title: XCode Ambiguous reference to member
body: <p>Recently I upgraded my XCode to version 8.  After doing so I was unable to compile my project because I got a Swift Compiler Error.  Here is an example of what the errors are:<br>
  Ambiguous reference to member 'dataTask(with:completionHandler:)'<br>
  Ambiguous use of 'appendingPathComponent'<br>
  Ambiguous reference to member 'continue'<br>
  etc,</p>
  
  <p>What could be causing this bugs after updating and how can I resolve them?</p>
