title: Old interface displayed after Application update
body: <p>Sometimes, i have strange behaviour while running new version of my applications (native ios application, developed under XCode 4.3).</p>
  
  <p>It seems like some old interface parts displayed, while running new version of application.</p>
  
  <p>It occurs on IOS simulator and on real device, connected to developer machine.</p>
  
  <p>Deleting Derived data doesnt help. Cleaning sources doesnt help.
  Deleting and Reinstalling application <strong>helps</strong>, but i afraid what some users can see old interface. </p>
  
  <p>How to be totally sure what users will see new interface ?</p>
  
  <p>I took a look on similiar question <a href="https://stackoverflow.com/questions/5714372/how-to-empty-caches-and-clean-all-targets-xcode-4" title="here">here</a> and <a href="https://stackoverflow.com/questions/12236450/xcode-simulators-shows-correct-xib-interface-but-on-device-its-showing-old-i" title="there">there</a> but didnot found answer - how to be sure what users will see new interface after application update. Reinstaling application is not solution.</p>
