My app is working fine on the web but stuck on the XCode Simulator upon running the initiating cmd expo start
List of files
Tried removing node_modules , package-lock etc but nothing seems to work
App has been reloaded numerous times but only works on web.
I found where the problem was, having expo-splash-screen was causing this issue. I was using this in a useEffect to load my project font but having removed this package resolved the issue.

My React native app working fine two days ago but when I installed new library and did pod install then app is not running and showing error "RnAlarmNotification.h file not found" in ios app on xcode.
I tried to run application for implementing Stripe 3ds but app is not running. now I need to solve "RnAlarmNotification.h" file not found issue to further development.
Screen shot the error what issue I am facing.
I am an intermediate react developer.
I was running my react native app peacefully without any problems untill one morning, i did not change anything in my codebase but when i tried to run the app through expo client, it started showing the error in the screenshot.
I have checked and checked this platform, and not a single solution.
I am currently using expo sdk 43 (managed workflow) please help...this is my first time posting here.
This is the error below;
Can't find variable: require
http://127.0.0.1:19000/node_modules/expo/AppEntry.bundle?platform=android&dev=true&hot=false&minify=false:5:24.globalcode#http://127.0.0.1:19000/node_modules /expo/AppEntry.bundle?platform=android&dev=true& hot=false&minify=false:720:3.
Click here for the screenshot of the error
I got it fixed.
See what i did,
I created a fresh expo project using "expo init"
Then copied all my files into the new project "except node_modules and .expo folders".
Then i ran "npm install"
Viola!!! Everything works fine now
Note: i tried removing "node_modules" before over and over again and it dint work.
The only thing that worked was starting a new project and following the above steps.
I keep my project(s) relatively up to date with the latest RN releases. This error seems to be coming up more and more lately.
Error: Unable to resolve module `./debugger-ui/debuggerWorker.d9da4ed7` from ``:
None of these files exist:
* debugger-ui/debuggerWorker.d9da4ed7(.native|.native.js|.js|.native.json|.json|.native.ts|.ts|.native.tsx|.tsx)
Really makes it hard when trying to debug issues and a debugger statement does noting and errors are not reported to the browser tab where the console output goes.
I've already tried wiping node_modules. Is this a known issue with a concrete fix available?
Got stuck with this exact issue for hours. Just found that this occurs only on device where app is already installed with debug mode enabled.
I fixed it by:
uninstalling manually app from device (cmd+H to display simulator home) then long click on app icon and click on cross to delete app => this forces disabling debug mode,
then run app again from xcode.
Enabling debug mode after that works normally.
I had to come across a similar issue after updating #react-native-community/cli-debugger-ui to 4.2.1. Tried out several methods, nothing worked. Reverting #react-native-community/cli-debugger-ui back to 3.0.0 resolved the issue for me.
I closed the app (pressing home twice and swiping up), then started it again from the simulator and it worked.
Happens to me recently using expo and android.
The solution was to clear all Expo Go data:
Long press the Expo go icon
Then select App info
At the bottom of the screen, press Clear Data
And press Clear all data
Relaunch expo go and the react native app
I have been working with React native for a few days now. Everything seemed to be working fine until I installed Nativebase. Now either I would get this error:
OR it would get stuck at around 97% while Building JavaScript bundle after a couple of Project restarts and clearing cache. This happens regardless of whether I'm running on my phone or the emulator. I'm using the Expo XDE but its the same with the cmd.
I have a problem when running react-native run-ios on my project.
The IOS emulator launch well.
Then the application start (react-native white splash screen) and immediately after that, it return me to the Iphone home screen.
If I Cmd-Shift-H (with pressing H two times) I saw the app in the background (still with the react-native white splash screen).
When I click on it, it return me to the home screen again.
If I launch the Xcode project and run the app, it work fine and I can navigate in my application.
I've had some troubles with my app before, the IOS version was 'abandoned' and I've installed a lot of modules and changed the name of the project in the mean time, before trying to make it work on IOS.
Then I've decided to create a new project with react-native init myNewProject (because I couldn't figured out how to fix the IOS, something with a workspace not configured) and copy paste my old src and index.ios/android.js inside.
So now Android is still working and IOS is only working if I launch the app from Xcode.
I've tried to reset the emulator but it don't change anything.
I don't have any logs about app crash or something.
The Android app version is working fine.
Any idea ?
Logs
I've put the device logs after running react-native run-ios on a gist

Additional Information
React Native version: 0.35
Platform: IOS
Operating System: macOS El capitan
Xcode: Version 8.0
I ran into this problem, and solve it:
In my case i install third-party native component in my project and link it using command react-native link <component-name>. Than i have a problem about you wrote:
Running project by Xcode - works fine. Bundling start, after loading dependency graph.
But runnig project by react-native run-ios app hide immediately and bundling not started after loading dependency graph. And not any errors happened.
I tried reinstall all, clean npm cache, react-native upgrade, delete build folder, delete derived data... nothing helped.
I found one way that helped me:
I remove that problem library not manyally from Xcode, but from terminal using command react-native unlink <component-name>. Its way to resolve this problem for me, maybe for you too.
Sorry for my english.
