Stream Chat Swift is an iOS/macOS SDK for building real-time chat and messaging applications. It provides a modular architecture separating core networking (StreamChat), UI components (StreamChatUI), and shared utilities (StreamChatCommonUI). The SDK supports features like channels, messages, reactions, threads, polls, attachments, typing indicators, and presence. It uses Combine for reactive programming, Core Data for persistence, and WebSocket for real-time communication. The repository includes demo applications, example implementations (SlackClone, MessengerClone, etc.), and extensive testing infrastructure. The SDK follows protocol-oriented programming with dependency injection via Appearance and Components providers, enabling high customization.
This repository contains the iOS client for the ntfy.sh notification service. It is a SwiftUI-based application that allows users to subscribe to topics for receiving push notifications, manage subscriptions, view notifications with attachments, and configure settings. The architecture follows a pattern similar to MVVM using ObservableObjects for state management, with Core Data for persistence and a Notification Service Extension for processing incoming notifications. Key features include Firebase Cloud Messaging integration, attachment handling (download, preview, share, save), critical alerts support, and background polling for notification synchronization. The app supports both the default ntfy.sh server and self-hosted instances.
