Layer the chicken at the bottom of the slow cooker. Add the garlic, onion, diced tomatoes, sliced peaches, garbanzo beans, dried apricots, and spices—cumin, ginger, cinnamon, coriander, and cayenne pepper. Pour in the chicken broth, ensuring everything is covered. Set the slow cooker to Low and let it cook for 5 hours, allowing the flavors to meld and the chicken to become tender.
