This article provides instructions on explicitly configuring your Ditto instance to listen for connections on a specific port and to connect to remote instances using a host (IP) and port.
Although Ditto automatically attempts to connect to other instances on the Local Area Network (LAN), Bluetooth Low Energy (LE), and Apple Wireless Direct Link (AWDL), supplying a DittoTransportConfig does not enable this feature by default.Rather, you manually enable peer-to-peer connections using EnableAllPeerToPeer(). (See Enabling and Disabling Transports)

​
Enabling and Disabling Transports

// Create a new DittoTransportConfig()
var config = DittoTransportConfig()

//Enable all peer to peer transports
config.enableAllPeerToPeer()

//Or enable/disable each transport separately
//BluetoothLe
config.peerToPeer.bluetoothLE.isEnabled = true
//Local Area Network
config.peerToPeer.lan.isEnabled = true
//Awdl
config.peerToPeer.awdl.isEnabled = true

ditto.transportConfig = config

do {
  try ditto.startSync()
} catch (let err) {
  print(err.localizedDescription)
}
