SwiftUI中带.searchable的二级视图跳转三级视图时界面异常无响应

我用SwiftUI的NavigationStack搭建了三级导航结构。在二级视图中添加了.searchable修饰符后，当搜索栏处于收起（等待输入）状态时跳转到三级视图，会出现三级视图布局越界、CPU占用率拉满至100%、应用完全无响应的情况。移除.searchable修饰符后，该异常完全消失，希望找到问题根源。

一级视图代码 #

struct MainDatabaseView: View {
    @EnvironmentObject var routeManager: RouteManager

    var body: some View {
            Form {
                NavigationLink(value: Route.mainDatabasePilot) {
                    Button {
                        routeManager.databaseRoute.append(Route.mainDatabasePilot)
                    } label: {
                        DatabaseLabelLineView(icon: "person.2", primaryText: "Pilots", secondaryText: "Manage pilot profiles, remarks, and images. Use them for auto-complete.")
                    }
                }
              
            }
            .navigationDestination(for: Route.self, destination: { $0 })
            .navigationTitle("Database")
        
    }
}

二级带.searchable修饰符的视图代码 #

struct MainTabPilotDatabaseView: View {
    @EnvironmentObject var pilotVM: PilotVM
    @EnvironmentObject var routeManager: RouteManager

    var body: some View {
        ZStack {
            listView()
            if pilotVM.pilotCollection.isEmpty {
                EmptyDataView(primaryText: "No Pilots Yet", secondaryText: "You can add pilots into database here. When importing existing logbooks, pilots will be automatically migrated", image: .emptyDatabase)
            }
        }
    }

    @ViewBuilder
    func listView() -> some View {
        List {
            ForEach(pilotVM.filteredPilots, id: \.id) { pilot in

                NavigationLink(value: Route.pilot(pilot: pilot)) {
                    PilotCell(pilot: pilot, isInDetailView: false) {}
                        .contentShape(Rectangle())
                        .swipeActions(edge: .trailing) { delete(for: pilot) }
                        .swipeActions(edge: .leading) { markFavorite(for: pilot) }
                }
            }
        }
        .searchable(text: $pilotVM.searchText, placement: .navigationBarDrawer(displayMode: .always), prompt: "Name, Base, Airline, Remarks")
        .overlay {
            if pilotVM.filteredPilots.isEmpty && !pilotVM.pilotCollection.isEmpty && !pilotVM.searchText.isEmpty {
                if #available(iOS 17.0, *) {
                    ContentUnavailableView.search(text: pilotVM.searchText)
                }
            }
        }
        .onAppear { pilotVM.fetchPilots() }
        .onDisappear { pilotVM.searchText = "" }
        .autocorrectionDisabled()
        .navigationTitle("Pilot Database")
        .toolbar {
            ToolbarItem(placement: .topBarTrailing) { addPilot() }
        }
    }
}

三级视图为简单的Form结构，我尝试注释掉三级和二级视图的内容后，确认异常仅在.searchable修饰符存在时触发。

堆栈调用信息 #

• 截图1：显示大量重复的SwiftUI布局相关调用，包含UIView.layoutSubviews()、SwiftUI.ViewRendererHost.updateView()等循环执行的方法
• 截图2：调用栈集中在UISearchBar的布局逻辑链上，呈现出明显的循环调用迹象
