title: Xcode 6 (non-app store) Hangs When Creating New Simulator
body: <p>After upgrading to the latest release version of Xcode (7.0), I was made aware that further work by me was needed on an older project that is still being developed in Xcode 6.x/Swift 1.2. I downloaded Xcode 6.4 as a dmg from Apple's developer site (the Mac AppStore only installs Xcode 7.0 now), and installed it side-by-side by choosing "keep both" and changing the name from "Xcode 2" to "Xcode 6".</p>
  
  <p>The first time I opened my project and tried to run it on the simulator, I got an alert saying that "Could not connect to simulator" or something similar (didn't write down the exact wording). I had to force-quit both Xcode and the simulator, then relaunched.</p>
  
  <p>This time, I can not select any simulator from the pull down menu beside the schemes. I checked "Window / Devices" and it turns out <strong>there is no simulator installed</strong>. </p>
  
  <p>If I click on "Add" (+), specify the properties of the simulator and then click "Create", then <strong>Xcode hangs and I have to force-quit it</strong> again.</p>
  
  <p>Anyone experiencing something similar?</p>
