react-native: [iOS] [0.68.0-rc.4] 'react/config/ReactNativeConfig.h' file not found

I removed my ios/build/ and ios/Pods/, rebuilt everything, and it now compiles with RN 0.68.0. @AlexanderEggers have you tried this?

@baveku I’ll try to explain how I solved my issue with this error:

• 3.0.2 version in react-native-reanimated didn’t help

Reading the react-native-config documentation I just realised Apple changed the way we have to import libraries in AppDelegate.m

So what I did was:

Replace #import “ReactNativeConfig.h” for #import “RNCConfig.h” Don’t forget to update the whole file by changing ReactNativeConfig for RNCConfig

Happy coding 😃

I am seeing a similar issue:

❌  /Users/renchap/dev/project/packages/mobile/ios/Pods/Headers/Private/React-Codegen/react/renderer/components/rncore/EventEmitters.h:12:10: 'react/renderer/components/view/ViewEventEmitter.h' file not found

#include <react/renderer/components/view/ViewEventEmitter.h>
         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Closing as this has been reported as fixed + this issue was related to a RC version of RN. We now released 0.68.2 stable.

I have this issue in 0.68.2

I’m also getting the same issue:

seems like it’s related to react-native-reanimated “react-native-reanimated”: “^2.8.0”, “react-native”: “^0.68.1”,

yes, Reanimated v2 not support new Architecture, We need to wait for Reanimated release v3, Maybe next month, we can use it. Announcing Reanimated 3

Cannot build ios app with v0.68 on with or without New Architecture Enabled.

I have had patience for many days trying diff methods but still was not able to fix any and had to come up here and report.

Yes i have the same problem, so I make new project on New Template without follow migrate doc in reactnative.dev and replace file in AppDelegate.mm and reinstall all package, It’s work, you can replace new Appdelegate.mm to fix it 😉

Thanks Your. suggestion works for me.

The content of project.pbxproj was the culprit, i just initialise a new react-native project and copied project.pbxproj into the existing project and the build works.

When does Reanimated 3 release? I saw Reanimated 3 rc0 a long time

Reanimated 3.0.0-rc.0 supports all features of Reanimated 2 except for Layout Animations.

See this comment for more details:

• https://github.com/software-mansion/react-native-reanimated/issues/3439#issuecomment-1205382650

TL;DR We will release 3.0.0 (stable) once we add Layout Animations for Fabric.

Can anyone post diffs of their project files?

@baveku Yep I am using that - might indeed be related to that. Regarding reanimated generally, the PR https://github.com/facebook/react-native/commit/58a2eb7f37c2dc27ad3575618778ad5b23599b27 would unblock the new architecture for reanimated which is planned for 0.68.1. But I think reanimated generally needs to add support to the new architecture first anyway. It is strange that fatal error: 'react/config/ReactNativeConfig.h' file not found would be thrown in this case - seems strange to me.

I was having a similar issue after enabling and disabling :fabric_enabled but this fixed it for me

@tomekzaw yes I am - I’m running my pod install commands like RCT_NEW_ARCH_ENABLED=1 bundle exec pod install as per the documentation

Reanimated 2 does not support Fabric (the new architecture). You need to use Reanimated 3.0.0-rc.10 (or newer).

Hey all! In order to use Reanimated with Fabric enabled, you must first update to 0.69+.

Reanimated 3.0.0-rc.0 with Fabric enabled does not support React Native 0.68.x.

same issue, I can’t build my project when upgrade to 0.68

 fatal error: 'react/config/ReactNativeConfig.h' file not found

I clean all cache, build, node_modules, Pods, and reinstall it. But still issue, hope we can fix it soon.

I see 3.0.2 version already available

Changing all AppDelegate.m into AppDelegate.mm inside project.pbxproj (a file with temptation not to look into) worked for me.

I was about to give up all hope, until I did this. Thanks you sir!

Same error with me too: I tried other solutions too, but there is not third-party folder exist. here is the error I guess:

ios/Pods/glog/src/base/mutex.h:105:10: fatal error: 'config.h' file not found
#include "config.h"           // to figure out pthreads support

I have this issue and I have resolve it, with just this command, npx react-native-clean-project I have no idea what this pkg cleanup but now my project is able to run on iOS & android both with the latest version of react native@0.68.2.

I was able to build the same way. Created new project. Opened in xcode beside my project and compared settings. Now it builds.

@AlexanderEggers I found something in Reanimated, I can’t build if we have Reanimated. Do you use Reanimated in your app?
