시간표 화면 nonModal 바텀시트 대응을 위해, addChild 방식 바텀시트를 구현했습니다.
기존 present 방식 바텀시트 (BottomSheetViewController, BottomSheetViewControllerB)와 주변상점 정렬에서 사용하는 시스템 시트를 없애고, addChild 방식 KoinBottomSheet로 통일했습니다.
1. KoinBottomSheet 추가 (Core/View/UIKit/KoinBottomSheet)
- 콘텐츠(KoinBottomSheetContent)가 너비·최대 높이 맥락을 받아 시트 높이를 정한다(기본 구현은 Auto Layout fitting)
- modal·nonModal, 같은 화면(owner와 modal host)당 활성 시트 1개(교체 시 닫기와 열기 동시 진행)
- 하단은 키보드 위에 붙고, 키보드 뒤 배경으로 iOS 26 키보드 모서리 틈을 덮는다
- 배치 기준은 host 뷰의 safe area·키보드 가이드(내비게이션·탭 바 host 대응)
- pan: 닫기·축소·fullscreen 펼치기 모두 시트 전체 영역(스크롤 뷰 위에서는 방향과 스크롤 위치로 소유자 결정). 놓을 때 예측 높이로 목적지 결정. 키보드가 열려 있으면 아래 pan은 키보드만 닫는다
- 위치 이동은 단일 컨테이너 transform, 표시·닫기·높이 전환은 공통 spring(pan 속도 이어받기)
- ShopSortOptionSheetViewController를 ShopSortOptionSheetView(UIView)로 변경
- 시스템 시트 실측값 재현: 높이 233(+하단 safe area), dim 0.2, 반경 32
- grabber는 그리지 않고, 아래로 끌어 닫기는 시트 pan이 맡는다
- 옵션 선택은 시트를 닫은 뒤 콜백 실행 (기존 순서 유지)
This pull request adds a UIKit bottom-sheet framework with configurable presentation, content-based height measurement, pan gestures, keyboard handling, and dismissal. It replaces legacy sheet controllers and migrates existing sheet content and presentation call sites to the new framework.
Adds content, delegate, and configuration contracts and the presentBottomSheet and dismissBottomSheet helpers. Removes the legacy sheet controllers and registers the new implementation and migrated views in the Xcode project.
Controller presentation, layout, and height Koin/Core/View/UIKit/KoinBottomSheet/KoinBottomSheetController.swift, Koin/Core/View/UIKit/KoinBottomSheet/KoinBottomSheetController+{Layout,Height,Animation}.swift
Adds controller lifecycle and presentation, content attachment, host constraints, height measurement, and presentation animations.
Pan, keyboard, and dismissal behavior Koin/Core/View/UIKit/KoinBottomSheet/KoinBottomSheetController+{Pan,Keyboard,Dismissal}.swift
Adds pan gestures, keyboard-driven layout and dismissal coordination, teardown, and modal navigation-gesture handling.
Bus and CallVan sheet migration Koin/Core/View/UIKit/FilterBottomSheet/FilterBottomSheetView.swift, Koin/Presentation/Bus/BusSearch/*, Koin/Presentation/CallVan/*
Migrates Bus and CallVan sheets to the new presentation API and content protocol. CallVan place selection also adds scroll handling for the custom-place field.
Dining and Home sheet migration Koin/Presentation/Dining/Dining/DiningHostingController.swift, Koin/Presentation/Dining/Dining/Subviews/DiningNotiBottomSheetContentView.swift, Koin/Presentation/Home/Home/*
Migrates notification and banner sheets to the new API. Sheet actions use dismissal completions where described.
Lost-item, Recruit, and Shop sheet migration Koin/Presentation/LostItem/LostItemList/*, Koin/Presentation/Recruit/*, Koin/Presentation/Shop/Shop/*
Migrates Lost-item and Shop sheet content to views and updates their presentation call sites. Recruit filter sheets use presentBottomSheet.

- Around line 110-115: Add owner-window lifecycle handling in
KoinBottomSheetController so teardown() is called when
owner.viewIfLoaded?.window becomes nil, including when the sheet remains visible
on its navigation or tab-bar host. Do not rely solely on the sheet’s
viewDidDisappear to detect the owner leaving the window.

Guard both deferred pushes against a detached owner.
248-264: Minor · Functional Correctness · Quick win
Guard both deferred pushes against a detached owner.
When LostItemListViewController leaves the window but remains in a navigation stack, teardown() still invokes the pending dismissal completion. The current guard let self succeeds, so either closure can push PostLostItemViewController onto the inactive navigation stack.
Suggested fix
- guard let self else { return }+ guard let self, viewIfLoaded?.window != nil else { return }
...
- guard let self else { return }+ guard let self, viewIfLoaded?.window != nil else { return }
Apply the guards at LostItemListViewController.swift:250 and :259. Do not add the guard to shared teardown(), because other dismissal completions persist data or apply filters and must still run.

@Koin/Presentation/LostItem/LostItemList/LostItemListViewController.swift around
lines 248 - 264:
Both deferred dismissal completions can push PostLostItemViewController after
LostItemListViewController is detached from the window. In onFoundButtonTapped
and onLostButtonTapped, check that the controller is still attached to a window
before each push, alongside the existing weak-self check; leave shared teardown
behavior unchanged.
Guard the notification navigation completion with the owner window.
270-270: Minor · Functional Correctness · Quick win
Guard the notification navigation completion with the owner window.
If DiningHostingController leaves its window during sheet dismissal, dismiss(completion:) can still invoke navigateToNoti. The bound navigation controller can then push NotiViewController from the detached owner. Apply the guard only to this callback so other dismissal completions still run.

at line 270:
Guard only the onNotiButtonTapped callback in DiningHostingController: capture
self weakly and call navigateToNoti only if self still exists and its loaded
view remains attached to a window. Leave other dismissal completions unchanged.
