Host IP in metro.config.js about metro

[aleksnied]

Actually, I've just noticed that

react-native-xcode.sh attempts to grab the USB IP Address so that physical device can connect to metro over USB. However your script only checks a few network interface numbers, up to en8, then falls back to computer LAN IP:

Enables iOS devices to get the IP address of the machine running Metro
if [[ ! "$SKIP_BUNDLING_METRO_IP" && "$CONFIGURATION" = *Debug* && ! "$PLATFORM_NAME" == *simulator ]]; then
  for num in 0 1 2 3 4 5 6 7 8; do
    IP=$(ipconfig getifaddr en${num})
    if [ ! -z "$IP" ]; then
      break
    fi
  done
  if [ -z "$IP" ]; then
    IP=$(ifconfig | grep 'inet ' | grep -v ' 127.' | grep -v ' 169.254.' |cut -d\   -f2  | awk 'NR==1{print $1}')
  fi

  echo "$IP" > "$DEST/ip.txt"

When I connect my iPhone via USB to my macbook, it's under en12, could you add more numbers to that for loop? :D

I will close this issue here and raise it against react-native itself
