Description

React Native version mismatch.

JavaScript version: 0.56.0 Native version: 0.55.3

Make sure that you have rebuilt the native code. If the problem persists try clearing the Watchman and packager caches with watchman watch-del-all && react-native start --reset-cache. regeneratorRuntime is not defined

It only happens in iOS on Debug mode. It works fine on Release mode or Android.

Reset cache wasn’t worked for me. For me, deleting whole build file and restart worked.

rm -rf ios/build
react-native run-ios

Have you fully uninstalled the app on the simulator/device? It’s possible that the build may be failing and instead launching a previous version of the app.

i have the same issue. This only happens when I run react-native run-ios, but if i run project direct with XCode, it works fine. And it only happens in iOS. Does anyone have other ideas why it that so?

alberttra on Aug 14, 2018

Yes I’ve done that. Here you can reproduce the issue It happens on iOS only (debug build)

@maggialejandro How would I do that correctly? Remove the React.xcodeproj from Libraries in Xcode and add it again?

That error is saying that your app was built & installed with RN 0.55.3 and you’re trying to run it with a javascript bundle that has RN 0.56. You need to rebuild & reinstall the app using react-native run-ios / run-android
