SwiftUI 4.0 introduces a new NavigationStack view.
Let's consider this simple structure.
struct Item: Identifiable, Hashable {
static let sample = [Item(), Item(), Item()]
let id = UUID()
}
When a NavigationLink is nested in another one, the navigation loses its animation and the backtracking takes directly to the root. Did I miss something, or is this a bug?
struct ItemDetailView: View {
let item: Item
var body: some View {
Text(item.id.uuidString)
}
}
struct ItemListView: View {
var body: some View {
List(Item.sample) { item in
NavigationLink(item.id.uuidString, value: item)
}
}
}
struct ExploreView: View {
var body: some View {
List {
Section {
NavigationLink {
ItemListView()
} label: {
Text("Items")
}
}
}
.navigationTitle("Explore")
.navigationDestination(for: Item.self) { item in
ItemDetailView(item: item)
}
}
}
struct ContentView: View {
var body: some View {
NavigationStack {
ExploreView()
}
}
}
Thanks!
Found the solution thanks to @Asperi's comment.
First, create a Hashable enum containing the destinations.
enum Destination: Hashable {
case items
var view: some View {
switch self {
case .items:
return ItemListView()
}
}
var title: LocalizedStringKey {
switch self {
case .items:
return "Items"
}
}
}
Next, use the new NavigationLink initializer.
NavigationLink(Destination.items.title, value: Destination.items)
And finally, add a new .navigationDestination modifier to catch all Destination values.
.navigationDestination(for: Destination.self) { destination in
destination.view
}
