editing Makefile in Xcode editor

I want to edit a Makefile using the Xcode editor (part of my project). I can create and edit the file, but Xcode seems to assume it’s a Swift file — it applies Swift syntax highlighting, and I get incorrect suggestions while editing.

I tried changing the “Open As” option from “Source Code,” but there’s no “Plain Text” option available.

I’m using Xcode 16.4.

I’ve seen suggestions like: • Using an external editor (which works, but feels clunky), • Renaming the file to something like Makefile.txt (but that breaks standard CLI use, e.g. make expects Makefile).

Not too happy with either workaround — did I overlook a proper way to just edit a Makefile in Xcode without confusion?

Any suggestions appreciated!

Thanks, Lourens

Looks fine here.

One thing to look at is if the type of the file is set to makefile in Xcode. You can find that in the File Inspector, pictured here.
