Hello @cinema8150 ,

thank you very much for reporting the issue 👍

I am analyzing this issue, and it seems like it has nothing to do with the comment, instead, AnnotationParser crashes on this line: .substring(to: max(0, lineInfo.character - 1)) while trying to evaluate spaces in front of var ageDesc: String statement. Seems like lines are miscalculated, and an empty line is passed to AnnotationParser's inlineFrom.

I'll keep you posted, I plan to resolve this today.

Finished investigation: this is actually fixed in #1171 which seemed to be unrelated, but it is about how lines are parsed. Before they were against Swift grammar, and now they are parsed line SwiftSyntax would parse them.
