Does code at 04:41 compile?

The code for @State doesn't seem to work.

struct DonutListView: View {
    var donutList: DonutList
    @State private var donutToAdd: Donut?

    var body: some View {
        List(donutList.donuts) { DonutView(donut: $0) }
        Button("Add Donut") { donutToAdd = Donut() }
            .sheet(item: $donutToAdd) { // <-- would need a "donut in"
                TextField("Name", text: $donutToAdd.name) // <-- donutToAdd is optional and I'm not sure how it would be unwrapped
                Button("Save") {
                    donutList.donuts.append(donutToAdd)
                    donutToAdd = nil
                }
                Button("Cancel") { donutToAdd = nil }
            }
    }
}

Does anyone have a fix for this?

Thanks, Dan!
