title: AppCode + swift - no code completion and no quick documentation
body: <p>Do anyone know how to enable code completion and quick documentation in <strong>AppCode</strong>(3.1.1) for <strong>swift</strong>?
  I have updated Xcode I've downloaded documentation in Xcode preferences. 
  I set correct path to Xcode in my AppCode but still I got no support in AppCode regarding to completion and quick documentation.
  This support is in XCode but I am java dev so for me better thing is to use Jetbrains tool instead of using Apple one.</p>
  
  <p>Project that I've opened in AppCode was created in XCode.
  I've downloaded this documentation in XCode.

  <p>I've searched a lot in the net but there are only slogans about features of AppCode</p>
  
  <p><code>can do that this, is doing this and that</code> </p>
  
  <p>Only one thing related to path to XCode I found in this property

  <p>but none of those I can see... I believe that I haven't enabled it yet.</p>
  
  <p>For me AppCode is more user friently tool because like I said I am used to Intellij for Java development and I am trying to use this tool because it is quicker for me to work with sth that I've used to than sth that is completly new for me(conceptually - XCode).</p>
  
  <p>Do you have any advices about that?</p>
