Swift Package for macOS, iOS, and tvOS to send sACN (E1.31) DMX Data over UDP using Network.framework.

You only need to initiate a Connection for a universe and you can start sending DMX Data.

let connection = Connection(universe: 1)
connection.sendDMXData(Data([0, 10, 255, 0, 0, 0, 255]))

If you want to use UDP Unicast instead of Multicast, you can simply specify an endpoint yourself:

let connection = Connection(endpoint: .hostPort(host: "192.168.2.102", .sACN), universe: 2)
connection.sendDMXData(Data([0, 10, 255, 0, 0, 0, 255]))

• Sending DMX Data via UDP Multicast and Unicast on IPv4/IPv6
• sACN Package Priority
• Preview Data
• Depends only on Foundation and Network.framework

For Unicast, you need to specify an IPv6 Endpoint. For Multicast, you need to specify the IP version you want to use:

let connection = Connection(universe: 1, ipVersion: .v6)

After you created a connection, you can set the priority per packet using the Connection.sendDMXData(_:priority:isPreviewData:) method. The default priority is 100.

connection.sendDMXData(data, priority: 200)

After you created a connection, you can choose per packet if it is preview data or not using the Connection.sendDMXData(_:priority:isPreviewData:) method. isPreviewData defaults to false.

connection.sendDMXData(data, isPreviewData: true)

Connection does support customizing the port, component identifier (CID), source name, DispatchQueue, and NWConneciton.Parameter. Look into the Documentation for more information.

public convenience init(
    universe: UInt16,
    ipVersion: IPVersion = .v4,
    port: NWEndpoint.Port = .sACN,
    cid: UUID = .init(),
    sourceName: String = getDeviceName(),
    queue: DispatchQueue? = nil,
    parameters: NWParameters? = nil
)
