A native iOS receiver so an iPhone can act as the second receiver, speaking the existing signaling + RTP protocol (no C++ changes) and mirroring the Android receiver (Phase 8) source-to-source. - RTP core (header/packet, jitter buffer, H.264 depacketizer) ported from the Android receiver - BSD-socket signaling server (dual-stack, most-recent-peer, never-throwing sends) + NSBonjourServices - VideoToolbox H.264 decode (in-band SPS/PPS, real-time, rebuilds on size change) -> AVSampleBufferDisplayLayer - PLI keyframe recovery (500 ms) + pendingOffer for late surface attach - XcodeGen project + bootstrap.sh; XCTest port of the Android suite + new coverage - .gitignore for generated artifacts; CHANGELOG; PHASES + MEMORY updated Status: authored; on-device validation pending a Mac + Xcode 26 + iPhone 16.
