Connection errors
I am trying to start a new project in React Native, but I am getting errors when I try to start the iOS Simulator. I haven't edited index.ios.js. I am using iOS Simulator to run a project, and the error in the emulator is "Failed to connect to development server ..."

You can try simply
nvm alias default iojs-v2
If that doesn't work, try all the steps in the installation guide again . Then in the project folder
rm -rf node_modules/
npm i
In Xcode remove RCTWebSocketDebugger
from your libraries:
YourProject > Libraries > RCTWebSocketDebugger
Then in Xcode Product -> Clean
and try to create again
