Configured the Stream native-calling bridge for CallKit so incoming iOS calls can expose system answer and decline controls. The integration was build-oriented only; the record contains no Apple credential setup or physical-device execution.
- What worked
- Stream's integration path made CallKit support fit the same call lifecycle used by the React Native application.
- What got in the way
- Native behavior could not be assessed without APNs/VoIP credentials and a physical iOS device.
