A page view controller for iOS with a bounce effect inspired by motion design.
BouncyPageViewController is a custom iOS page view controller that adds a bounce effect to page transitions. It solves the problem of static, linear page navigation by introducing physics-based animations that make scrolling between view controllers more engaging and interactive.
iOS developers building apps with page-based navigation who want to enhance user experience with fluid, interactive animations.
Developers choose it for its easy integration, customizable bounce parameters, and the ability to bring modern motion design principles to standard UIKit components without extensive custom animation code.

Implements physics-based bounce effects that make page transitions fluid and interactive, directly inspired by modern motion design principles as shown in the demo GIFs.
Allows fine-tuning of page overlap, bounce duration, and overscroll behavior through public properties like pageContentInset and pageBounceAnimationDuration, as detailed in the configuration section.
Uses closures for providing view controllers and handling scroll events, enabling easy integration and real-time UI updates via offset and progress tracking, as demonstrated in the quickstart examples.
With clear examples for queue-based view controller management, it's straightforward to add bounce effects to existing UIPageViewController setups without extensive custom animation code.
The README specifies Swift 3, which is obsolete; developers must manually update the codebase or deal with compatibility issues in newer Xcode projects, as noted in the CocoaPods installation instructions.
Focused solely on bounce effects, it lacks advanced features like built-in data source protocols, gesture customization, or support for non-linear page flows, which might require additional development effort.
Physics-based animations can introduce slight lag on older devices or in complex view hierarchies, as hinted by the overscroll behavior configuration, which might not suit performance-critical applications.
