Xcode shell script errors after update to Babel 7 / RN 0.57

See original GitHub issue

Current Behavior

I’m upgrading from React Native 0.56 to React Native 0.57. I have to update babel 7 to make this work. So I followed these steps from the React Native changelog. And some of the tips in #411. But I get a lot of errors from the haul shell script when I build in xCode afterwards.

Xcode (and +/- 1200 more like this)

I’m using version 0.45.1 of metro-react-native-babel-preset in my .babelrc as suggested by the React Native upgrade guide. But the same issue appears when using babel-preset-react-native (both V4 and V5).

Expected Behavior

There is no exit code so the build completes “successful” and everything in the app seems to work. But preferably without all the errors in xcode. I still have issue #487 when I make a release build which should be fixed with this haul version.

Haul Configuration (webpack.haul.js)

let srcAppPath = path.join(__dirname, 'src');
let nodeModulesPath = path.join(__dirname, 'node_modules');

module.exports = ({platform}, defaults) => {
    const config = {
        entry: `./index.js`,
        resolve: {
            ...defaults.resolve,
            plugins: [...defaults.resolve.plugins],
            modules: [srcAppPath, nodeModulesPath],
            extensions: ['.native.js', '.js', '.ejs', '.jsx', '.less', 'html', 'json', `.${platform}.js`, ...defaults.resolve.extensions],
            alias: {
                _COMPONENTS: 'js/components',
                _LIBS: 'js',
                _CONFIG: 'config',
            },
        },
    };

    return config;
};
