title: xcode 6.2 cannot install old simulator by coping
body: <p>everyone.</p>
  
  <p>I found that I cannot install old simulator into Xcode 6.2 by coping now. I tried to download the 7.1 simulator in Xcode, but always get a no response message. Is there another way to install iOS 7.1 simulator for Xcode 6.2?</p>
  
  <p>Thanks.</p>
