Port already in use red-screen #
Something is probably already running on port 8081. You can either kill it or try to change which port the packager is listening to.
Kill process on port 8081 #
$ sudo lsof -n -i4TCP:8081 | grep LISTEN
then
$ kill -9 <cma process id>
Change the port in Xcode #
Edit AppDelegate.m to use a different port.
// OPTION 1
// Load from development server. Start the server from the repository root:
//
// $ npm start
//
// To run on device, change `localhost` to the IP address of your computer, and make sure your computer and
// iOS device are on the same Wi-Fi network.
