Is react-native-swift-socketio still maintained?

No, the README clearly states it's not maintained anymore, so it lacks updates and support, making it risky for production use without forking or finding alternatives.

How to set up react-native-swift-socketio in Xcode?

Follow the README steps: install via npm, add files from node_modules to Xcode, and set the Objective-C bridging header to SocketBridge.h. It's a manual process that can be tricky for beginners.

react-native-swift-socketio vs socket.io-client for React Native?

This library is iOS-only and wraps the native Swift client for better performance, while socket.io-client is cross-platform but may have overhead. Choose based on platform needs and maintenance status.

Can I use react-native-swift-socketio for Android?

No, it only supports iOS by wrapping the Swift library. For Android, you'd need a separate solution like a Java-based Socket.IO client or a cross-platform React Native library.

What are the known issues with react-native-swift-socketio?

The README mentions a non-modular header issue preventing it from being an Xcode framework, and some config options like cookies aren't supported. Setup complexity is also a common pain point.

How to force WebSockets in react-native-swift-socketio?

Use the config option 'forceWebsockets: true' in the constructor to enforce WebSocket transport, which can improve performance for real-time data compared to polling.

What is react-native-swift-socketio?

kirkness/react-native-swift-socketio is an unmaintained React Native library that provides a wrapper for the Socket.IO-Client-Swift library. It enables React Native developers to integrate real-time, bidirectional event-based communication into their iOS applications by bridging native Swift socket functionality with JavaScript. The library supports WebSockets or polling for live data updates and allows customization of connection parameters, event handling, and namespace management.

Target Audience

React Native developers building iOS applications that require real-time communication features, such as chat apps, live notifications, or collaborative tools, and who specifically need to use the native Swift Socket.IO client for performance or compatibility reasons.

Value Proposition

Developers choose this library for direct integration with the official Socket.IO Swift client, ensuring native iOS performance and adherence to the Socket.IO protocol. It offers a straightforward bridge with configurable options like reconnection attempts, polling/WebSocket forcing, and namespace management, though it is no longer maintained.

Pros & Cons

Pros

Native iOS Performance

Wraps the official Socket.IO-Client-Swift library directly, ensuring optimal socket performance and reliability on iOS devices, as highlighted in the README's integration approach.

Full Protocol Support

Adheres to the Socket.IO protocol with support for real-time event handling, configurable reconnections, and namespace management, allowing seamless bidirectional communication.

Configurable Connection Options

Offers customization like forcing WebSocket or polling, setting reconnection attempts, and path configurations, providing flexibility for different server setups.

Simple JavaScript Interface

Provides a straightforward bridge to native Swift, with methods like on, emit, and connect that mirror standard Socket.IO usage, easing integration for React Native developers.

Cons

Unmaintained Project

The README explicitly states it's not maintained, meaning no updates for bug fixes, security issues, or compatibility with newer React Native or iOS versions.

iOS-Only Limitation

Only supports iOS, forcing developers to find separate solutions for Android in cross-platform apps, which adds complexity and maintenance overhead.

Complex Manual Setup

Requires manual Xcode configuration, including adding files and setting Objective-C bridging headers, which is error-prone and not automated like modern React Native libraries.

Incomplete Feature Set

The README admits some Socket.IO options like cookies and sessionDelegate are not supported yet, limiting use cases that require advanced handshake or security configurations.
