I'm building a react native project and I got this error on running.
Can you please help me to resolve this issue?
This happened to me because I ran react-native run-ios immediately after installing code-push. It turns out that I needed to run pod install in my ios directory, then clean and rebuild to make this work.
I resolved it following steps below.
Create account on code-push(microsoft.github.io/code-push) and register into collaborator on existing app.
Run code-push app ls on terminal and see if registered successfully.
Run code-push deployment ls "appname" -k on terminal to get deployment keys.
Run react-native link and enter the keys on prompt.
I met the same issue as described in this problem. I tried both answers, but neither worked. After being stuck by a codePush undefined problem, I figured out that it's my fault. I missed a important step in CodePush readme tutorial: iOS setup:
After pod install and updating info.list, undefined codePush disappeared and everything worked well.

I'm trying to build a react-native sketch project and I believe I've installed all the required libraries for it to work on my machine, but for some reason I keep on getting this error, which I'm not sure how to resolve.
Also, I wasn't sure what it meant by the linking of the react native to react native sketch, when installing the react-native sketch.
react-native link react-native-sketch
Maybe sharing your code will help debug the issue. But if the code is right then see below for installation.
So when installing this package, it is not enough to just install it. You must link to React Native. So do;
npm i -S react-native-sketch
That will install it. Now to make React Native 'aware' of this newly installed package, link it as follows;
react-native link react-native-sketch
This is just putting it in simple terms for understanding.
You should get a success message for both of the above - if an error occurs while running any of the above command lines, then it did not succeed and you'll get the error above.
If developing on IOS, don't forget to pod install and re run the project after installing the package!
CD to IOS directory - type 'pod install' and ENTER. Re Run the project.
I have a simple React Native app that I've been testing on Android and now want to test on iOS. It's using React Navigation.
I ran npm run ios but I'm getting the following error:
info In file included from
/Users/rbbit/reactnative/testproj1/ios/testproj1/main.m:10:
/Users/rbbit/reactnative/testproj1/ios/testproj1/AppDelegate.h:9:9: fatal error: 'UMReactNativeAdapter/UMModuleRegistryAdapter.h' file not found
#import <UMReactNativeAdapter/UMModuleRegistryAdapter.h>
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
info 1 error generated.
I opened XCode but I'm basically getting the same message, nothing else that would help me debug this.
I do see that there is a package called react-native-adapter (https://github.com/expo/expo/tree/master/packages/%40unimodules/react-native-adapter), however I'm hesitant to just install this since I followed the instructions on how to include react-navigation and didn't mention that, assuming this is related.
Also, that page says If you are using react-native-unimodules, this package will already be installed and configured!, and react-native-unimodules already is in my dependencies.
Any pointers on how to solve this? Thank you!
For latest RN versions (RN 0.60+) errors like this should be fixed with the auto-linking and just running a pod install.
For older versions you should try:
react-native link in the root folder of your project
Then in Xcode Product->Clean Build folder, restart JS server and attempt to rebuild.
If still not working double check the configs from here:
https://github.com/unimodules/react-native-unimodules
and the App.delegate from here:

Pod install reminder was first suggested by Sandy in the below comment
pod install didn't work for me until I added these lines to my pod file:
require_relative '../node_modules/react-native-unimodules/cocoapods.rb'
And
use_unimodules!(modules_paths: ['../node_modules'])
Then do a pod install.
Example: https://gist.github.com/sjchmiela/6c079f2173938a9a61a7c6f053c45000
I had this exact same error with everything configured correctly, everything in the other answers done and all the unimodules installation steps already done, on a project that had worked for months, building it on a new computer. It turned out the reason was because I was simply using the wrong file in xCode.
I had opened the .xcodeproj file when I should have opened and run the build from the .xcworkspace file.
Everything seemed to work as normal apart from this error, which made it look like a configuration problem rather than a simple "you opened the wrong file" problem. Hopefully if someone else makes the same mistake, this will save them a few hours of fruitless tinkering.
I am getting this while running app on simulator using xCode, version 9.2
I've tried other solution mentioned on Stack overflow & Github S1S2 S3 S4 but most of the solution are mentioned for android.
P.S. This project also includes purescript code explained here Integrate Pure Script in your React Native project
That's how I resolved it.
Terminate your metro bundler > react-native link > react-native run-ios
It was not bundling because of some errors which was not showing in the simulator but just this error was thrown.
create index.js, index.android.js and index.ios.js whith the same content. I do have all of them and it solved my issue
I have also faced the same issue when I changed the name of images saved in my local directory. In my case, I have just restarted metro bundler, deleted the app, and restarted the app. Issue was fixed for me.
Try this:
npx react-native-asset
then:
react-native run-ios
This issue is caused basically when some packages or images are not bundled properly, it might be caused because of improper assets path or internet issue when installing packages or reload issue. The expo bundles into a standalone library so it can be available immediately.
This error does not provide any stack to debug since it does not properly have the bundled data even for error stack.
I have just face few bundled scenarios
Scenario 1 => While the expo is running and we install a new library on fly, few times during this importing the library might not get bundled properly, so it's better to stop the expo and re-run, or try reloading the error in app. This will some time resolve the issue, or if there is some error it will show up the error stack
Scenario 2 => You have a customised asset director or have changed the asset path in app.json file improperly.
Please let me know in comments if there are any other scenarios
I had a metro bundler terminal window opened and whenever I was running npm run ios , it wasn't starting a new metro server, the problem was that. I closed the metro bundler terminal window and ran npm run ios and it opened a started a new metro server and the error was gone
I had a same issue, then I did:
rm -rf node_modules,
npm install
and restarted the metro (npm start). It worked.
In Settings, go to Privacy > Local Network to see a list of every app that requested access. I solved by allowing my app to access to the local network. (Trying to run on physical iPhone device from my mac m1 on the same wifi).

Make sure that when you restart the expo project you do so with expo start -c
-c throws out the cache, otherwise the problem persisted for me.
I had a old React-Native project which I wanted to give it a try again and when trying to run the project on iOS (Android works perfect) I get the error that Debug-iphonesimulator/GeneratedInfoPlistDotEnv.h file not found.
If I run the project from the command react-native run-ios, than the build will succeed.
What can cause this issue and how can it be fixed?
I have tried to fix it with the comments from this issue but no success.
React-Native verision: 0.47
Full error:
<built-in>:1:10: fatal error:
'/Users/myUser/Library/Developer/Xcode/DerivedData/Project-gcaxrvbcwgkfhkadevoqxcprxszw/Build/Products/Debug-iphonesimulator/GeneratedInfoPlistDotEnv.h' file not found
I fixed by copying file GeneratedInfoPlistDotEnv.h (in /ios/build/Build/Products/) to the path mentioned in the error message.
The path mentioned in error message for simulator is not same as real phone, you need to copy for a second time.
The development for React Native just like droped in a deep black hole, what you need to do is just climb and climb and climb...
Changing the Info.plist preprocessor prefix file to works for me ${CONFIGURATION_BUILD_DIR}/../GeneratedInfoPlistDotEnv.h

If you're coming from React version 0.60 and above, you should be referencing the package from GitHub instead of NPM. The author hasn't released auto-linking support on NPM yet, even though it's already merged!?
Try these steps after you unlink and uninstall the existing version of react-native-config. Remember to revert to default Info.plist preprocessor settings in XCode build settings.
yarn add https://github.com/luggit/react-native-config.git
cd ios && pod install
You don't have to add any other post-install scripts, just run the app like usual and it should work fine. Make sure you undo any other fixes before doing this.
I recently added bugsnag-react-native and followed the directions for linking. When I run using the packager without Xcode, I get the following error screen.
When I search on Google for answers, the only relevant issue posted is Runtime Error: No Native client found which suggests that its a linking problem and to follow the directions, but from my perspective everything looks fine and I followed the direction.
What reason would a native module only be available when run from Xcode?
I had a similar issue and below solved it:
If you can successfully run from Xcode, then delete your ios/build folder (rm -rf ios/build) and re-run react-native run-ios.
