Preheat your oven to 350 degrees F. Spray a 2 quart baking dish with cooking spray. Set aside.
Prepare the fruit mixture by whisking together granulated white sugar, flour, cinnamon and nutmeg in a large bowl. Add cranberries and apples and gently stir to coat well. Transfer to prepared baking dish.
Prepare the topping by stirring together oats, flour, brown sugar, pecans, cinnamon and nutmeg until combined. Add melted butter and stir again until incorporated.
Evenly sprinkle topping mixture over fruit mixture. Bake approximately 50 minutes, or until edges are bubbling and fruit is tender.
