A Swift client for Rails ActionCable, enabling real-time WebSocket communication in iOS/macOS apps.
ActionCableClient is a Swift library that provides a native client for Rails ActionCable, the WebSocket server in Rails 5+. It enables iOS and macOS apps to establish real-time, bidirectional communication with Rails backends, abstracting WebSocket complexities for seamless integration of live features like chat or notifications.
iOS and macOS developers building Swift applications that require real-time communication with Rails backends using ActionCable.
Developers choose ActionCableClient for its dead-simple API that mirrors Rails ActionCable conventions, reducing boilerplate and handling WebSocket management automatically, making real-time feature implementation straightforward.
ActionCable is a new WebSocket server being released with Rails 5 which makes it easy to add real-time features to your app. This Swift client makes it dead-simple to connect with that server, abstracting away everything except what you need to get going.

The README shows easy setup with a URL and headers, plus callbacks like onConnected and onDisconnected, abstracting WebSocket complexities.
Provides a create method for channels with identifiers and auto-subscription, mirroring Rails conventions for straightforward real-time communication.
Offers closures for onReceive, onSubscribed, and other events, making it intuitive to handle server interactions without boilerplate code.
Allows setting custom headers like Authorization, as shown in the usage section, enabling seamless server-side authentication with Rails.
Tightly coupled to Rails ActionCable; switching to a different backend protocol requires significant code changes and loses abstraction benefits.
Relies on Starscream for WebSocket implementation, adding a layer that may introduce compatibility issues or require updates independent of this library.
Main documentation is on a separate wiki, not in the README, which can be less accessible and might not be as up-to-date or comprehensive.
