Create-react-native-app: Xcode won't compile a fresh-ejected app

[pbassut]

Please make our job easier by filling this template out to completion. If you're requesting a feature instead of reporting a bug, please feel free to skip the Environment and Reproducible Demo sections.

Description

Looks like at some point in the eject process when generating the ios project #import <React/RCTDevSettings.h> is being referenced and can't be found.

Expected Behavior

I was expecting it to run as a normal react-native app.

Observed Behavior

I was expecting it to compile normally as a react-native app would. Both in Xcode and running react-native run-ios but then this happened:

In file included from /Users/patrickbassut/Programming/beebo/.expo-source/ios/ios/Exponent/Versioned/Modules/Internal/EXDevSettings.m:3:
/Users/patrickbassut/Programming/beebo/.expo-source/ios/ios/Exponent/Versioned/Modules/Internal/EXDevSettings.h:3:9: fatal error: 'React/RCTDevSettings.h' file not found
#import <React/RCTDevSettings.h>
        ^

Reproducible Demo

create-react-native-app myApp
yarn run eject // Chose to use a Expo account and still have expo SDK
react-native run-ios // breaks

Hi! Thanks for the report! We discovered this earlier today, and I'm in the process of releasing a fix for it.

[pbassut]

I looked for it and it wasn't reported. Thus I created the issue.
Lost a few good hours thinking the issue was on my end.
So glad you guys are already working on it.

Thanks so much!

[anp]

If you change your package.json so that the react-native dependency matches this:

"react-native": "https://github.com/expo/react-native/archive/sdk-15.0.0.tar.gz"

and you follow this guide you should be able to get things building. I'll close this when the fix is released.

[anp]

And to be clear -- the issue was reported outside of GitHub, no duplicate issue here. Thanks for checking first though! Makes life a lot easier :D

[pbassut]

@dikaiosune Thanks for the fast response! You're a wizard!

[pyankoff]

Hey guys, I'm still getting this issue with the latest version :(

[anp]

@pyankoff can you paste the contents of your package.json?

[pyankoff]

Hi @dikaiosune Thank you for quick reply! Sure:

{
  "name": "test",
  "version": "0.1.0",
  "private": true,
  "devDependencies": {
    "jest-expo": "^0.3.0",
    "react-test-renderer": "~15.4.1"
  },
  "main": "index.js",
  "scripts": {
    "test": "node node_modules/jest/bin/jest.js --watch"
  },
  "jest": {
    "preset": "jest-expo"
  },
  "dependencies": {
    "expo": "^15.1.0",
    "react": "~15.4.0",
    "react-native": "https://github.com/expo/react-native/archive/sdk-15.0.0.tar.gz"
  }
}

Used the same process:
create-react-native-app myApp
yarn run eject // Chose to use a Expo account and still have expo SDK
react-native run-ios // breaks

[anp]

@pyankoff have you read the guide? IIRC it's linked from the CRNA docs and from the eject completion message.

[pyankoff]

I did, I even used exp detach and managed to run detached ios app before. Did I miss anything?

[anp]

Oh I'm sorry, I forgot that doc was split up, I was referring to https://docs.expo.io/versions/v15.0.0/guides/expokit.html. The thing I noticed in your comment above is that you used react-native run-ios in an ExpoKit project, which I don't think works.

[pyankoff]

No worries, I figured you meant both docs. Yeah, I picked up running with react-native run-ios from this thread, but I'm getting the same error when trying to run the project from xcode.

[anp]

What's the error when running from Xcode?

[pyankoff]

/test/.expo-source/ios/ios/Exponent/Versioned/Modules/Internal/EXDevSettings.h:3:9: 'React/RCTDevSettings.h' file not found

/test/.expo-source/ios/ios/Exponent/Versioned/Modules/Internal/EXDevSettingsDataSource.h:4:9: 'React/RCTDevSettings.h' file not found

[anp]

Can you try re-installing node_modules (delete n_m, then reinstall) followed by a pod install?

[pyankoff]

Now it builds! Thank you!

[anp]

Hooray!

Command failed: /usr/libexec/PlistBuddy -c Print:CFBundleIdentifier build/Build/Products/Debug-iphonesimulator/SampleApp.app/Info.plist
Print: Entry, ":CFBundleIdentifier", Does Not Exist

[n1ru4l]

@rachurirkk did you resolve that problem, I did an eject and I also get that error. Tried to reinstall node_modules and also pods

[comur]

Hi,
I have the same issue as @rachurirkk even after rm n_m and reinstall + pod install.
pod install returns following error (don't know if it's normal or not):
[!] No `Podfile' found in the project directory.

I cannot run from XCode neither

Thanks

[n1ru4l]

@comur is here a Podfile in that directory? It should be located insode the ios folder.

After reading many message boards, I had to only upgrade from Xcode 9.2 to 9.3 and it compiled.
