Comment (by michaelld):

 The SWIG transition was just over a year ago now ... August 18, 2019 ...
 https://github.com/macports/macports-
 ports/commit/0f24ea2e95211327f4905ad9f70cf43051abd986

 So yes I suppose this dependency can be removed now ... guessing if there
 were to have been an issue someone would have reported it :)
