Write a function that will check to see if your meal log (a dictionary like that in the previous exercise) is saved to the device. If it is, return the meal log. If it isn't, return an empty dictionary of type [String: Any]. The code you should use in this exercise for retrieving something saved to the device is UserDefaults. standard. dictionary(forKey: "mealLog"). This code will return an optional [String: Any]. If it returns a value, that is your meal log. If it returns nil, then no meal log has been saved. Call the function and print the return value.
