iOS build fails: 'FirebaseAuth/FirebaseAuth-Swift.h' file not found in React Native + FirebaseAuth setup

[Anirudh-1606]

Description

Problem

When building my React Native iOS app with Firebase Auth, the build fails with the following error:

/Users/anirudhsaladi/Documents/codebase/rural-share/RuralShareApp/ios/Pods/Headers/Private/Firebase/Firebase.h:40:15:
'FirebaseAuth/FirebaseAuth-Swift.h' file not found

Podfile (current state)
source 'https://cdn.cocoapods.org/'
platform :ios, '16.0'

require_relative '../node_modules/react-native/scripts/react_native_pods'
prepare_react_native_project!

target 'RuralShareApp' do
config = use_native_modules!

use_react_native!(
:path => config[:reactNativePath],
:hermes_enabled => true
)

rn_maps_path = File.join(dir, '../node_modules/react-native-maps')
pod 'react-native-google-maps', :path => rn_maps_path
pod 'GoogleMaps', '7.4.0'
pod 'GooglePlaces','7.4.0'

Firebase (Auth pulls Core transitively)

pod 'FirebaseCore', :modular_headers => true
pod 'FirebaseAuth', :modular_headers => true
pod 'FirebaseCoreInternal', :modular_headers => true
pod 'FirebaseCoreExtension', :modular_headers => true
pod 'GoogleUtilities', :modular_headers => true
pod 'RecaptchaInterop', :modular_headers => true
pod 'FirebaseAppCheckInterop',:modular_headers => true
pod 'FirebaseAuthInterop', :modular_headers => true

post_install do |installer|
react_native_post_install(installer)

# ensure modules are enabled across Firebase pods
installer.pods_project.targets.each do |t|
  if ['FirebaseAuth','FirebaseCore','FirebaseCoreInternal','FirebaseAuthInterop',
      'FirebaseAppCheckInterop','FirebaseCoreExtension','GoogleUtilities','RecaptchaInterop'].include?(t.name)
    t.build_configurations.each do |c|
      c.build_settings['CLANG_ENABLE_MODULES'] = 'YES'
      c.build_settings['DEFINES_MODULE'] = 'YES'
    end
  end
end

end
end

Attempts so far (none worked)

Using use_modular_headers! globally

Using use_frameworks! :linkage => :static

Manually forcing DEFINES_MODULE = YES in post_install for Firebase pods

Adding/removing modular_headers => true per pod

Cleaning DerivedData, pod deintegrate, pod install --clean-install

Adding EXCLUDED_ARCHS for simulator (Apple Silicon)

Switching between static and dynamic frameworks

Every configuration eventually leads back to the error:

'FirebaseAuth/FirebaseAuth-Swift.h' file not found

Reproducing the issue

ios % pod deintegrate
rm -rf Pods Podfile.lock ~/Library/Developer/Xcode/DerivedData
pod repo update
pod install --clean-install
open workspace and build and get the error

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

[paulb777]

See the discussion in the similar issue #12215. Recent versions of Firebase require use_frameworks! :linkage => :static or use_frameworks!

See the discussion in the similar issue #12215. Recent versions of Firebase require use_frameworks! :linkage => :static or use_frameworks!

I'm experiencing the same issue with React Native Firebase v18+ requiring use_frameworks!, but this conflicts with react-native-maps/Google Maps.

With use_frameworks! :linkage => :static:

• Firebase works ✅
• Google Maps fails with "Unsupported Swift architecture" in Google-Maps-iOS-Utils ❌

Without use_frameworks! (using :modular_headers => true):

• Google Maps works ✅
• Firebase fails with "FirebaseAuth/FirebaseAuth-Swift.h file not found" ❌

Has anyone found a working configuration for using both Firebase Auth and Google Maps together?

[ncooke3]

Have you tried use_frameworks! with no :linkage => :static or :modular_headers => true?

use_frameworks!

pod ....

Firebase pods do not support modular_headers

I maintain a build demonstrator for react-native / react-native-firebase (read as: firebase-ios-sdk) that works every time.

It starts from scratch and results may be examined at any time to see how to get a project working

https://github.com/mikehardy/rnfbdemo/blob/main/make-demo.sh

In my experience, attempting to troubleshoot the infinite variety of ways to do it wrong is a time-sink, but showing the One True Way to get it right is pretty efficient.
