one of the things that surprised me as i am upgrading swiftinit.org is how many people seem to be requesting the site in languages other than english, despite the site being entirely english-only.
nearly 20 percent of “humanoid traffic” ¹ is sending HTTP headers that indicate they would rather browse the site in a language that is not english:
(even more interesting, this only counts the primary preferred language; it doesn’t count browsers that are sending things like
en-US, pt-BR;q=0.9, for example.)
with that in mind, i would like to kickstart discussions about localizations for the UI controls for swift documentation. some questions to start:
is translating UI controls valuable on its own, even if the documentation content remains in english? should the UI language always be aligned with the content language?
should UI language influence things like sorting order of symbols?
is anyone encountering actual difficulties accessing swift documentation because the rendered UI is only available in english?
if so, what languages should become the highest priority?
 traffic that does not display obvious signs of being a robot.
