I see no one has answered your question so I will take a stab at it. I don't know about the bumpy part but the pitted part could be what is known as bitter pit. If at the pitted points underneath the skin it is brown that would
be another indication that it is bitter pit. If the soil gets too acid apples will sometimes get the bitter pit. Some varieties are more prone to bitter pit. I noticed some bitter pit on some of my apples too and I am
correcting it by the addition of dolomite lime. One of my books says that it is caused as a result of calcium deficiency within the fruit and may occur even on calcium-rich soils. It says that in order to take up calcium, the
plant needs an adequate supply of moisture. If this is not available and the tree does not get sufficient calcium, small areas of cells within the developing fruit collapse and turn brown. Goodly amount of water and a good
mulch will also help prevent it.
I hope this helps your situation since Sweet Sixteen is one of my favorite apples.
