    I got this error after upgrading to Mac OS Sonoma. After trying dozens of tricks, I uninstalled everything and tried to delete all the hidden files. Then I reinstalled Xcode, Flutter and Visual Studio Code, following precisely the guide on the Flutter site. It worked for me.

    Try adding this in your podfile:

    xcode_base_version = `xcodebuild -version | grep 'Xcode' | awk '{print $2}' | cut -d . -f 1`

  post_install do |installer|
    installer.pods_project.targets.each do |target|
      target.build_configurations.each do |config|
        config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'
        # For xcode 15+ only
         if config.base_configuration_reference && Integer(xcode_base_version) >= 15
          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
  end

    If you already have a post_install do |installer|, add only the if condition along with the end.
