更新到 Xcode 7 后遇到此问题。从命令行和 Xcode 本身构建静态框架并收到以下错误：

这似乎是have been an issue previously with framework that were using iOS-Universal-Framework，但由于我们没有使用它并且这个问题是由 Xcode 7 的更新引入的，我认为这不是我的问题的一部分。

有人在使用 Xcode 7 时遇到过这个问题吗？针对此类问题进一步调试的任何提示？

【问题讨论】：

SDK_I_AM_BUILDING.framework/Versions/A 的 No such file or directory 让我相信 Xcode 认为它正在构建一个动态库，因为我不认为静态框架使用 Versions 目录。

【解决方案1】：

这似乎是 Xcode 6 框架项目在更新到 Xcode 7 时无法正确更新的问题。

我的团队成员创建了一个新的 Xcode 7 静态框架项目，并从现有项目中复制了所有内容。然后，他们比较了两个 project.pbxproj 文件，并复制了对现有项目的任何相关更改。

有很多变化，所以在这里发布所有内容并不简单。如果您遇到此问题，我建议您完成上述过程。
