Swift is an international model from Suzuki. As I know they have the same model in every countries they exist. Full option models of the car is the same thing only in every markets. The only changes may be due to some regional collaborations with local companies or locally operated international partners. But generally the specifications will be the same only.
In a cost effective market like india they may compromise in build quality of body and wheels. Other than that I can't find any difference as a car enthusiast.
