一、Xcode 15 linking error

type argument ‘nw_proxy_config_t‘ is neither an Objective-C object nor a block type

nw_proxy_config_t这个属性说iOS17才出现的，需要忽略这个属性

结合以上分析可知，解决当前问题的关键在于 -DOS_OBJECT_USE_OBJC=0 编译器标志

通过post_integrate hook修改已经生成的Pods.xcodeproj，移除-DOS_OBJECT_USE_OBJC=0编译器标志。至于为什么不用post_install hook，那是因为必须要在项目写入完成后才能修改，否则会被覆盖从而导致修改失败。

post_integrate do |installer|
compiler_flags_key = 'COMPILER_FLAGS'
project_path = 'Pods/Pods.xcodeproj'

project = Xcodeproj::Project.open(project_path)
project.targets.each do |target|
  target.build_phases.each do |build_phases|
    if build_phases.is_a?(Xcodeproj::Project::Object::PBXSourcesBuildPhase)
      build_phases.files.each do |file|
        if !file.settings.nil? && file.settings.key?(compiler_flags_key)
          compiler_flags = file.settings[compiler_flags_key]
          file.settings[compiler_flags_key] = compiler_flags.gsub(/-DOS_OBJECT_USE_OBJC=0\s*/,'')
        end
      end
    end
  end
end
project.save()

end

补充:
如果遇到类似这样的报错：Sandbox:rsync deny(1) file-write-create …
将User Script Sandboxing设置为NO即可：

二、unary_function

No template named 'unary_function' in namespace 'std'; did you mean '__unary_function'?
