React-native-firebase: Undefined symbols on iOS w/ RN 0.60.3's autolinking feature

Issue

Possibly related to #2353:

I can't build my React Native 0.60.3 project with React Native Firebase 5.5.5:

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_FIRApp", referenced from:
      objc-class-ref in AppDelegate.o
  "_OBJC_CLASS_$_RNFirebaseMessaging", referenced from:
      objc-class-ref in AppDelegate.o
  "_OBJC_CLASS_$_RNFirebaseNotifications", referenced from:
      objc-class-ref in AppDelegate.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

react-native-firebease is currently the only installed package that fails in this manner.

I have cleared my Other Linker Flags settings in Xcode, which used to contain $(inherited), which with RN0.60's new autolinking feature, would generate duplicate symbols for every linked package:

duplicate symbol _OBJC_CLASS_$_RCTVibration in:
    /Users/jorisw/Projects/xxx/xxx-frontend/ios/build/xxx/Build/Products/Debug-iphonesimulator/React-RCTVibration/libReact-RCTVibration.a(RCTVibration.o)

use_frameworks! is (still?) not playing nice with this library (6.0.3) under RN 0.61.2.
I've solved it for now by linking the needed frameworks in a post_install:

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 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'})
    end
  end
end

Tried suggestion in https://github.com/invertase/react-native-firebase/issues/2354, didn't work

jorisw on 14 Jul 2019

I get the same error.

JerakRus on 14 Jul 2019

If I remove the search path of 'react-native-firebase / ios' in build settings, the error goes away, but another "RNFirebaseNotifications.h 'file not found' " appears.

JerakRus on 14 Jul 2019

I've fixed my Xcode project as follows:

Under Build Settings, change Linking -> Other Linker Flags, to only contain $(inherited).

Your build may now crash on duplicate symbols if you were already using CocoaPods before you upgraded React Native. To fix this, following the hint at https://github.com/facebook/react-native/issues/23613#issuecomment-499341062 :

Under Build Phases -> Link Binary With Libraries, remove everything but JavaScriptCore.framework, then run rm -rf Pods; pod install from your ios/ folder.

The app should now build.

Still happens to me :(

@jrnk without specifying the versions of everything you're using this advice may not be useful. use_frameworks support is in flux between rn59, 60, and 61, and the react-native-firebase version is also likely important

mikehardy on 29 Oct 2019

@mikehardy good point, I've edited the comment to reflect that (rn-fb 6.0.3 and rn 0.61.2)

jrnk on 29 Oct 2019

...and unfortunately you are completely current so it's a shame use_frameworks is still so problematic :-). One of these days...

mikehardy on 29 Oct 2019

Getting the same issue with react-native 0.61.4 and react-native-firebase 6.1.0, however @jrnk post_install trick did the job.

llaine on 6 Dec 2019

@llaine thanks for your solution, it helped me fix it for RNFBApp, but, how do I fix it for my other dependencies. I am currently using the following dependencies: ['RNFBApp', 'RNFBAuth', 'RNFBFirestore', 'RNFBStorage', 'RNFBDynamicLinks', 'RNFBPerf', 'RNFBAnalytics', 'RNFBCrashlytics'] ?

p.s How do I find out which system frameworks I need to add to each target, so I can fix it myself in the future if I decide to use other frameworks?

Hello,
I'm using this on my project:

  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 == 'FirebaseSwizzlingUtilities'})
      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 == 'GoogleDataTransport'})
      target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'GoogleDataTransportCCTSupport'})
      target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'GoogleToolboxForMac'})
      target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'GoogleUtilities'})
      target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'Protobuf'})
      target.add_system_framework(installer.pods_project.targets.find{|target| target.name == 'nanopb'})
    end
  end

Build is ok but i've an error at startup with FIRApp initialization and don't know if the problem come from pod install :s ([FIRApp configure] is ok in appDelegate.m file)

Aurelienlajoinie on 7 Jan 2020

@Aurelienlajoinie I'm having the same exact issue.
We have to use use_frameworks! for other dependencies.
We are able to build using the add_system_framework solution described above, but we see a crash on init with [Firebase/Core][I-COR000005] No app has been configured yet.

Config file is correctly included and the library is initialized as well with
if ([FIRApp defaultApp] == nil) { [FIRApp configure]; }

No dice.

mikem3d on 2 Mar 2020

@mikem3d i was able to fix this using this Podfile:

use_frameworks!
 ....

target 'myTarget' do
  use_native_modules!

pod 'FBLazyVector', :path => "../node_modules/react-native/Libraries/FBLazyVector"
  pod 'FBReactNativeSpec', :path => "../node_modules/react-native/Libraries/FBReactNativeSpec"
  pod 'RCTRequired', :path => "../node_modules/react-native/Libraries/RCTRequired"
  pod 'RCTTypeSafety', :path => "../node_modules/react-native/Libraries/TypeSafety"
  pod 'React', :path => '../node_modules/react-native/'
  pod 'React-Core', :path => '../node_modules/react-native/'
  .....
end

pre_install do |installer|
  installer.pod_targets.each do |pod|
    if pod.name.start_with?('RNFB')
      def pod.build_type;
        Pod::Target::BuildType.static_library
      end
    end
  end
end

Hope it can help you :)

Aurelienlajoinie on 2 Mar 2020

🎉1 👍1

@Aurelienlajoinie that worked! should be pinned and added to documentation!
def pod.build_type; Pod::Target::BuildType.static_library end

mikem3d on 2 Mar 2020

I think getting it to work with use_frameworks in general could use a full documentation page that consolidates all the known-required workarounds - it is a huge source of issue traffic here and could help lots of people if someone wanted to start a gist that grouped them all together?

mikehardy on 2 Mar 2020

@Aurelienlajoinie that worked for me just for another library, not for firebase. Thank You!!!
