Definition

CXTransaction is the CallKit container object used to group one or more call actions into a single transactional request sent to the iOS telephony system.

CallKit processes:

• transactions
• not standalone actions

Core Concept

A CXAction represents:

something the app wants to do.

Examples:

• start call
• end call
• mute call
• hold call

A CXTransaction wraps those actions so the system can:

• validate them
• coordinate telephony state
• execute them safely
