Failed to load bundle - Could not connect to development server

I've been looking for a solution to this issue for a day now but couldn't fix it.

I have not used react native for a month when everything was working fine.

Now, if I try to run an existing project that used to work (react native 0.59.5) or a brand new project (react native 0.59.9) with the iOS simulator on my mac, I get the error:

Failed to load bundle - Could not connect to development server

Any idea how I can fix this?

Ok found the issue. Was thinking it might be watchman related issue and wanted to use the command brew reinstall watchmanto reinstall it. By running this command, I found an error

Error: Xcode alone is not sufficient on Mojave. Install the Command Line Tools: xcode-select --install

Looks like the command line tools for xCode was not available anymore. I launched the command xcode-select --install and then reinstalled watchman just in case. It is now working!

Couldn't connect to development server error

This error is received when the metro bundler isn't running in port 8081. To start the bundler, from project folder run:

npm start

Now, try reloading your app (ctrl + R for iOS / r+r for Android).

Also, check your terminal in case the project failed initial build due to some error.
