Swing weight is the combination of the racquet's length, stationary weight, and balance point. Together, these factors determine if a racquet feels light or heavy when it's in motion. High stationary weight, head-heavy balance, and a length longer than 27 inches all increase swing weight.
Swing weight is a subjective measure of how much a racquet feels like it weighs, when in motion or as you can guess when you are taking a swing at the ball. A racket that say weights 400grams can feel like it weighs only 350g when you play with it, then the swing weight would be lighter than the actual weight.
