Cannot select source file to include in chat window via 📎 file list button when the build is out of source

[ebernardatdxo]

Describe the bug
Our project is configured to have the build directory out of the source directory.
And the xcode project is generate by cmake.
The tree is like that :

    project_src
    project_build
        project.xcodeproj
        bin 
        etc ...

In this configuration copilot don't list file from the source directory.
It only list file from the build directory.

Versions

• Copilot for Xcode: [e.g. 0.32.0]
• Xcode: [e.g. 16.2]
• macOS: [e.g. 15.3.2]

Steps to reproduce
clic on 📎 and only files inside the project_build appear.

Logs

Additional context

I got same issue and I found why copilot couldn't find any files.

CopilotForXcode can read only one Project.
If your Project has another project files in project directory, copilot can't read any files.

It's example.

If one Project	If Project has another Projects in directory
