title: Xcode autocomplete to show suggestion when "Contains" rather than"Start with"
body: <p>Being a .Net developer I've vastly worked with Visual Studio and Jetbrains Resharper. 
  When using Resharper and VS, autocomplete suggestions appear when suggestions <strong>contains</strong> word being typed rather that <strong>start with</strong>. I've seen similar behavior in Jetbrains AppCode.</p>

  <p>but Xcode, with default settings, just shows suggestion when the suggestions <strong>start with</strong> the word being typed!</p>

  <p>Just wondering if we can somehow modify this behavior to suggest words <strong>containing</strong> rather than <strong>starts with</strong>.</p>
  
  <p>I've looked at <code>Xcode &gt;&gt; Preferences &gt;&gt; Text Editing</code>, but couldn't find anything.
  P.S. Why I'm not using AppCode if I need this feature? My 30 days trial evaluation is up! </p>
