title: xcode change target from 'iOS device' to the simulator
body: <p>I had a project in xcode and didn't touch it for a month (and forgot how it works).</p>
  
  <p>Now I want to change the target from 'iOS device' to the simulator.</p>
  
  <p>I can not for the life of me figure out how I should do this in xcode 4.5.2</p>
  
  <p>-- EDIT FOR CLARITY --</p>
