title: xcode 7 beta 5 can not download simulator
body: <p>After installing xcode7 beta5 I ran a simple project on simulator, but simulator showed an error:</p>
  <blockquote>
  <p>The com.apple.CoreSimulator.SimRuntime.iOS-9-0 simulator runtime is not available.</p>
  <p>Download the com.apple.CoreSimulator.SimRuntime.iOS-9-0 simulator runtime from the Downloads section in Xcode's Preferences.</p>
  </blockquote>
  <p>But when I go to the preference download folder it's empty in components after check and install.</p>
