    it seem Cocoapods issue and it resolved,
    just wait for next public release
    https://github.com/CocoaPods/CocoaPods/pull/12009

    With Cocoapods old version, you can fix this issue by edit Podfile like following

    post_install do |installer|
  installer.aggregate_targets.each do |target|
    target.xcconfigs.each do |variant, xcconfig|
      xcconfig_path = target.client_root + target.xcconfig_relative_path(variant)
      IO.write(xcconfig_path, IO.read(xcconfig_path).gsub("DT_TOOLCHAIN_DIR", "TOOLCHAIN_DIR"))
    end
  end
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      if config.base_configuration_reference.is_a? Xcodeproj::Project::Object::PBXFileReference
        xcconfig_path = config.base_configuration_reference.real_path
        IO.write(xcconfig_path, IO.read(xcconfig_path).gsub("DT_TOOLCHAIN_DIR", "TOOLCHAIN_DIR"))
      end
    end
  end
end

    I solved modifying the pod_install in this way:

    post_install do |installer|
  installer.pods_project.targets.each do |target|
  flutter_additional_ios_build_settings(target)
      target.build_configurations.each do |config|
      xcconfig_path = config.base_configuration_reference.real_path
      xcconfig = File.read(xcconfig_path)
      xcconfig_mod = xcconfig.gsub(/DT_TOOLCHAIN_DIR/, "TOOLCHAIN_DIR")
      File.open(xcconfig_path, "w") { |file| file << xcconfig_mod }
      end
  end

    end

    I kept this line of code:

    flutter_additional_ios_build_settings(target)

    because without it I have found other problems like:

        Swift Compiler Error (Xcode): No such module 'Flutter'
/Users/xxxxxxxxxx/.pub-cache/hosted/pub.dev/modal_progress_hud_nsn-0.4.0/ios/Classes/ModalProgressHudNsnPlugin.swift:0:7

    Until the fix has been published, just open a Terminal window and run

    find . -type f -exec grep -l 'DT_TOOLCHAIN_DIR' {} ; 
| while IFS= read -r file; do sed -i '' 's/DT_TOOLCHAIN_DIR/TOOLCHAIN_DIR/g' "$file"; done

    After that the error is gone and won’t return unless you run pod update or pod install again, in which case you must run that command again.
