Definite yes on the front rack, educated guess no on the rear rack, educated guess yes on the fenders.
I got the Traveler front rack from Thor, and it fits the Swift using spacers on the eyelets (bottle cage spacers, or two of the valve stem rings that Schwalbe and probably other brands use on their Schraeder tubes) and a tiny amount of bending to line up the fork crown hole. Attach it at the eyelets first, then rotate the rack up and attach the fork crown bolt second -- it's much easier than the other way around. I posted about it in more detail over on the neverending Swift Folders thread.
As for the rear racks, you'd need seatstay clamps, but I expect they'd tilt backwards, because the Swift's seatstays are steeper than a Dahon's, so the front mounting point would be higher.
I'd be very surprised if the SKS fenders didn't fit.
