SwiftUI NavigationSplitView — вложенный список не анимируется ⇐ IOS

[Anonymous]

Я столкнулся с ошибкой SwiftUI NavigationSplitView в своем приложении, с которой я был бы признателен за помощь. Я потратил довольно много времени, пытаясь найти решение этой проблемы. У меня есть основной список, который имеет либо Location, либо LocationGroup. При выборе местоположения отображается подробное представление. При выборе группы местоположений отображается последующий список местоположений (из группы). При нажатии на любое из этих Location NavigationStack не анимирует (перемещает представление), а при ответном нажатии на него происходит переход к основному выбору.
I Буду очень признателен за помощь с этой ошибкой в ​​моем коде, спасибо!
Вот GIF-изображение возникающей ошибки:



Я создал следующий пример кода, воспроизводящий проблему:
ContentView.swift
public enum LocationSplitViewNavigationItem: Identifiable, Hashable {
case location(Location)
case locationGroup(LocationGroup)

public var id: UUID? {
switch self {
case .location(let location):
return location.id
case .locationGroup(let locationGroup):
return locationGroup.id
}
}
}

struct ContentView: View {

@State private var columnVisibility = NavigationSplitViewVisibility.doubleColumn
@State private var selectedNavigationItem: LocationSplitViewNavigationItem?

var body: some View {
NavigationSplitView(columnVisibility: $columnVisibility) {
LocationListView(selectedItem: $selectedNavigationItem, locationData: LocationSampleData(locations: LocationSampleData.sampleLocations, locationGroups: LocationSampleData.sampleLocationGroups))
} detail: {
if let selectedLocation = selectedNavigationItem {
switch selectedLocation {
case .location(let location):
LocationDetailView(selectedLocation: location)
case .locationGroup(let locationGroup):
LocationListView(selectedItem: $selectedNavigationItem, locationData: LocationSampleData(locations: locationGroup.locations))
}
}
}
.navigationSplitViewStyle(.balanced)
}
}

LocationListView.swift
struct LocationListView: View {

@Binding public var selectedItem: LocationSplitViewNavigationItem?
var locationData: LocationSampleData

var body: some View {
List(selection: $selectedItem) {
if let locations = locationData.locations {
ForEach(locations) { location in
NavigationLink(value: LocationSplitViewNavigationItem.location(location)) {
Text(location.name)
.bold()
}
}
}

if let locationGroups = locationData.locationGroups {
ForEach(locationGroups) { locationGroup in
NavigationLink(value: LocationSplitViewNavigationItem.locationGroup(locationGroup)) {
Text(locationGroup.name)
.bold()
.foregroundStyle(.red)
}
}
}
}
.navigationTitle("Saturday Spots")
.navigationBarTitleDisplayMode(.large)
}
}

LocationDetailView.swift
struct LocationDetailView: View {
var selectedLocation: Location
var body: some View {
Text(selectedLocation.name)
.font(.largeTitle)
.bold()
.foregroundStyle(LinearGradient(
colors: [.teal, .indigo],
startPoint: .top,
endPoint: .bottom
))
.toolbarBackground(
Color.orange,
for: .navigationBar
)
.toolbarBackground(.visible, for: .navigationBar)
}
}

Location.swift
import CoreLocation

struct LocationSampleData {
var locations: [Location]?
var locationGroups: [LocationGroup]?

static let sampleLocations: [Location]? = Location.sample
static let sampleLocationGroups: [LocationGroup]? = [LocationGroup.sample]
}

public struct Location: Hashable, Identifiable {
var name: String
var coordinates: CLLocationCoordinate2D
var photo: String
public var id = UUID()

static public let sample: [Location] = [
Location(name: "Best Bagel & Coffee", coordinates: CLLocationCoordinate2D(latitude: 123, longitude: 121), photo: "asdf"),
Location(name: "Absolute Bagels", coordinates: CLLocationCoordinate2D(latitude: 123, longitude: 121), photo: "asdf"),
Location(name: "Tompkins Square Bagels", coordinates: CLLocationCoordinate2D(latitude: 123, longitude: 121), photo: "asdf"),
Location(name: "Zabar's", coordinates: CLLocationCoordinate2D(latitude: 123, longitude: 121), photo: "asdf"),
]

static public let oneSample = Location(name: "Absolute Bagels", coordinates: CLLocationCoordinate2D(latitude: 123, longitude: 121), photo: "asdf")
}

public struct LocationGroup: Identifiable, Hashable {
var name: String
var locations: [Location]
public var id = UUID()

static public let sample: LocationGroup = LocationGroup(name: "Bowling", locations: [
Location(name: "Frames Bowling Lounge", coordinates: CLLocationCoordinate2D(latitude: 123, longitude: 121), photo: "asdf"),
Location(name: "Bowlero Chelsea Piers", coordinates: CLLocationCoordinate2D(latitude: 123, longitude: 121), photo: "asdf")
])
}

extension CLLocationCoordinate2D: Hashable {
public static func == (lhs: Self, rhs: Self) -> Bool {
return lhs.latitude == rhs.latitude && lhs.longitude == rhs.longitude
}

public func hash(into hasher: inout Hasher) {
hasher.combine(latitude)
hasher.combine(longitude)
}
}
