How do you pass the NO_FLIPPER to xcode? And will it be propagated correctly (how)? I'm asking because I still get the FlipperKit/FlipperClient.h not found error after adding these lines in react-native.config.js.

NO_FLIPPER=1 usually used on CI, locally it's ok to have installed Flipper

It really depends, for example we use react native Firebase which prevents using flipper, even locally. I think its worth describing how to edit .xscheme files to set (or not) the env variable to 1.

In our case we simply disabled flipper without using any configuration because we have no solution yet to make it work in any case. So we simply have:

// react-native.config.js
module.exports = {
    dependencies: {
        { 'react-native-flipper': { platforms: { ios: null } } }
    },
};
Enter fullscreen mode Exit fullscreen mode

And

# ios/Podfile
target 'AppName' do
  use_react_native!(
    :flipper_configuration => flipper_config,
  )
end
Enter fullscreen mode Exit fullscreen mode

Also I think many people don't use CI to build iOS apps because its hard (expensive) to get hands on a machine that can run xcodebuild.

Maybe, I never tried myself because I ended up removing the option to enable flipper, but I guess it should work.
