Thank you for your question, Tom. Although a positive diagnosis is possible with only a photo of one upper leaf, it would appear that your plant is infected with scab, described here: https://pnwhandbooks.org/plantdisease/host-disease/apple-malus-spp-scab. This photo from another Extension resembles your plant's leaf: https://apps.extension.umn.edu/garden/diagnose/plant/fruit/apple/leavesspots.html
I suggest that you submit a sample to the OSU Plant Clinic to be certain: https://bpp.oregonstate.edu/plant-clinic/submit-sample/how-submit-plant-materials
Good luck!
