最近我更新了Xcode 15和IOS 17，我在Xcode中遇到了错误“DT_TOOLCHAIN_CHAIN”和代码签名问题。
我需要合并这两个到我的post_install部分，但每次我把它们放在一起，我会遇到'Flutter/Flutter. h'文件找不到
我是Podfile的新手，不知道如何调试，我将如何合并这两段代码？

post_install do |installer|
  installer.pods_project.targets.each do |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

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['EXPANDED_CODE_SIGN_IDENTITY'] = ""
      config.build_settings['CODE_SIGNING_REQUIRED'] = "NO"
      config.build_settings['CODE_SIGNING_ALLOWED'] = "NO"
     end
  end
end
