pod 安装后 Xcode 8 swift pod 标头为空

我正在尝试编译一个用 swift 编写的现有 xcode 项目。该项目使用 Alamofire。我安装了 xcode 8 beta 并打开了项目。 Alamofire 有很多错误，我了解到需要更新到版本 3.2.1。

我编辑了 Podfile 并修复了版本号，然后运行pod update alamofire。不是只更新 Alomfire，而是更新了每个 Pod。这显然是一个错误。

Podfile 包含指令 use_frameworks!更新 pod 后，pods/headers 目录完全为空，没有公共或私有目录，并且项目无法构建，出现 356 个丢失文件错误。

根据此处的建议将 ALWAYS_SEARCH_USER_PATHS 的构建搜索设置更改为 no（或 yes）https://github.com/CocoaPods/CocoaPods/issues/4605#issuecomment-208822149 https://github.com/CocoaPods/CocoaPods/issues/4605#issuecomment-208822149然后删除 pod 并再次运行 pod install 没有任何反应。

stackoverflow 上有许多不同的问题提出相同的问题，但没有答案。这是我能找到的列表。

我真的需要找到解决这个问题的方法，所以如果有人能回答这个问题，我将不胜感激。

git add -A 后跟 Product -> Clean 删除了除 Alamofire 之外的所有错误。
