Courier Inbox iOS SDK 5.7.3 – Improved Reliability and New Listener API

Courier has released version 5.7.3 of its iOS SDK, which enhances the performance, reliability, and flexibility of the Courier Inbox for in-app notifications. Key improvements include stronger socket connection handling for reliable real-time delivery, a new threading model with CourierActor to boost performance by running SDK functions off the main thread, and a fully rebuilt inbox datastore for improved message and event management. The update simplifies listener events with the onMessageEvent callback for easier custom UI development and includes additional unit and integration tests to ensure stability and support future updates. Additionally, Courier has introduced innovations such as WhatsApp Typing Indicators, Toasts for In-App Product Notifications, and an AI-powered MCP server for notification development, emphasizing seamless integration and enhanced user experience across its platforms.
