React Native using pre-bundled file on device, even if DEV-mode


In react native 0.40.0, React native try to guess bundle location by itself. Please see if following points can help:

  • Make sure your AppDelegate.m have this line:jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];

  • Check your device and your Xcode mac is running on same wifi. Internally for IOS, react native try to guess ip by itself.

  • Try running app first through command line, so dev packager server is running and then run app through xcode in your device.


so your problem is here:

Change code in your AppDelegate.m:

jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"]; // comment this linejsCodeLocation = [NSURL URLWithString:@"http://xxx.xxx.x.xx:8081/index.ios.bundle?platform=ios&dev=true"]; //uncomment this line  

Cheers:)


As i have faced same problem and above points didn't work for me. i got it worked by doing these steps.

  • Go to xcode-> your project-> info.plist
  • In "App Transport Security settings" make "Allow Arbitrary Loads" Yes.

it should fix this issue.
