My current project has a lot of modularisation and these modules are outside of the directory where my xcodeproj and xcworkspace is. Copilot for Xcode doesn't show files in these modules when I wanted to add more context. When I moved these folder in to the project directory, it start appear on the context selection.

So it would be really cool if Copilot for Xcode observes files in parent directories or at least a field that we can provide a directory for context search would be amazing.
