SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Enables building local, serverless peer-to-peer streaming between nearby devices by orchestrating per-viewer sessions, persistent identities, and reliable discovery.

Core Features & Use Cases

  • Per-viewer session architecture: maintain an independent MCSession per connected peer to enable selective disconnects and per-device state tracking.
  • Local discovery & connectivity: use MCPeerID, MCNearbyServiceAdvertiser, and MCNearbyServiceBrowser for proximity-based device discovery without internet.
  • Secure-by-default: encryption preferences set to required to protect data in transit.
  • Flexible streaming patterns: suitable for live video, file sharing, and local multiplayer in offline environments.
  • Proximity-based workflows: supports nearby devices joining sessions without a central server.

Quick Start

Start by initializing the streamer, start advertising to nearby peers, and accept invitations to create per-viewer sessions for each connected device.

Frequently Asked Questions about multipeerconnectivity-p2p-streaming

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I stream video to nearby iOS devices without internet using Multipeer Connectivity?▼

Peer-to-peer video streaming without internet uses Multipeer Connectivity to establish local mesh sessions between nearby devices. You initialize a streamer and start advertising via MCNearbyServiceAdvertiser for peers to discover and connect.

Can I manage individual peer connections separately in an MCSession?▼

Yes, per-viewer session architecture maintains an independent MCSession for each connected peer. This enables selective disconnects and per-device state tracking rather than sharing one session across all viewers.

Does Multipeer Connectivity support encryption for local mesh network transfers?▼

Multipeer Connectivity supports encryption preferences set to required, protecting data in transit during local mesh network transfers. This secure-by-default configuration safeguards video streams and file sharing between connected peers.

What is the best way to handle peer discovery for offline multiplayer sessions on iOS?▼

Offline multiplayer sessions use MCPeerID with MCNearbyServiceAdvertiser and MCNearbyServiceBrowser for proximity-based discovery. This allows nearby devices to join sessions without a central server or internet connection.

How do I broadcast a live camera feed to multiple viewers using a local P2P mesh?▼

Local P2P mesh broadcasting streams video from a camera by creating per-viewer MCSession instances for each connected device. Persistent MCPeerID identities maintain stable connections and safe background handling during streaming.
