Still getting "Unable to boot the Simulator" in beta 2

I've tried

  • deleting and reinstalling the beta
  • deleting and re-adding the iOS support
  • deleting and re-adding all the simulators
  • clearing DerivedData and CoreSimulator/Caches
  • rebooting
  • waiting a little while and rebuilding

Nothing works. Anyone else had any success?
