I am not sure I understand the following:

Embedable Xcode projects:
For various complex reasons, C language targets are not mapped to "real" framework targets in the generated Xcode project. In practice, this means that the "defines module" and "enable modules" build settings are turned off in the generated framework target. This causes issues when trying to use the generated project as a subproject.

The issue is resolved for C language targets that have an umbrella header. To create an umbrella header, place a file named <targetname>.h inside the include/ directory of that target and include all the public headers in the umbrella header.

I described my situation/understanding in more details in a new post here.
