Xcode does not have support for "sub-projects." Xcode has support for cross-project references; a referenced project is a peer of the referencing project. The only information passed between projects is at build time, and that's only the name of the configuration to build.
Understanding this should make clearer a lot of Xcode's behavior when dealing with multiple related projects. Try doing a command click to find a symbol that's defined in a sub-project. You'll be lucky if it ever finds it. If that symbol declared in a header imported by the project you're working with, its should be found in that header. It won't necessarily find the definition of that symbol in another project because, as I said above, Xcode does not have "sub-projects" — only references to peer projects.
