📝작업 내용

이번 PR에서 작업한 내용을 간략히 설명해주세요(이미지 첨부 가능)

팀원 모집 알림 화면, 팀원 모집 채팅 화면 디자인과 홈화면 알림 화면, 콜밴팟 채팅 화면의 디자인이 동일합니다.
홈화면 알림 화면, 콜밴팟 채팅 화면을 재사용할 수 있는 구조로 변경했습니다.

  1. Core/View 대신, Presentation/Shared 에 두었습니다.

    • Core/View 에 둘 정도로 범용적이지 않다고 판단했습니다.
    • 추후 멀티모듈화 시, 불필요한 의존이 발생하는 것을 방지하고자 합니다.
  2. 도메인 Model과 공용 Model을 분리했습니다.

    • 홈화면 알림 화면에서 사용하는 NotificationHistoryItem을 유지한 채, 공용 Model인 NotificationRowModel을 추가했습니다.
    • 콜밴팟 채팅 화면에서 사용하는 CallVanChat, CallVanChatMessage를 유지한 채, 공용 Model인 ChatListModel, ChatMessageRowModel을 추가했습니다.
    • 팀원 모집 등 다른 기능에서 Shared에 있는 화면을 재사용할 때, 도메인 Model과 공용 Model을 매핑해서 사용하면 됩니다.
  3. 기타

    • 혼동을 방지하기 위해 NotificationItem을 NotificationHistoryItem으로 리네이밍했습니다.

Review Change Stack

📝 Walkthrough

Walkthrough

The PR extracts shared notification and chat UI components, moves chat networking into lost-item services, updates navigation wiring, and renames notification-history models and SwiftData records.

Changes

Notification history and shared notification UI

Layer / File(s) Summary
Notification history contracts and persistence
Common/NotificationHistory/*, Koin/Domain/Model/Home/*, Koin/Data/Repository/DefaultNotificationHistoryRepository.swift, Koin/Domain/Repository/NotificationHistoryRepository.swift, Koin/Domain/UseCase/Home/*, NotificationService/*
Notification history types now use NotificationHistoryRecord and NotificationHistoryItem. The model adds logValue mapping.
Notification list presentation and state
Koin/Presentation/Home/Notification/*, Koin/Presentation/Shared/Notification/*
NotificationListView and NotificationRowModel handle list rendering and events. The view model stores local state, emits selection events, and reports delete and mark-as-read failures with toasts.

Shared chat UI

Layer / File(s) Summary
Reusable chat models and views
Koin/Presentation/Shared/Chat/*
Shared chat models, input handling, list rendering, message cells, image events, and keyboard-aware layout were added.
CallVan chat integration
Koin/Presentation/CallVan/CallVanChat/*
CallVan chat now renders through ChatListView and maps CallVan messages into shared row models.

Lost-item chat stack

Layer / File(s) Summary
Lost-item chat data contracts and networking
Koin/Data/DTOs/Decodable/LostItem/LostItemChat/*, Koin/Data/DTOs/Encodable/LostItem/LostItemChat/*, Koin/Data/Service/LostItemService.swift, Koin/Data/Service/Network/API/LostItemAPI.swift
Chat DTOs, requests, API routes, service methods, HTTP configuration, and JSON encoding now use lost-item-specific types.
Lost-item repositories and use cases
Koin/Data/Repository/DefaultLostItemRepository.swift, Koin/Domain/Repository/LostItemRepository.swift, Koin/Domain/UseCase/LostItem/*, Koin/Domain/UseCase/Chat/*
Chat operations moved to LostItemRepository and LostItemService. Lost-item-specific use cases replace the deleted generic chat use cases.
Lost-item chat presentation
Koin/Domain/Model/LostItem/*, Koin/Presentation/LostItem/LostItemChat/*, Koin/Presentation/LostItem/LostItemChatList/*
Lost-item chat models, controllers, cells, headers, and view models now use dedicated LostItemChat types.

Navigation and project wiring

Layer / File(s) Summary
Chat navigation integration
Koin/Apps/SceneDelegate.swift, Koin/Presentation/Home/*, Koin/Presentation/LostItem/*
Push routes and lost-item flows now construct lost-item chat repositories, use cases, view models, and view controllers.
Xcode project organization
koin.xcodeproj/project.pbxproj
Shared notification and chat sources, renamed lost-item chat files, and new build groups were added. Legacy generic chat references were removed.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to 1326e

This refactor makes notification and chat screens reusable, but the persisted notification model rename may prevent existing users from loading notification history, and failed notification updates can leave the screen out of sync with saved data. The new chat contracts also couple domain code to data-layer types and global user state, so the PR is not merge-ready until these issues are fixed or explicitly accepted.

Isolate NotificationViewModel on MainActor.

ViewModelProtocol and NotificationViewModel have no actor isolation. receive(on: DispatchQueue.main) does not provide Swift concurrency actor isolation. The Task may resume away from the main actor and race with input handlers that access notificationHistoryItems. Mark the view model @MainActor or isolate its state updates with MainActor.run.

Add a SwiftData migration for the renamed model.

The previous release persisted NotificationRecord in the shared app-group store. This release registers only NotificationHistoryRecord, with no VersionedSchema or SchemaMigrationPlan. Existing stores can fail to open, causing loadIssueModelContainer for notification-history operations because try? suppresses the initialization error.

Add a compatible migration or preserve the legacy entity mapping. Test an upgrade from the previous release.

Keep Data DTOs and application state outside the Domain chat contract.

LostItemRepository now exposes DTOs from the Data layer. The post-message use case then constructs a Data request and reads UserDataManager.shared. Define domain request and response models, map them in DefaultLostItemRepository, and inject user identity through a domain dependency.

Keep notification state consistent when persistence fails.

Lines 112, 123, and 145 update local state before the repository operation completes. The error paths only show a toast. Line 139 also ignores a single read-update failure. The controller already updates NotificationListView and reports deletion success. If persistence fails, the current list differs from stored notification history until reload.

Update the list only after successful persistence, or restore and republish the prior state in every failure path.

  • Koin/Presentation/Home/Notification/NotificationViewModel.swift#L95-L152: retain prior state or emit success-confirmed state changes after each repository operation.
