Discussion

important:

You can call this method from synchronous code using a completion handler, as shown on this page, or you can call it as an asynchronous method that has the following declaration:

func nearbyConnectionData(forPeer peerID: MCPeerID) async throws -> Data

For information about concurrency and asynchronous code in Swift, see Calling Objective-C APIs Asynchronously.

This method provides connection data that is required when adding a specific nearby peer to a session if you are using your own service discovery code instead of an MCNearbyServiceBrowser or MCBrowserViewController object. For more information, see the Managing Peers Manually section in the overview of the MCSession class reference.
