RN xcode升级13后报 ‘atomic_notify_one＜unsigned long＞‘ is unavailable

现象：RN在xcode 12正常，升级13后报 'atomic_notify_one<unsigned long>' is unavailable

方法1 

在podfile添加；

post_install do |installer|

    flipper_post_install(installer)

    ## Fix for Flipper-Folly on iOS 14.5

      find_and_replace("Pods/Flipper-Folly/folly/synchronization/DistributedMutex-inl.h",

        "atomic_notify_one(state)", "folly::atomic_notify_one(state)")

      find_and_replace("Pods/Flipper-Folly/folly/synchronization/DistributedMutex-inl.h",

        "atomic_wait_until(&state, previous | data, deadline)", "folly::atomic_wait_until(&state, previous | data, deadline)")

  end

def find_and_replace(dir, findstr, replacestr)

  Dir[dir].each do |name|

      text = File.read(name)

      replace = text.gsub(findstr,replacestr)

      if text != replace

          puts "Fix: " + name

          File.open(name, "w") { |file| file.puts replace }

          STDOUT.flush

      end

  end

  Dir[dir + '*/'].each(&method(:find_and_replace))

end

然后删除pods目录再执行pod install解决
