A custom UICollectionViewLayout that enables peek behavior for previous and next items in iOS collection views.
MSPeekCollectionViewDelegateImplementation is a Swift library that adds a custom paging behavior to UICollectionView, allowing adjacent items to peek into view. It solves the need for modern iOS app designs where horizontal scrolling sections are embedded within vertical layouts, providing visual cues for scrollable content.
iOS developers building apps with complex collection view layouts that require horizontal scrolling sections with peek previews, especially those using UIKit and Swift.
Developers choose this library because it offers a simple, non-invasive integration without requiring inheritance from UICollectionViewController, provides extensive customization options, and uses a robust custom layout to reduce bugs.

Uses a custom UICollectionViewLayout for peeking logic, which the README notes reduces bugs and simplifies integration compared to previous delegate-based hacks in version 3.0.0.
Allows fine-tuning of cell spacing, peek width, and scrolling limits, enabling precise control over UI behavior as demonstrated in the initialization options.
Automatically handles vertical scrolling directions by positioning cells correctly, making it versatile for different layout needs without extra code.
Provides functions like scrollToItem and delegate access to currentIndex, enhancing interactivity and control over navigation.
Version 3.0.0 requires migration steps from v2, indicating significant architectural shifts that could disrupt existing projects and introduce instability.
Requires explicit calls in scrollViewWillEndDragging and other delegate methods, adding complexity and potential for integration errors.
Lacks built-in support for dynamic item sizes, accessibility enhancements, or handling nested scrolling conflicts, which might require additional work.
