The problem seems to be network-specific, the console log points to two possible errors causing the slowdown:
nw_resolver_create_dns_service_locked [C150094] DNSServiceCreateDelegateConnection failed: NoMemory(-65539)
or
nw_socket_handle_socket_event Socket SO_ERROR [61: Connection refused]
I tried two network configurations:
AppDelegate.m
jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];
/node_modules/react-native/scripts/react-native-xcode.sh
:
# Enables iOS devices to get the IP address of the machine running Metro Bundler
if [[ "$CONFIGURATION" = *Debug* && ! "$PLATFORM_NAME" == *simulator ]]; then
IP=$(ipconfig getifaddr en0)
if [ -z "$IP" ]; then
IP=$(ifconfig | grep 'inet ' | grep -v ' 127.' | cut -d\ -f2 | awk 'NR==1{print $1}')
fi
echo "$IP" > "$DEST/ip.txt"
fi
Network interfaces:
$ ifconfig | grep 'inet '
inet 127.0.0.1 netmask 0xff000000 <- Localhost
inet xxx.xxx.xxx.xxx netmask 0xfffff800 broadcast 10.10.7.255 <- Cable (en0)

Update with RN 0.60+
: Custom settings in react-native-xcode.sh
get overwritten when running pod install
.
The problem was that my Mac was connected to both WiFi and ethernet at the same time (en0
, en8
, and en9
were all in use). RCTBundleURLProvider
was taking the en0
as default one and it was causing some weird redirections.
I guess React Native does not support multiple network interfaces yet, so I ended up modifying AppDelegate.m
with the correct IP. The problem with this approach is that the IP changes:
#ifdef DEBUG
jsCodeLocation = [NSURL URLWithString:@"http://<en8-IP-address>:8081/index.bundle?platform=ios"];
#else
jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];
#endif
A better alternative would be to fix it in the packager itself inside react-native-xcode.sh
:
# Enables iOS devices to get the IP address of the machine running Metro Bundler
if [[ "$CONFIGURATION" = *Debug* && ! "$PLATFORM_NAME" == *simulator ]]; then
IP=$(ifconfig | grep 'inet ' | grep -v ' 127.' | cut -d\ -f2 | grep '169.254.')
echo "$IP" > "$DEST/ip.txt"
fi
