A UICollectionViewLayout subclass that divides sections into two responsive columns for iOS apps.
UICollectionViewSplitLayout is a custom UICollectionViewLayout subclass for iOS that arranges collection view sections into two responsive columns. It solves the problem of creating adaptive, side-by-side layouts that dynamically adjust to screen size changes, such as device rotation, without compromising performance.
iOS developers building collection views that require responsive, multi-column layouts, especially those needing efficient memory usage for large numbers of cells.
Developers choose UICollectionViewSplitLayout for its memory-efficient architecture, easy integration as a drop-in replacement for UICollectionViewFlowLayout, and fine-grained control over column ratios and section placement.
UICollectionViewSplitLayout makes collection view more responsive.

Designed to handle many cells efficiently, outperforming simpler stacking approaches, as highlighted in the README for large collections.
Easily adapts to screen changes by updating the leftSideRatio property, ideal for device rotation, as demonstrated in the GIF example.
Allows each section to be assigned to a specific column via delegate method, providing fine-grained layout customization.
Enables layout swaps without modifying data source or delegate code, promoting clean separation of concerns per the project philosophy.
Only supports two columns, making it unsuitable for more complex grid arrangements or multi-column designs beyond its scope.
Requires implementing UICollectionViewDelegateSectionSplitLayout methods for cell sizing and section placement, adding boilerplate code compared to simpler layouts.
Features like section header pinning are only supported from iOS 11 onward, limiting backward compatibility for full functionality.
