After converting all groups to folders, I encountered an issue.

Xcode 16 defaults to using folders, so I converted all project groups to folders. After doing this, I encountered an error message every time I built my project.

I have already attempted the following:

• Updated Rswift to the latest version 7.6.0
• Cleaned the project
• Deleted derived data

Can anyone help with this situation? Thanks!

Thanks for your report.

I just release Rswift version 7.6.1 which should no longer crash on your project.

Note that we do not yet support resources in folders. This is something we're working on, but currently only resources in groups are listed under R.*

Thank you for the quick response. It seems that projects using folders currently need to find alternative solutions.
