Expert Response
I suspect you had an insect feeding on the leaves early in the season. It was probably a caterpillar but it could have been a beetle or another leaf feeding pests. Early next spring you may need to spray an insecticide if you see the problem again.
For home apple grower sprays where you need to protect against insects, and diseases I recommend this short resource from the University of Kentucky https://plantpathology.ca.uky.edu/files/ppfs-fr-t-18.pdf
Ohio State has developed a good resource on home fruit tree care.
It is available from many states for free as a PDF. Here is one from Kentucky.

Purdue also has a good resource for pest control for the home gardener for both tree fruit, grapes, strawberries and raspberries.
