[🐛] The Swift pod FirebaseCoreInternal depends upon GoogleUtilities

[AnthonyCodeDev]

Hi, when I do pod install in my ios folder I get this error:

The Swift pod FirebaseCoreInternal depends upon GoogleUtilities, which does not define modules. To opt into those targets generating module maps (which is necessary to import them from Swift when building as static libraries), you may set use_modular_headers! globally in your Podfile, or specify :modular_headers => true for particular dependencies.

It appears when I do:
cd ios
pod install

Does anyone have an idea how to set this? I've read that you need to add use_modular_headers! or change the version of platform :ios, ‘13.4’ or whatever.

require File.join(File.dirname(`node --print "require.resolve('expo/package.json')"`), "scripts/autolinking")
require File.join(File.dirname(`node --print "require.resolve('react-native/package.json')"`), "scripts/react_native_pods")

require 'json'
podfile_properties = JSON.parse(File.read(File.join(__dir__, 'Podfile.properties.json'))) rescue {}

ENV['RCT_NEW_ARCH_ENABLED'] = podfile_properties['newArchEnabled'] == 'true' ? '1' : '0'
ENV['EX_DEV_CLIENT_NETWORK_INSPECTOR'] = podfile_properties['EX_DEV_CLIENT_NETWORK_INSPECTOR']

use_autolinking_method_symbol = ('use' + '_native' + '_modules!').to_sym
origin_autolinking_method = self.method(use_autolinking_method_symbol)
self.define_singleton_method(use_autolinking_method_symbol) do |*args|
  if ENV['EXPO_UNSTABLE_CORE_AUTOLINKING'] == '1'
    Pod::UI.puts('Using expo-modules-autolinking as core autolinking source'.green)
    config_command = [
      'node',
      '--no-warnings',
      '--eval',
      'require(require.resolve(\'expo-modules-autolinking\', { paths: [require.resolve(\'expo/package.json\')] }))(process.argv.slice(1))',
      'react-native-config',
      '--json',
      '--platform',
      'ios'
    ]
    origin_autolinking_method.call(config_command)
  else
    origin_autolinking_method.call()
  end
end

platform :ios, podfile_properties['ios.deploymentTarget'] || '13.4'
install! 'cocoapods',
  :deterministic_uuids => false

prepare_react_native_project!

target 'StarLegends' do
  use_expo_modules!
  config = use_native_modules!
  use_frameworks! :linkage => podfile_properties['ios.useFrameworks'].to_sym if podfile_properties['ios.useFrameworks']
  use_frameworks! :linkage => ENV['USE_FRAMEWORKS'].to_sym if ENV['USE_FRAMEWORKS']

  use_react_native!(
    :path => config[:reactNativePath],
    :hermes_enabled => podfile_properties['expo.jsEngine'] == nil || podfile_properties['expo.jsEngine'] == 'hermes',
    # An absolute path to your application root.
    :app_path => "#{Pod::Config.instance.installation_root}/..",
    :privacy_file_aggregation_enabled => podfile_properties['apple.privacyManifestAggregationEnabled'] != 'false',
  )

  post_install do |installer|
    react_native_post_install(
      installer,
      config[:reactNativePath],
      :mac_catalyst_enabled => false,
      :ccache_enabled => podfile_properties['apple.ccacheEnabled'] == 'true',
    )

    # This is necessary for Xcode 14, because it signs resource bundles by default
    # when building for devices.
    installer.target_installation_results.pod_target_installation_results
      .each do |pod_name, target_installation_result|
      target_installation_result.resource_bundle_targets.each do |resource_bundle_target|
        resource_bundle_target.build_configurations.each do |config|
          config.build_settings['CODE_SIGNING_ALLOWED'] = 'NO'
        end
      end
    end
  end

  post_integrate do |installer|
    begin
      expo_patch_react_imports!(installer)
    rescue => e
      Pod::UI.warn e
    end
  end
end

there is my podfile

(I had already tried quite a few things but I deleted my ios folder to start again from 0 with your advice, on mac I can't manage to emulate the app)

Does anyone have an idea how to set this? I've read that you need to add use_modular_headers! or change the version of platform :ios, ‘13.4’ or whatever.

You may read that you should use use_modular_headers! in some places but I strongly advise against it, you will be in an unsupported configuration and any related issues will be closed here.

firebase-ios-sdk, which is our underlying SDK, strictly requires use_frameworks! :linkage => :static

You need to configure that and re-install pods and rebuild. It should work. I can see in the Podfile that it's trying to configure that based on ENV or whatever, but since you are using firebase-ios-sdk and it strictly requires it, you can just hard-code it to true

Thank you so much for your reply 🙏! Frankly, I've been struggling for weeks with this problem, I searched in every direction and I couldn't find any solution. As a last hope, I turned to GitHub and in just two minutes you came up with exactly what I needed. I just applied your suggestion and it worked perfectly! 😍

Any reference for Expo powered projects? I'm facing the same issue.

Oh I was missing the whole build properties from Expo. There I was able to set useFrameworks: 'static', and it did the trick. Thanks @mikehardy!!

I had the same issue and I figured out it was missing some configs inside my Podfile:

use_react_native!(
    :path => config[:reactNativePath],
    # An absolute path to your application root.
    :app_path => "#{Pod::Config.instance.installation_root}/.."
  )

  // Those lines below fixed my problem
  pod 'FirebaseCoreInternal', :modular_headers => true
  pod 'GoogleUtilities', :modular_headers => true

[mikehardy]

@lancaluis

No, these lines:

  // Those lines below fixed my problem
  pod 'FirebaseCoreInternal', :modular_headers => true
  pod 'GoogleUtilities', :modular_headers => true

... have just created a new problem for you that you don't know about. Specifically that firebase-ios-sdk is partially written in Objective-C and partially written in Swift.

And those lines will break your build whenever one of the modules you use converts to swift.

You must remove them.

you must use use_frameworks! :linkage => :static

Or you will not be able to get any support for react-native-firebase or firebase-ios-sdk

This is documented in our installation reference on rnfirebase.io

use_frameworks! :linkage => :static

@mikehardy just came here to say I love you 🫶

Just to clarify for anyone else looking, you have to install the expo-build-properties plugin and add this plugin to your app.config.js (or app.json) -> plugins and set

['expo-build-properties', iOS: { useFrameworks: 'static' }]

fixed spelling thanks to @fgagneten's comment below. See his comment for a more complete example

[fgagneten]

In my case, @haikulabs-ai solution worked, but his comments had a typo. This is what really worked for me:

plugins: [
    "@react-native-firebase/app",
    "@react-native-firebase/auth",
    "@react-native-firebase/messaging",
     [
      "expo-build-properties",
      {
        ios: {
          useFrameworks: "static",
        },
      },
    ],
]
