iOS Simulator crashing on open

Hey everyone,

My iPhone Simulator is crashing and I have no idea why. I do not have any other version of xcode installed. Help would be much appreciated, thank you!

  • Things I've tried:
  • Restarting my Mac
  • Deleting DerivedData
  • Removing and adding simulators again
  • Deleting simulator devices folder
  • Deleting and reinstalling XCode

I can provide additional logs if needed.

Did you try to create a brand new project (doing nothing) and see if it crashes. If no, problem is in your code. If yes, may be you need to reinstall Xcode. But I understand you did this reinstall already.
