title: iPhone Simulator Can't Be Lauched?
body: <p>When I press Run on Xcode with other tasks already running, the following message appears:</p>
  
  <blockquote>
    <p>Simulator in Use. 
    The Simulator can't be launched because it is already in use.</p>
  </blockquote>
  
  <p>I checked with some friends and when they press run, Xcode automatically stop the tasks running and run the app you want. How can I configure this here?</p>
  
  <p>Thanks in advance,</p>
