在物理iOS设备上无法启动react-native（9.3）

Question

Only using the react-native-cli starter without changing any app code, I've done everything possible to launch on physical device.

I've followed the react-native docs, changed the IP address to my mac's, provisioned my phone, everything. Please help, as I've spent hours on this.

It seems the react-native0.29 AppDelegate file is different than 0.21. Could this be problem?

Here's the error screenshot: Error

Try commenting out:

[[RCTBundleURLProvider sharedSettings] setDefaults];
jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];

and add

jsCodeLocation = [NSURL URLWithString:@"http://ipaddressofmachine:8081/index.ios.bundle?platform=ios&dev=true"];

Also try restarting the physical device

Clearing watchman if using it watchman watch-del-all

Clear packager temp rm -rf $TMPDIR/react-packager-*

Quit everything and restart your computer
