Abstract

Chatto is an open-source Full Stack Web Development project. A lightweight framework to build chat applications, made in Swift. Chatto is a Swift lightweight framework to build chat applications. It's been designed to be extensible and performant. It is built using Swift. Key capabilities include: Calculation of collection view changes and layout in background; Supports pagination in both directions and autoloading; Message count contention for fast pagination and rotation with thousands of messsages. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building a Full Stack Web Development mini project or final-year project.

1. Introduction

Chatto is a Swift lightweight framework to build chat applications. It's been designed to be extensible and performant. Along with Chatto there is ChattoAdditions, a companion framework which includes cells for messages and an extensible input component. You can find more details about how it was implemented in our blog. See them in action!
