Communication, Contacts & Messaging

These frameworks let your app access the user's contacts and participate in the system's communication channels for calls, messaging, and shared experiences. They provide programmatic and UI-based access to contact records, integration with the system call interface for VoIP and push-to-talk, composition and filtering of messages, and coordination of SharePlay sessions and content shared in Messages. Each capability is gated by user permission and surfaced through the standard system interfaces.
