Navigation bar issues

Forums > SwiftUI

Following the SwiftUI tutorial: Building a complete project tutorial and running into two issues.

The first is during navigation between Orders to Place Order results in the navigation bar title jumping when going from inline -> largeTitle. However, it is only in this view because the same navigation setup is used in ContentView but the transition is smooth.

The second is after deleting items from the list in Order view and adding more items, the Edit button no longer results in the delete mode being activated for each item. The Edit button does change to Done but that is it.

struct OrderView: View {
    @EnvironmentObject var order: Order

    var body: some View {
        NavigationStack {

            List {
                Section {
                    ForEach(order.items) { item in
                        HStack {
                            Text(item.name)
                            Spacer()
                            Text("$\(item.price)")
                        }
                    }
                    .onDelete(perform: deleteItems)
                }

                Section {
                    NavigationLink("Place Order") {
                        CheckoutView()
                    }
                }
                .disabled(order.items.isEmpty)
            }
            .navigationTitle("Order")
            .toolbar {
                EditButton()
            }

        }
    }

    func deleteItems(at offsets: IndexSet) {
        order.items.remove(atOffsets: offsets)
    }
}

struct OrderView_Previews: PreviewProvider {
    static var previews: some View {
        NavigationStack {
            OrderView()
                .environmentObject(Order())
        }
    }
}
