Hello,
Based on the picture I can't really tell what your tree might have. I do see some white, but I can't tell if it's insect (could be wooly aphid) or the natural hairs that young shoots of many apples have. If it easily wipes off then it's probably some pest or disease.
Check out this link about wooly aphids to see if it fits what you might have.
