How to treat fungus on Apple tree

Question

It might be mildew! Leaves withering at top of branches of small red Windsor, shrivel and die. There are lots of fruit on and I don’t want to lose them or the tree. Thanks

Please include photos. This sounds much worse than mildew! It will be hard to know exactly what is going on without seeing the damage, but for now I will post a link that will help in the meantime: https://www.gardeningknowhow.com/edible/fruits/apples/apple-tree-diseases.htm
