A data-driven UICollectionView framework for building fast and flexible lists in iOS apps.
IGListKit is a data-driven UICollectionView framework developed by Instagram for building fast, flexible, and maintainable lists in iOS and tvOS apps. It solves the complexity of manually managing UI updates by automatically calculating and applying changes when data changes, making it perfect for dynamic content like social media feeds. The framework provides a reusable architecture that simplifies handling multiple data types within a single collection view.
iOS and tvOS developers building complex, data-heavy list interfaces such as social feeds, product catalogs, or messaging apps where performance and maintainability are critical.
Developers choose IGListKit because it eliminates error-prone manual UI updates, provides a tested and scalable architecture used at scale by Instagram, and offers full Swift interoperability while being built on battle-tested Objective-C foundations.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Eliminates error-prone manual calls to performBatchUpdates() or reloadData() by automatically diffing data changes, a core feature highlighted in the README's main points.
Promotes maintainable code with reusable cells and sections, as emphasized in the philosophy section for better component design.
Supports multiple data types within a single collection, allowing seamless mixing of different kinds of data, a key feature listed in the README table.
Used in production by Instagram with comprehensive unit test coverage, ensuring robustness for large-scale apps, as noted in the fully tested feature.
Written in Objective-C but fully supports Swift, making it accessible for modern iOS development teams, as specified in the interoperability support.
Being written in Objective-C can introduce complexity for Swift-only teams, requiring bridging and familiarity with older APIs, despite the interop support.
The data-driven approach and diffing algorithms demand a deep understanding of UICollectionView concepts, which can be overwhelming for developers new to this architecture.
Primarily focused on iOS and tvOS, with macOS support only for diffing components, making it unsuitable for cross-platform or web-based projects.
For basic lists without dynamic updates, the framework adds unnecessary complexity and setup time compared to standard UITableView or UICollectionView.
