  <p>I'm running into the same problem as reported in this <a href="https://stackoverflow.com/questions/30872040/installing-ios-simulator-8-3-8-4">question about XCode 6</a>. I have Xcode 6 still installed, but am trying to install the simulator to Xcode 7 beta 3 where iOS 8 is no longer the base OS.</p>
  
  <p>Error msg:</p>
  
  <blockquote>
    <p>Could not download and install iOS 8.3 simulator. Authorization is required to install the package</p>
