    # 피어세션 iOS04 # 영균님 - OpenList 동시 편집 기능 구경 - CRDT 메세지의 크기가 너무 큰 문제 한번 보낼 때마다 200~300바이트를 보낸다. - PagingViewController이 컨테이너 뷰컨트롤러인데 페이징 화면을 구현하는데 쉽다. - 웹소켓을 뷰컨에서 가져가는 이유? - 웹소켓을 네트워크 영역까지 요청해서 뷰로 응답을 받아오는 과정이 복잡해서 어느 정도 유연한 아키텍쳐를 가져가는 것이 중요하 # 준복님 - RIBs - 당일날 에러 발생 일관적인 에러가 아니라 누구는 되고 누구는 안되는 에러 - http -> https 로 해결 s 차이가 너무 크다 ~ - 맵, 팔로잉, 팔로우, 글쓰기, 댓글쓰기 등등등 - 클린 아키텍쳐란 무엇일까 ? - 정말 교체할 일이 있을까 ? # 성민님 - APNs, FCM - 왜 안될까... - WebSocket 실시간 채팅 - 애플 로그인 + 자동 로그인 - 토큰을 언제 만료시킬까 - MVVM + CleanArchitecture의 UseCase를 어느 단위로? # 클린 아키텍처 이녀석 **준복** - 솔리드 원칙을 지키면 클린아키텍처가 되는건가? - 이거 좋은것인가? 뭐가 좋은 거지 - 프로토콜이 변경되면 어차피 코드 수정을 해야하는데 유지보수 측면에서 좋은 건가? **영균** |usecase|repository|storage| |:---:|:---:|:---:| |체크리스트을 동시편집 입력한다|동시편집 Repository|서버 스토리지| |||로컬 스토리지| 레포지토리에서 스토리지에 접근을 컨트롤할 수 있어서 편리한 것 같음. **성민님** 레포지토리랑 유즈 케이스가 없다. 그래도 불편함이 없고 편리함. 뷰모델로도 충분하다. 그런데 뷰 개수가 많지 않아서 그런거 같은데 복잡한 앱이 되면 테스트도 해야하고 그러니까 유즈케이스랑 레포지토리가 있으면 좋겠다는 생각이 든다. **태현님** 클린아키텍처를 쓰는 이유? 템플릿처럼 쓰고싶어서 처음에 도입했다. 아키텍처를 고를 때 서비스에 맞는 것을 고르고 싶었는데 맞는 아키텍처를 찾는 것이 어려웠다. 그래도 일관된 코드를 작성하고 싶어서 도입한 면이 있다. 그차이점은 뷰모델을 다르게 가져갔는데 뷰 모델도 일관된 코드 작성을 하기 위해서 뷰 모델을 단방향 흐름을 가져가기 위해 고민했다.(리액터킷을 참고해서 구현했다.) 단발성 비동기 응답에는 스위프트 동시성을 가져갔는데 스위프트 동시성을 뷰모델의 퍼블리셔로 바꾸기 위해 고민함. 지금은 뷰 모델은 액션과 사이드 이펙트를 수행하여 상태를 변환하고, 비즈니스 로직은 유즈 케이스가 처리함. 좋은 점은 데이터를 가져오는 레포지토리만 변경해주면 되니까 좋은듯하다.
