Xcode File Header Macros — The Complete Reference

Companion to How to Change the Created By Header in Xcode (2026) — Noah Does Coding

Xcode stamps a header into every file you create, and there is no preference for it anywhere in the app. It reads a plist at launch and substitutes its FILEHEADER string into each new file — once, at creation, never again. Change the plist and nothing you already wrote moves.

Apple documents only a handful of these macros. The rest of this list was read out of the macro engine inside Xcode 26.6 (17F113) on macOS 26.5. If you're on a different Xcode, re-check
