Duo lingo stories in Swedish
Will the Swedish language offer Duolingo stories at any time?
Possibly, but I do not think that is up to the course contributors. The stories are managed from headquarters exclusively, as far as I am aware.
If you look at the language options available for stories, they start with the most popular ones and build from there. If they ever do add a Swedish mode, then it will probably be after adding Italian, Russian, and Dutch. Japanese is unlikely since most of its learners aren't on a level high enough to comprehend stories yet.
