Xcode + Swift: Is it possible to create custom comment marks?

Question

In Swift (I'm using Swift 3 / Xcode 8 stable): is it possible to create custom comment mark/tags that can be recognized by Xcode? (and thus added to the jump bar.)

For example, aside from the // TODO:, // FIXME: or // MARK:, can we add new ones, like // OPTIMIZE:, // EVAL:, or any other custom mark?

Answer 1

Fyi, this was done in XCode 10.2.1, just in case anyone rolls past this page. Haven't tested it under XCode 8.

Funny enough was just making a //MARK: comment, and found a new trick. While you can't just to //WHATEVER: to get that showing up the same as //FIXME, etc. What you can do is this.

//MARK: WHATEVER: this also works

//MARK: ASDOESTHIS: because why not.

Screenshow also attached for proof, hope that helps.
