Is there a way to get Xcode 13 to show file extensions in the Project Navigator? Actually in all the places that Filenames are shown in the UI (window title, pane bar, navigators)?
Xcode 13 is hiding the extensions; for C++; Obj-C, and dext projects, that is very confusing because the extension is the only thing that distinguishes between multiple files with the same base name.
Is there a hidden preference available to restore the old behavior?
Please see the Xcode 13 Release Notes:
By default, the project navigator hides file extensions and document tab titles. Configure this behavior in Xcode’s general preferences.
