### Xcode Official Doc
Apple's current official document section [Annotate your code for visibility][1] introduces three comments: `TODO:`, `FIXME:`, and `MARK:`.
Another two comments (though not appearing in the official documentation) supported by latest Xcode version (v14.2): `!!!:` and `???:`.
Note: `!!!:` and `???:` are found to be not supported by some Xcode versions (such as v10.0) for unknown reasons.
##### Sample screenshot 1 - Xcode 14.2 + macOS 13.1 (Ventura)
