Answer 1

func session(_ session: MCSession, peer peerID: MCPeerID, didChange state: MCSessionState) {
    switch state {
    case .connected:
        print("connected", peerId)
        lbl.text = UIDevice.current.name
    case .connecting:
        print("connecting")
    case .notConnected:
        print("not Connected")
    default: break
    }
}

Try above code to show device name which is connected.
