LiveCommunicationKit is the modern replacement for CXProvider that delivers rich, native conversation UIs integrated with the Lock Screen, Dynamic Island, Phone app Recents, and Siri. It provides a unified lifecycle model for audio and video conversations with a single delegate-driven action pipeline.
ā¢ Replaces the aging CallKit/CXProvider API with a more flexible framework that supports audio, video, group conversations, hold/resume, and merging out of the box
ā¢ Conversations automatically appear full-screen on the Lock Screen with contact photo/name matching, in the Dynamic Island during multitasking, and in Phone app Recents ā with zero extra UI code
ā¢ A single perform-action delegate callback handles every interaction (system UI tap, in-app button, Siri command), eliminating duplicated state management and sync bugs
