For example ask Apple to do something and let them sort that out using their employee. Or some web site (I use one particular to help me).
Swift is a language like lisp or clojure. You may look at its architecture etc to see whether it is built in issue (lisp is easy but its library is not, say). Or it is really just a hiring issue.
Or may I just ask how to address the original question if it is just language lack of good doc.
