Anyone got citizenship without learning or speaking Swiss German language?

Hey all,

Can people get Swiss citizenship without speaking Swiss German? I was initially thinking of learning this dialect, but now I think it could be a waste of my time as different regions have different dialects. Better is to learn French which is spoken in various countries other than Switzerland. On streets or restaurants I speak standard German and the people switch to that. Is that okay for the long term?

That led me to this question - anyone got citizenship here without speaking Swiss German? Just curious.
