ios - 嵌入在根框架中的签名子框架不起作用(Xcode 11.2.1)

Question

我有一个小型的概念验证应用程序，我试图在我的框架(AequumPOCFramework.framework)中嵌入(并签署)一个框架(Alamofire)，但是，当我尝试部署到我的设备时，它不断给出我的错误

....not valid for use in process using Library Validation: mapped file has no cdhash, completely unsigned? Code has to be at least ad-hoc signed.

如果我只是尝试部署自己的框架，而不在其中嵌入 Alamofire，那么一切正常。

部署到我的 iphone 时的完整错误是:

dyld: Library not loaded: @rpath/Alamofire.framework/Alamofire Referenced from: /private/var/containers/Bundle/Application/EDB697EB-EA15-4301-B4B6-A8FE1F0212BE/PocIOS.app/Frameworks/AequumPOCFramework.framework/AequumPOCFramework Reason: no suitable image found. Did find: /private/var/containers/Bundle/Application/EDB697EB-EA15-4301-B4B6-A8FE1F0212BE/PocIOS.app/Frameworks/AequumPOCFramework.framework/Frameworks/Alamofire.framework/Alamofire: code signature in (/private/var/containers/Bundle/Application/EDB697EB-EA15-4301-B4B6-A8FE1F0212BE/PocIOS.app/Frameworks/AequumPOCFramework.framework/Frameworks/Alamofire.framework/Alamofire) not valid for use in process using Library Validation: mapped file has no cdhash, completely unsigned? Code has to be at least ad-hoc signed.

我究竟做错了什么？

iOS 不支持嵌套框架(参见 technotes)。目前唯一合法的解决方案是将“嵌入式”框架直接链接到托管应用程序。
*XCFramework 主要是平台特定二进制文件的聚合，不幸的是与嵌入框架无关。
