Preventing the white gap that appears on swiping UIPageViewController

Question

I have implemented the UIPageViewController in this manner:

GalleryViewController

Answer 1

Check definitely example here: https://github.com/dimpiax/UIPageViewControllerScrolling

But if you want to remove empty blank on swipe, you can remove bounce, for example:

for value in view.subviews {
    if let scrollView = value as? UIScrollView {
        scrollView.bounces = false
    }
}
