title: How to install iOS 12 simulator in the Xcode 10 beta?
body: <p>I have a fresh install of Xcode 10.0 beta 6 (10L232m) on macOS Mojave 10.14 beta (18A353d).</p>
  
  <p>When I go into Xcode -> Preferences -> Components I only see iOS 8.x through 11.x, the like for tvOS, and watchOS 2.x - 4.x.</p>
  
  <p>Everything I have read makes me think I should see iOS 12.x runtime simulators listed there as an option to download and install.</p>
  
  <p>Should they be there? If not, how can the runtimes be installed? I didn't see any info on this in my searching so far.</p>
  
  <p>Thanks!</p>
