    Step 1

    find Hermes code in the pod file and disable it

    use_react_native!(
    :path => config[:reactNativePath],
    # to enable hermes on iOS, change `false` to `true` and then install pods
    :hermes_enabled => false
                    
  )

    Add the following block at the end of the podfile

      use_flipper!({ "Flipper-DoubleConversion" => "1.1.7" })

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

    run below comand in ios

    $ sudo gem install cocoapods-deintegrate cocoapods-clean
$ pod deintegrate
$ pod clean
$ pod install

    Add this code to your Podfile inside post_install and install pods again

    installer.pods_project.targets.each do |target|
       target.build_configurations.each do |config|
         config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['$(inherited)', '_LIBCPP_ENABLE_CXX17_REMOVED_UNARY_BINARY_FUNCTION']
       end
     end

    for example my podfile

      post_install do |installer|
    react_native_post_install(
      installer,
      # Set `mac_catalyst_enabled` to `true` in order to apply patches
      # necessary for Mac Catalyst builds
      :mac_catalyst_enabled => false
    )
    installer.pods_project.targets.each do |target|
           target.build_configurations.each do |config|
             config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['$(inherited)', '_LIBCPP_ENABLE_CXX17_REMOVED_UNARY_BINARY_FUNCTION']
           end
         end
  end
end
