ComponentKit is an Objective-C++ view framework for iOS, heavily inspired by React, that takes a functional, declarative approach to building UI. It powers Facebook's News Feed, offering asynchronous layout, flatter view hierarchies via Yoga, and fine-grained view recycling for scroll performance.
Use cases
- build declarative iOS UIs inspired by React
- improve scroll performance in complex iOS feeds
- reduce view hierarchy depth and memory usage on iOS
- perform layout off the main UI thread
- build highly recyclable collection view feeds
- port React-style component thinking to native iOS
When to choose
- building large, scroll-heavy iOS apps like feeds or timelines
- you want declarative, immutable-input UI with async layout
- your team values flat view hierarchies and fine-grained recycling
- you're already in the Facebook/Instagram iOS ecosystem
When to avoid
- starting a small or simple iOS app where SwiftUI suffices
- your team is uncomfortable with Objective-C++ and C++
- you need a rapidly evolving framework with active community development
- you target platforms other than iOS
