I have a small proof-of-concept app, where I am trying to embed (and sign) a framework (Alamofire) inside of my framework (AequumPOCFramework.framework), however, when I try to deploy to my device, it keeps giving me the error

....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.

If I just try to deploy my own framework, without having Alamofire embedded in it, everything works fine.

The complete error at deploy to my iphone is:

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.

Code has to be at least ad-hoc signed.

What am I doing wrong?

Nested frameworks are not supported on iOS (see technotes). The only legit solution at the moment is to link "embedded" frameworks directly to a hosting app.

* XCFramework is mainly an aggregation of platform specific binaries' and has nothing to do with embedding frameworks unfortunately.
