'beau' is the definition.
(I know that beau can be written as swain)

I don't understand the rest of the clue.

(Other definitions for swain that I've seen before include "Young man" , "lover of literature" , "Old word for young lover" , "Male admirer" , "fancier" .)

I've seen this clue in the Sydney Morning Herald.
