I will add my 2 cents here (in a less scary way :-). I have encountered quite a number of fat libraries from Vendors that (for some reason) do not work the normal way by adding them to the Frameworks directory as documented by Apple. The only way we have been able to make them work is by pulling the .framekwork right into the project directory and linking the Embedded Frameworks and Link Binary with Libraries manually in Build Settings. This seem to have worked without any issues, however, as with any fat library they come with the extraneous Simulator Architectures i386 and x86_64 along with the arm architectures.
检查fat库上的架构的一个快速方法是
$ cd 'Project_dir/Project'
$ lipo -info 'YourLibrary.framework/YourLibExec`
哪个应该吐出这样的输出
Architectures in the fat file: YourLibrary.framework/YourLibExec are: i386 x86_64 armv7 arm64
这证实了你需要在iTunesConnect存档上传之前从你的框架中“修剪脂肪”(即i386和x86_64)，这是不允许这些架构的(因为它们不支持iOS)。
现在，这里所有的答案(或者至少部分答案)提供了这些出色的运行脚本，我确信它们工作得非常好，但前提是你的框架位于Frameworks目录下。现在，除非您是一个shell脚本爱好者，否则这些没有修改的脚本将不适用于我上面解释的场景。然而，有一种非常简单的方法可以从框架中摆脱i386和x86_64架构。
在项目目录中打开终端。
将目录直接更改为. framework，例如
cd YourProjectDir /志愿者项目/ YourLibrary.framework
运行如下所示的命令-
$ mv YourLibrary YourLibrary_all_archs
$ lipo -remove x86_64 YourLibrary_all_archs -o YourLibrary_some_archs
$ lipo -remove i386 YourLibrary_some_archs -o YourLibrary
$ rm YourLibrary_all_archs YourLibrary_some_archs
这里有几件事要注意-脂肪-去除必须做一次每个架构去除。Lipo不会修改输入文件，它只生成一个文件，因此您必须为x86_64和i386运行一次Lipo -remove。上面的命令只是通过首先重命名可执行文件，然后最终删除所需的arch，然后清理剩下的文件来实现这一点。就这样，你现在应该看到一个绿色的复选标记在应用加载存档上传到iTunesConnect。
Things to keep in mind : The above steps should only be done while production build, since the .framework will be stripped off the simulator architectures, builds on simulators will stop working (which is expected). In development environment, there should be no need to strip the architectures off of the .framework file since you want to be able to test on both Simulator and a physical device. If your fat library resides in the Frameworks folder in the project then please look at the accepted answer.
