I don’t think so. The difference in the gravitational field between the bottom point of the swing arc and the top is negligible. The swing isn’t an isolated system, so you’re able to transmit force to the bar as you move around.
There’s a common explanation you’ll find online of how swings work by you changing the height of your center of mass, which is wrong, since it would imply that a swing with rigid bars wouldn’t work. But they do.

The actual explanation seems to be something to do with changing your angular momentum at specific points by rotating your body.
