React-native-firebase: [iOS] Build target RNFBApp failed when use use_frameworks!

Issue

Hi, I have issue when build target RNFBApp on iOS

Undefined symbols for architecture x86_64:
"_OBJC_CLASS_$_GULAppEnvironmentUtil", referenced from:
objc-class-ref in FirebaseCore(FIRBundleUtil.o)

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

But if I remove use_frameworks! in Podfile then build successful.

I fixed it with adding this at the end of Podfile

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if ['RNFBApp', 'RNFBMessaging'].include?(target.name)
      target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'GoogleUtilities'})
      end
    if ['RNFBCrashlytics'].include?(target.name)
      target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'Fabric'})
      target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'Crashlytics'})
      end
  end
end

but I still face some issues regarding initialization of Firebase

I managed most problems by adding system_frameworks:

` post_install do |installer_representation|

  installer_representation.pods_project.targets.each do |target|
    if ['RNFBApp', 'RNFBMessaging', 'RNFBCrashlytics', 'RNFBDatabase'].include?(target.name)
      target.add_system_framework(installer_representation.pods_project.targets.find{|target| target.name == 'GoogleUtilities'})
    elsif target.name.eql?('RNFBAnalytics')
      target.add_system_framework(installer_representation.pods_project.targets.find{|target| target.name == 'FirebaseAnalytics'})
      target.add_system_framework(installer_representation.pods_project.targets.find{|target| target.name == 'GoogleAppMeasurement'})
      target.add_system_framework(installer_representation.pods_project.targets.find{|target| target.name == 'nanopb'})
      target.add_system_framework(installer_representation.pods_project.targets.find{|target| target.name == 'GoogleUtilities'})
    end
    if ['RNFBCrashlytics'].include?(target.name)
      target.add_system_framework(installer_representation.pods_project.targets.find{|target| target.name == 'Fabric'})
      target.add_system_framework(installer_representation.pods_project.targets.find{|target| target.name == 'Crashlytics'})
      end
    if ['RNFBDatabase'].include?(target.name)
      target.add_system_framework(installer_representation.pods_project.targets.find{|target| target.name == 'GoogleUtilities'})
      target.add_system_framework(installer_representation.pods_project.targets.find{|target| target.name == 'FirebaseDatabase'})
      target.add_system_framework(installer_representation.pods_project.targets.find{|target| target.name == 'leveldb'})
      end
  end

end`

but it doesn't work for FirebaseDatabase:

Here is the same with this podfile config:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if ['RNFBApp', 'RNFBMessaging' ].include?(target.name)
      target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'GoogleUtilities'})
    elsif ['RNFBCrashlytics'].include?(target.name)
      target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'Fabric'})
      target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'Crashlytics'})
    elsif target.name.eql?('RNFBAnalytics')
      target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'FirebaseAnalytics'})
      target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'GoogleAppMeasurement'})
      target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'nanopb'})
      target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'GoogleUtilities'})
    elsif target.name.eql?('RNFBPerf')
      target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'FirebasePerformance'})
      target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'GTMSessionFetcher'})
      target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'GoogleToolboxForMac'})
    end
  end
end

IOS Native initialization in appDelegate seems to failed cause JS thread throw exception....

I've got this in Xcode logs:

NB: Android works fine

Thanks a lot, @Aurelienlajoinie, it works for me!

[romanbarzyczakgelato]

Do you have any solution for FirebaseDatabase ?

[skullet]

I'm experiencing this error as well. I need to use Mapbox iOS SDK which requires use_frameworks!, so a work around or fix for this issue would help. To manually initialize the FirebaseDatabase do we just call initialiseApp()?

[llaine]

Getting the same issue with Firebase initialisation after adding the post_install hook.

[Aurelienlajoinie]

I manage to build my app without using the podfile postinstall script and i got no error at launch on iOS.
I turn static_framework from podspec to true for each used package (using patch package)

Example for Analytics:

diff --git a/node_modules/@react-native-firebase/analytics/RNFBAnalytics.podspec b/node_modules/@react-native-firebase/analytics/RNFBAnalytics.podspec
index 0e09692..d865ab5 100644
--- a/node_modules/@react-native-firebase/analytics/RNFBAnalytics.podspec
+++ b/node_modules/@react-native-firebase/analytics/RNFBAnalytics.podspec
@@ -25,5 +25,5 @@ Pod::Spec.new do |s|
   s.dependency          'React'
   s.dependency          'Firebase/Core', firebase_sdk_version
   s.dependency          'RNFBApp'
-  s.static_framework    = false
+  s.static_framework    = true
 end

What does the static_framework attribute ? Is it a real solution to do that ?

Thanks in advance for your help :)

Hi still having a similar issue when trying to install react-native-firebase/analytics 6.3.1 on RN 0.61.5. I have added that post_install script but have had no luck. Anyone else facing this issue??

Hi still having a similar issue when trying to install react-native-firebase/analytics 6.3.1 on RN 0.61.5. I have added that post_install script but have had no luck. Anyone else facing this issue??

I had a similar issue because I use abstract_target for all of my schemas. My solution was to move use_native_modules to regular targets, so it looks like this:

abstract_target 'HomeisShared' do    
  // my shared dependencies go here

  target 'HomeisMobile' do
    use_native_modules!
  end

  target 'HomeisMobileStage' do
    use_native_modules!
  end

  target 'HomeisMobileDev' do
    use_native_modules!
  end
end  

Hope this helps

If you use RNFBAuth, add it like RNFBAnalytics:

elsif ['RNFBAnalytics', 'RNFBAuth'].include?(target.name)
       target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'FirebaseAnalytics'})
       target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'GoogleAppMeasurement'})
       target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'nanopb'})
       target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'GoogleUtilities'})

You might not need to add above 4 frameworks for RNFBAuth, but I don't have time to test :D

If you use another RNFB and dont know framework to add:*
See the error and grep the package name (eg: GULAppEnvironmentUtil)
==> Then google with that package name, you might find the needed framework:

I found that this workaround can fix the issue too:
https://github.com/invertase/react-native-firebase/issues/3253#issuecomment-595022962

If it change to static_frameworks. You don't need to fix this anymore:

v6.4.0 has been released which now has a flag to toggle using RNFirebase as a static framework: https://rnfirebase.io/#allow-ios-static-frameworks
