Please tell me there's something in Xcode that can convert all groups in a project to the new ‘folders’ style, and rearrange the project files, without doing it *manually*? 😅
@stroughtonsmith I have not figured it out if there is…

@stroughtonsmith haven't used synx in a long time but it worked pretty great back when I used it a couple of years ago.

Then once your Finder folders and Xcode group will match you should be able to retry the operation in Xcode to convert groups to folders without errors that time?
