멀티플렉서 연결 - 발견 된 장치를 보는 방법

스위프트 4에서 멀티 페어 연결을 사용하고 있습니다. 프로그램을 실행할 때 발견 된 장치를 보는 방법이 궁금합니다. 조금 도움이되지만 여전히 이해가되지 않습니다. 그것의 모든.멀티플렉서 연결 - 발견 된 장치를 보는 방법

필요한 경우 내 전체 코드, 코드를 수정하시기 바랍니다있다가, 나는 또한 아래의 코드의 맨 아래에있는 확장을 넣어 : 나는이를 넣어 위치를 모른다

방금 확장 기능을 편집했지만 serviceBrowser이 다소 잘못되어이 파일을 NetServiceBrowser으로 바꾸려고합니다. 그래서 내가 그 일을했을 때 NetServiceBrowser에는 회원이 없다. dismiss.
