I was working through the first part of this task, "Building a list we can delete from", and after creating the sample list with the ability to add and delete "Test" items, I expected that when swiping to delete an item that always the last one would be deleted, rather than the one I was swiping (as showing in the video). However I found I was able to swipe and delete specific rows correctly, without having to add an id property to the ExpenseItem class. This is my code:

struct ExpenseItem {

    let name: String

    let type: String

    let amount: Int
}

class Expenses: ObservableObject {

    @Published var items = [ExpenseItem]()

}

struct ContentView: View {

    @ObservedObject var expenses = Expenses()

    var body: some View {

        NavigationView {

            List {

                ForEach(expenses.items, id: \.name) { item in

                    Text(item.name)
                }
                .onDelete(perform: { indexSet in

                    self.removeItems(at: indexSet)
                })
            }
            .listStyle(PlainListStyle())
            .navigationBarTitle("iExpense")
            .navigationBarItems(trailing:

                Button(action: {

                    let expense = ExpenseItem(name: "Test", type: "Test Type", amount: 1)
                    self.expenses.items.append(expense)

                }, label: {

                    Image(systemName: "plus")
                })
            )
        }
    }

    func removeItems(at offsets: IndexSet) {

        self.expenses.items.remove(atOffsets: offsets)
    }
}

Has anything changed in SwiftUI since this was published so that it no longer necessary to add an id property to a class used in a list like this, or to conform to the Identifiable protocol? Or have I overlooked something in my code?

For reference I'm using XCode 12.5 and running on an iOS 14.5 simulator
