Its not woryh to compare both rides with each other. City is sedan while swift is hatch-back.
In city, you have to give up on comfort, while fuel efficiency & pick of MT city is good + its alot more roomier + trunk capacity (add a bonus of good resale value)
In swift, you have to give up on fuel efficiency + its rear leg room is also congested + as suggested by above member comfort level is almost equal in both cars i.e. bad + bad resale value. The only good thing is its Auto tranny, which is so so useful if its your daily driven car in city & it picks up like a beast.
