IGListKit is a data-driven list manager and framework for iOS that decouples data models from cell logic. It serves as a wrapper for collection views, using a system of section controllers to map specific data model types to independent objects that manage the logic and sizing for list sections.
The project features a diffing algorithm library that calculates the minimal set of changes between two data collections. By using unique identifiers and equality tracking, it identifies inserts, deletes, and moves to trigger animated updates instead of full interface reloads.
The framework covers a broad range of capabilities including the rendering of diverse content types within a single list, the integration of supplementary views, and the monitoring of cell display events. It also includes proximity monitoring to notify controllers when they enter a range around the viewport to allow for proactive asset pre-loading.
