Also, word is that 3 point landings are NOT recommended due to an unpredictable stall and the canopy blanking the vertical surfaces.
It's actually due to the way the gear wells face the relative wind - before the plane stalls, there is a sudden, significant increase in drag. Also, at least one Swifter has taken an electronic level/protractor type of rig and measured the stall AoA and the 3-point angle. The stall happened about 3 degrees lower than the 3-point attitude.
Thing is, the Swift is the most-modified airplane out there. For example, they came from the factory with either 85hp (GC-1A) or 125hp (GC-1B) and while the most common powerplant on them these days is the 145hp Continental O-300D, there are plenty of them out there at 150, 160, 180, 200, and 210hp as well. The really high-powered ones are the ones that have rudder authority issues with a left crosswind, but there is also some sort of rudder mod on some Swifts. You really can't find a "stock" Swift any more, and many have a dozen or more STC's or 337's. They came with yokes, many now have sticks. A bubble canopy is another common mod. C152 seats are a popular addition. There are different-sized wheels, retractable tailwheels, different wingtips, different landing lights, P-51 gear doors, several different aux fuel tank setups, you name it.
Beautiful airplanes though, and the fact that there are still quite a few flying (and in demand) tells me that the difficulties with the type are outweighed by its good qualities.
The owners seem to be very dedicated as well.
