Description

I have a project that contains multiple iOS apps. The React Native CLI is selecting the incorrect iOS project, so I'm trying to specify a project.ios.sourceDir in my react-native.config.js as per the CLI docs, but this is leading to the npx react-native config command failing with the following error...

someUser19m:CustomIOSLocation some.user$ npx react-native config
error Failed to load configuration of your project.

Reproducible Demo

1. Create a new project

npx react-native init CustomIOSLocation

2. Rename the ios/ folder to custom-ios-location/
3. Create a react-native.config.js file at the root of the project
4. Paste the following into the file:

module.exports = {
  project: {
    ios: {
      sourceDir: './custom-ios-location',
    },
  },
};

5. Run the following command:

npx react-native config

Expected: RN CLI prints the project native linking configuration using the provided location for the iOS project.

Actual: RN CLI fails to print configuration and instead gives a "Config Validation Error: "project.ios.sourceDir" is not allowed" error

Did a bit of digging into the CLI source code... It looks like for a custom Android project location you'd usesourceDir, but for iOS you'd use project...

module.exports = {
  project: {
    android: {
      sourceDir: './custom-android-location',
    },
    ios: {
      project: './custom-ios-location/ios/YourIOSProject.xcodeproj',
    },
  },
};

Not sure whether this inconsistency is intentional (if so we should update the documentation)? Or is this a bug?

I think this issue is now fixed, but on my end I had to use the following code because relative ./custom-ios-location doesn't work

const path = require('path');

const projectConfig_ios = {
    sourceDir: path.resolve(__dirname, './custom-ios-location')
}

module.exports = {
    project: {
        ios: projectConfig_ios,
    },
};

I'm not sure if it's an issue with glob or the OS, but I tried creating a test.js with the glob code using the relative path, ran it in the root project, and it worked

Hopefully this should work for you:
