"Add Context" menu doesn't show workspace files

[pinkjuice66]

Describe the bug
The "Add Context" menu in GitHub Copilot for Xcode is failing to display any files from my workspace. My workspace is primarily organized using Xcode's built-in group feature, and it appears Copilot cannot properly search files when the workspace is structured this way.

While I haven't thoroughly investigated the root cause, I suspect the issue might be related to the parsing logic for contents.xcworkspacedata, specifically the WorkspaceFile.getSubprojectURLs(workspaceURL: URL, data: Data) function, which doesn't seem to be working as expected.

Here's a sample contents.xcworkspacedata that Copilot seems to have trouble parsing

<?xml version="1.0" encoding="UTF-8"?>
<Workspace
   version = "1.0">
   <Group
      location = "group:Group1"
      name = "Group1">
      <Group
         location = "group:Group2"
         name = "Group2">
         <Group
            location = "group:SomeProject3"
            name = "SomeProject3">
            <FileRef
               location = "group:SomeProject3.xcodeproj">
            </FileRef>
            </Group>
         </Group>
      </Group>
   </Group>
</Workspace>

My observation is that the WorkspaceFile.getSubprojectURLs(workspaceURL: URL, data: Data) function only strips the 'group:' prefix. This indicates it might not be considering the full parent group path, which is crucial for resolving nested files.

Versions

• Copilot for Xcode: 0.36
• Xcode: 16.2
• macOS: 15.4

Steps to reproduce

1. Set up your Xcode workspace using Xcode groups.
2. Open this workspace in Xcode.
3. Attempt to use the "Add Context" menu from the GitHub Copilot for Xcode extension.
4. Observe that no files from the workspace are listed.
