Developers aiming to create chat applications on iOS are encouraged to use the new Swift Chat SDK, which facilitates the implementation of features such as group messaging, threads, reactions, and typing indicators. The sample app, Team Chat, demonstrates how to use PubNub Chat on Apple platforms, including iOS, iPadOS, and macOS, with user management and online/offline presence status. Built using SwiftUI, it offers a simplified way to develop user interfaces for any Apple device. PubNub's Client State Management framework, based on ReSwift, helps maintain predictable and stable applications by managing data flow and synchronizing UI updates with real-time events. This setup allows developers to efficiently integrate rich in-app chat functionalities, leveraging PubNub's infrastructure to enhance scalability and maintainability. The project is accessible via a GitHub repository, and developers can utilize detailed documentation to further explore the integration of chat features into applications.
