Assuming the tree is still standing in 512 years, the swing should be the same height off the ground as it was to begin with (22 in.). Trees grow out from the trunks and out and up from the tips of their branches; individual branches - and anything attached to those branches - stay in the same place, just getting longer. The only way that the tree's growth might effect the height of the swing is if the branch starts to sag under its own weight, bringing the swing a little closer to the ground.
Its about 79 meters from the ground.
