Pageboy

Implements PageboyViewControllerDataSource with clear methods like numberOfViewControllers and viewControllerFor, reducing boilerplate compared to UIPageViewController's complex data source.

Provides reliable delegate callbacks such as willScrollToPageAtIndex and didScrollToPage, offering precise control over page transitions and better error handling than native UIPageViewController.

Supports on-the-fly insertion and deletion of pages using insertPage and deletePage functions, with configurable update behaviors similar to UITableView.

Includes built-in infinite scrolling, auto-scrolling via PageboyAutoScroller, and custom animated transitions, which are not easily achievable with standard UIPageViewController.
