multipeer-connectivity

To discover and connect nearby Apple devices for local multiplayer, instantiate an MCPeerID, start advertising with MCNearbyServiceAdvertiser, and browse with MCNearbyServiceBrowser to establish an MCSession connection.

Peer-to-peer data transfer for nearby devices enables direct device-to-device collaboration without internet access. You need it when building local multiplayer games or collaborative apps that must share data, files, or streams locally.

Yes, you can use Bonjour service advertising to establish an MCSession without internet. MultipeerConnectivity relies on Bonjour to discover nearby peers and set up device-to-device connections for local collaboration.

To handle invitations and manage session state for nearby peer connections, implement the delegate methods for MCNearbyServiceBrowser invitations and track MCSession state transitions to manage connected, connecting, and disconnected peers.

Yes, peer-to-peer data transfer works for transferring files and streams between peers. Once an MCSession is established, you can send data, files, and byte streams directly between connected nearby devices.

A limitation of using MultipeerConnectivity for local device discovery is that it requires nearby Apple devices and does not function over the internet, restricting its use to local, device-to-device collaboration and data transfer scenarios.
