把想法，做成好用的软件。

import SwiftUI

struct OrderView: View {
    @StateObject var store = OrderStore()

    var body: some View {
        List(store.orders) { order in
            OrderRow(order)
                .badge(order.items.count)
        }
        .navigationTitle("今日订单")
        .refreshable { await store.sync() }
    }
}
