react-native: Can't build release version of app - __fbBatchedBridge is undefined
I’ve got an app ready to go live, but I’m unable to build a release version.
Steps I took:
- In Xcode, edited the scheme and set Build Configuration to Release and unchecked “Debug executable.”
- In Terminal, ran
react-native bundle --platform ios --dev false --entry-file index.ios.js --bundle-output ios/main.jsbundle --resetCache - Set Xcode build target to Simulator (5s, iOS 9.3) and hit run.
I get the following error:
2016-02-04 18:59:17.582 [error][tid:com.facebook.React.JavaScript] Unable to execute JS call: __fbBatchedBridge is undefined

I’m not sure if my case applies here but I had the “__fbBatchedBridge is undefined” issue when I tried to build a production app and the reason was that my “schema” in XCode was set to “Debug”. --> Changing to “Release” fixed the issue.
+1 on 0.22.2

Nice to see some other voices join in here. I still feel that, out of the box, it should not fail when using bundle mode in the simulator.
I got this same error on 0.20.0, and it was because my Appdelegate.m file had the line for running on the simulator uncommented, and I was trying to run on a physical device. I switched back to the other line and it ran fine.
still seeing this with RN 0.33.0 and React 15.3.1
Similar to @kwelch, I needed to do a manual upgrade from 0.13 -> 0.14. Was able to fix issue on 0.21.0 by following the Manual Upgrades section of https://facebook.github.io/react-native/docs/upgrading.html#from-0-13-to-0-14
I also think this is wrong. Especially since Facebook (!!) requires a working Simulator version for App Review. It makes much more sense to use Debug / Release configs as a determinator whether a bundled version should be created / used, or whether the local packager should be used.
You can uncomment these line in react-native-xcode.sh: https://github.com/facebook/react-native/blob/master/packager/react-native-xcode.sh#L15-L18 and make sure your rootview/bridge config points to the right JS file.
Still seeing this on 0.46.1
Still seeing this on 0.45.0

I’m getting it on 0.47.1
My app starting to show this error in the middle of development. Delete the app from the simulator and run
react-native run-ios.25 to .29 - getting this. Can’t seem to get it to work with any of the above suggestions. Only breaks on a physical device, not emulator.
also fall into this and found out the script is
"Skipping bundling for Simulator platform"… I think it’s wrong, you shouldn’t prevent us from testing the “bundle” mode on the simulator.
