The OSCKit package provides the classes needed for your apps to communicate among computers, sound synthesizers, and other multimedia devices via OSC over an IP network.
Use the OSCKit package to create client or server objects. In its simplest form a client can send a packet, either a Message or Bundle to a server. A server, when listening, can receive these packets and action upon them. Depending on a client or server using either UDP or TCP as a transport, there are varying levels of functionality and delegate methods for you to take advantage of.
OSCKit implements all required argument types as specified in OSC 1.1.
An example project can be found in OSCKitDemo.
OSCKit is licensed under the GNU Affero General Public License, version 3. If you require a commercial license for an application that you would not like to trigger AGPLv3 obligations (e.g. open sourcing your application), please get in touch. The probability of obtaining a commercial license for free is high.

Add the package dependency to your Xcode project using the following repository URL:
https://github.com/SammySmallman/OSCKit
Add the package dependency to your Package.swift and depend on "OSCKit" in the necessary targets:
dependencies: [
.package(url: "https://github.com/SammySmallman/OSCKit", .upToNextMajor(from: "4.0.0"))
]- Enable Incoming Connections (Required for OSCTcpClient, OSCTcpServer, OSCUdpPeer & OSCUdpServer)
- Enable Outgoing Connections (Required for OSCTcpClient, OSCTcpServer, OSCUdpPeer & OSCUdpClient)

func client(_ client: OSCTcpClient,
didConnectTo host: String,
port: UInt16) {
print("Client did connect to \(host):\(port)")
}
func client(_ client: OSCTcpClient,
didDisconnectWith error: Error?) {
if let error = error {
print("Client did disconnect with error: \(error.localizedDescription)")
} else {
print("Client did disconnect")

print("Client did receive packet")
}
func client(_ client: OSCTcpClient,
didReadData data: Data,
with error: Error) {
print("Client did read data with error: \(error.localizedDescription)"
}Create an OSCPacket e.g. An OSC message:
do {
let message = try OSCMessage(with: "/osc/kit", arguments: [1,
3.142,
"hello world!"])
} catch {
print("Unable to create OSCMessage: \(error.localizedDescription)")
}Send the packet
client.send(.message(message))TCP Server

print("Server did stop listening with error: \(error.localizedDescription)")
} else {
print("Server did stop listening")
}
}
func server(_ server: OSCTcpServer,
didReadData data: Data,

}Start listening for new connections and packets:
do {
try server.startListening()
} catch {
print(error.localizedDescription)
}UDP Client
Import OSCKit into your project
import OSCKitCreate a client
let client = OSCUdpClient(host: "10.101.130.101",

func client(_ client: OSCUdpClient,
didSendPacket packet: OSCPacket,
fromHost host: String?,
port: UInt16?) {
