This is caused by a conflict between the Wikimedia-internal language code als (Alemannisch) and ISO 639-3 where als is assigned to Albanian (Tosk). The iOS Locale framework follows ISO 639-3, so it returns the wrong localized name. A possible fix: add "altISOCode": "gsw" to the als entry in wikipedia-languages.json and use that for the Locale lookup in WikipediaLookup.swift. This would also resolve T414588, since the same altISOCode addition provides the missing gsw→als mapping needed by MWKLanguageLinkController.
