Xcode 6.0.1 - iOS Simulator Black Screen

I have seen many questions about this, but none of them solves my problem.

The setting is as follows

OSX Mavericks 10.9.5 Xcode 6.0.1 iOS Simulator 8.0 (550.1)

I tried now with 5 different Xcode projects that work with another machine with the same settings, except that it does not work.

Every time I run the simulator, regardless of whether it works or not, or autonomously, I get the same thing.

When I run from Xcode, I get this message ->

 An error was encountered while running (Domain = com.apple.CoreSimulator.SimError, Code = 146)

What I tried:

  • Reset all contents and settings (when I click and confirm this - nothing happens at all)
  • Removed all devices from the simulators and re-created.
  • Make sure everything is up to date
  • Cleared all projects, NECESSARY TIMES
  • Restarting the machine in the meantime to do everything under the sun
  • Remote Derived Data

This has been happening for 3 days.

Suggestions please!

This is probably not the “official” answer, but my solution for this was literally bin xcode, empty trash, and then reinstall from the App Store.

This post on the Apple Developer Forums contains tons of very relevant information. It does not seem to directly affect your problem, but try the following:

  • Enable debug logging for the simulator:
  defaults write com.apple.iphonesimulator DebugLogging -bool YES
 defaults write com.apple.CoreSimulator DebugLogging -bool YES
  1. Close and restart the iOS simulator.
  2. For more information check ~/Library/Logs/CoreSimulator/*.log .
