()
  </code></pre>
  
  <p>But in Xcode 7.3 (Swift 2.2) I am getting this warning. Any idea why? And how can I get rid of that?</p>
  
  <p>N.B. Is I use <code>nil</code> then my program crashes.</p>
