🗂 SKMessagePort

SKMessagePort는 iOS 또는 macOS 플렛폼에서 로컬 장비 상에서 다중 쓰레드 및 프로세스들 간에 임의의 데이터를 전달하는 통신 채널을 제공합니다. 즉, 서로 다른 애플리케이션, 또는 애플리케이션과 프레임워크, 또는 서로 다른 프레임워크 사이의 통신을 할 수 있는 기능을 제공합니다.

Example Source

SKMessagePort 예제 소스코드는 아래와 같습니다.

// https://developer.apple.com/documentation/corefoundation/cfmessageportcallback
let callback: CFMessagePortCallBack = { local, msgid, data, info -> Unmanaged<CFData>? in

    let pointee = info!.assumingMemoryBound(to: [ViewController].self).pointee

    /* here is processing data */

    return nil
}

// https://developer.apple.com/documentation/corefoundation/cfmessageportinvalidationcallback
let callout: CFMessagePortInvalidationCallBack = { local, info in

    let pointee = info!.assumingMemoryBound(to: ViewController.self).pointee

    /* here is processing invaild local port */
}

var pointee = self

let local = SKMessagePort(localPortName: "com.systemkit.port",
                          info: UnsafeMutablePointer(mutating: &pointee), callback, callout)

// 다른 프로세스 또는 쓰레드로부터 데이터를 수신할 수 있도록 Listen 상태를 수행합니다.
local.listen(runLoop: .main)

let remote = SKMessagePort(remotePortName: "com.systemkit.port", callout)

let error = remote.send(messageID: 12345, message: Data(), sendTimeout: 1, recvTimeout: 1)
print(error)

// 생성 된 CFMessagePort 소멸 작업을 수행합니다.
local.invalidate()
remote.invalidate()
