title: Ambiguous reference to member 'removeAll' in Swift 2.0
body: <p>I recently upgraded Xcode to version 7.2 and after that I am getting the error:</p>
  
  <p><code>var pEventIdsArray : Array = [""]</code></p>
  
  <p>In <code>viewDidLoad()</code>, I am using <code>self.pEventNamesAgoArray.removeAll()</code>. This is where I get an error of <code>Ambiguous reference to member removeAll</code></p>
