React native iOS 0.69.1 build failed when creating new project-CodePudding

I created a new project using npx react-native init MyApp --template react-native-template-typescript and then running yarn ios I'm getting build error:

The following build commands failed:
    CompileC /Users/macbookair/Library/Developer/Xcode/DerivedData/justChat-gvlyyuoxvfahekfvnoiuaatjtplq/Build/Intermediates.noindex/Pods.build/Debug-iphonesimulator/React-Codegen.build/Objects-normal/x86_64/FBReactNativeSpec-generated.o /Users/macbookair/Desktop/justChat/ios/build/generated/ios/FBReactNativeSpec/FBReactNativeSpec-generated.mm normal x86_64 objective-c   com.apple.compilers.llvm.clang.1_0.compiler
(1 failure)

I tried the following suggestions mentioned in this link:

Podfile:

require_relative '../node_modules/react-native/scripts/react_native_pods'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

platform :ios, '12.4'
install! 'cocoapods', :deterministic_uuids => false

target 'justChat' do
  config = use_native_modules!

  # Flags change depending on the env values.
  flags = get_default_flags()

  use_react_native!(
    :path => config[:reactNativePath],
    # to enable hermes on iOS, change `false` to `true` and then install pods
    :hermes_enabled => flags[:hermes_enabled],
    :fabric_enabled => flags[:fabric_enabled],
    # An absolute path to your application root.
    :app_path => "#{Pod::Config.instance.installation_root}/.."
  )

  target 'justChatTests' do
    inherit! :complete
    # Pods for testing
  end

  # Enables Flipper.
  #
  # Note that if you have use_frameworks! enabled, Flipper will not work and
  # you should disable the next line.
  # use_flipper!()
  use_flipper!({ 'Flipper' => '0.151.0' })

  post_install do |installer|
    react_native_post_install(installer)

    __apply_Xcode_12_5_M1_post_install_workaround(installer)
  end
end

Any suggestions?

CodePudding user response：

Looks like the pods from RN/FB are targeting deployment target 11.0, try to add this at the end of your Podfile so it will use the app's deployment target instead for all pods (except RCT-Folly which has to stay at 9.0 or it throw another error):

deployment_target = Gem::Version.new('12.4')
platform :ios, deployment_target

# ...

post_install do |installer|
  react_native_post_install(installer)
  # Uncomment if using a M1 Mac with XCode 12.5
  # __apply_Xcode_12_5_M1_post_install_workaround(installer)

  # target -> https://www.rubydoc.info/gems/xcodeproj/Xcodeproj/Project/Object/PBXNativeTarget
  installer.pods_project.targets.each do |target|
    case target.name
    # Ignore RCT-Folly because it only works with 9.0 as a deployment target
    when 'RCT-Folly'
      next
    else
      # Explicitly set pods deployment target for each build config to app deployment target
      target.build_configurations.each do |config|
        current_pod_target = config.build_settings['IPHONEOS_DEPLOYMENT_TARGET']
        pod_ios_deployment_target = Gem::Version.new(current_pod_target)
        if pod_ios_deployment_target <= deployment_target
          config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
        end
