Nested projects, is there a way to get the product of a nested framework project ?

I have a project framework inside my app project.
I would like to add the framework product in embedded binaries of the the app project with Xcodeproj

For this I need to get the product reference of the nested framework project.

In the project.pbxpoj I can see there are 2 "Products" group, one for the app, one for the framework. But I can't find a way to access the framework "Products" group with the api.

`project.groups` returns only app groups
`project.products` returns only products of the app

Is there a way to get this data ?

Start by tracing the project.groups and project.products APIs and how nested framework projects are represented in the project.pbxproj. Done means the API provides a way to access the nested framework project's Products group or product reference for embedding in the app.
