While making ARKit object detection application, the scanned object(ARReferenceObject) is 5~20MB for detecting an object smoothly. Is there a way to reduce this size? Why is it needed? I have more than 200 objects to detect. and if an object takes 5MB, then almost 1GB will be occupied only for my application, which seems not appropriate.

UIPageViewControllerDelegate provides the following function: func pageViewController(_ pageViewController: UIPageViewController, didFinishAnimating finished: Bool, previousViewControllers: [UIViewController], transitionCompleted completed: Bool) This gets called only when we swap pages and keep off finger. But if we swap page with one finger and hold the next page with a second finger and keep swapping (i.e. both fingers on the screen swapping pages continuously without stopping) then didFinishAnimating never gets called. If this function is designed only to get called after the transition fully finished then there should be some delegate function which gets called when 1 single page is swapped without keeping off the finger (i.e. continuous swapping). How to get this behavior from pageViewController?

I have an application which is almost 1.5GB. While detecting leaks though leaks instrument, I can't check.
