A lightweight Swift framework for building extensible and performant chat applications.
Chatto is a lightweight Swift framework for building chat applications on iOS. It provides the core infrastructure needed to create performant and extensible chat interfaces, handling complex tasks like message pagination and background layout calculations. The framework is designed to be flexible, allowing developers to customize the chat experience while maintaining smooth performance.
iOS developers building chat features into their applications, particularly those who need a performant and customizable solution rather than a fully pre-built chat UI.
Developers choose Chatto for its balance of performance and extensibility—it handles heavy lifting like background calculations and pagination efficiently while allowing deep customization of the chat interface and components.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Calculates collection view changes and layouts in the background, ensuring smooth scrolling even with thousands of messages, as highlighted in the features.
Supports pagination in both directions and autoloading, efficiently handling large message histories without performance degradation.
ChattoAdditions provides ready-to-use text and photo bubbles plus an extensible input bar, allowing quick customization without reinventing the wheel.
Includes accessory view revealing by swiping and interactive keyboard dismissal, enhancing user experience out of the box.
Built on UIKit and collection views, making integration with SwiftUI projects cumbersome and requiring additional bridging efforts.
Out-of-the-box support is restricted to text and photo bubbles; video, audio, or custom message types require significant custom implementation.
Multiple version branches for different Swift versions (e.g., Swift 2.x to 5) increase maintenance complexity and risk of compatibility issues.
