Hello I'm facing a problem with Expo React-Native. Whenever I try to launch the iOS Simulator. I get this error:

Screenshot of Expo Results

My NPM Version is 6.7.0 react-native-cli: 2.0.1 react-native: 0.57.1 Expo Version 2.11.9

Also I made sure my Command Line tools on Xcode is setup perfectly Xcode CommandLineTools

Finally, I also tried to run the command sudo xcode-select -s /Applications/Xcode.app

Nothing works..

I had the same problem, fixed it by manually starting the simulator app before starting expo.

The app is located in /Applications/Xcode.app/Contents/Developper/Applications/Simulator.app
