Fastlane build failing due to clang error

[younusmahmood]

Hi everyone,

I've been trying to get my build up on fastlane but it seems to give me this error after I installed react-native-firebase, I know there have been some posts on this but I was hoping to find something more recent if anyone has experienced it or if there was something specific about my pod file.

[22:50:42]: ▸ ld: could not reparse object file in bitcode bundle: 'Invalid bitcode version (Producer: '1316.0.21.2.5_0' Reader: '1300.0.29.30_0')', using libLTO version 'LLVM version 13.0.0, (clang-1300.0.29.30)' for architecture arm64
[22:50:42]: ▸ clang: error: linker command failed with exit code 1 (use -v to see invocation)

I've tried pod deintegrate and pod install, removed the derived data and even added use_frameworks! :linkage => :static to my podfile. Here it is below:

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 File.join(File.dirname(`node --print "require.resolve('@react-native-community/cli-platform-ios/package.json')"`), "native_modules")

platform :ios, '12.0'

install! 'cocoapods', :disable_input_output_paths => true

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

target 'axd' do
  use_frameworks! :linkage => :static
  use_expo_modules!
  config = use_native_modules!

  use_react_native!(
    :path => config[:reactNativePath],
    :hermes_enabled => podfile_properties['expo.jsEngine'] == 'hermes'
  )

  # Uncomment to opt-in to using Flipper
  #
  # if !ENV['CI']
  #   use_flipper!('Flipper' => '0.75.1', 'Flipper-Folly' => '2.5.3', 'Flipper-RSocket' => '1.3.1')
  # end
  
  pod 'react-native-splash-screen', :path => '../node_modules/react-native-splash-screen'
  pod 'Firebase', :modular_headers => true
  pod 'FirebaseCore', :modular_headers => true
  pod 'GoogleUtilities', :modular_headers => true
  $RNFirebaseAsStaticFramework = true


  pre_install do |installer|
    $RNMBGL.pre_install(installer)
  end

  post_install do |installer|
    react_native_post_install(installer)
    __apply_Xcode_12_5_M1_post_install_workaround(installer)

    # Workaround `Cycle inside FBReactNativeSpec` error for react-native 0.64
    # Reference: https://github.com/software-mansion/react-native-screens/issues/842#issuecomment-812543933
    installer.pods_project.targets.each do |target|
      $RNMBGL.post_install(installer)
      if (target.name&.eql?('FBReactNativeSpec'))
        target.build_phases.each do |build_phase|
          if (build_phase.respond_to?(:name) && build_phase.name.eql?('[CP-User] Generate Specs'))
            target.build_phases.move(build_phase, 0)
          end
        end
      end
    end
  end

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

end

Any help with this would be much appreciated, thanks in advance.

First result has an exact hit: facebook/facebook-ios-sdk#2052

Basically, your version of Xcode is obsolete, likely because the macOS it is running on is obsolete and no longer getting updates to Xcode. Please note that react-native-firebase requires Xcode 13.3+ to build, as noted in the changelog for our v15 release:

Yup, that did the trick. Thanks!
