body: <p>I used to use tabs for indentation and spaces for alignment. 
  Like so (arrows show tabs and dots show spaces).</p>

  <p>In QtCreator you can set such coding style in standard preferences.
  I can't find the way to achieve the same goal in Xcode. Could you please tell me if it is possible?
  May be there is a plugin for that?</p>
  
  <p><strong>UPDATE:</strong>
  Here is how it can be achieved in QtCreator:

  <p>P.S. Please, don't try to persuade me that using spaces only/tabs only is better, otherwise this question will turn into another holywar :)</p>
