In circular motion there must be a centripetal force directed the center. At the bottom of the swing trajectory we can pretend you are in uniform circular motion, so the net force points toward the center of the circle. Therefore, the swing must exert a force on you than the earth does in the downward direction. So, your apparent weight is your true weight.
