Dependency ModuleMap generation error (.modulemap' not found / underlying Objective-C module not found)

[mariusjcb]

Context:

I need to import multiple versions of a specific framework (Lottie; lottie-ios) in my iOS app. For instance I'm trying to do a workaround by creating a cocoapod library for each version just to expose some wrappers over the dependency framework (Lottie). I tested it in a Example project and it works fine. I am able to run the project and it imports dependency framework (lottie-ios) but also my wrapper library (LOTTIE_3.2.1) correctly.

Problem:

To avoid framework hell I would like to find a way to "embed" each version of lottie-ios framework in my cocoapods wrapper libraries (e.g. my pod LOTTIE_3.2.1 will embed lottie-ios version 3.2.1). For this I tried cocoapods-packager but it refuses to compile. (tried with both Xcode 11.7 and Xcode 12)
