Answer 1

I was able to find temp fix with adding

#include <functional>
to
ios/Pods/Flipper/xplat/Flipper/FlipperTransportTypes.h
may be an flipper needs an upgrade

Edit: can confirm flipper repo has this patch facebook/flipper@b3dcdb8 If you want change in pod file so use

Answer 2

• Modify FlipperTransportTypes.h and add bellow code to line 9

  #include <functional>
  

• If you still want to use flipper, then modify your Podfile & add this to your post_install.

  post_install do |installer|
    installer.pods_project.targets.each do |target|
      if target.name == 'Flipper'
        file_path = 
  'Pods/Flipper/xplat/Flipper/FlipperTransportTypes.h'
        contents = File.read(file_path)
        unless contents.include?('#include <functional>')
          File.open(file_path, 'w') do |file|
            file.puts('#include <functional>')
            file.puts(contents)
          end
        end
      end
    end
  end
