我正在研究一种方法来监听对象的变化。下面的代码片段是我正在进行的解决方案。
在这里，每当isSelected bool更改时，我必须更新UI。

class OfferDetail: ObservableObject {
    @Published var items: [OfferItem]
    private var anyCancellables = Set<AnyCancellable>()

    init(deliveryAddress: String, deliveryDate: String, offerItems: [OfferItem]) {
        self.items = offerItems
        for item in items {
            item.$isSelected
            .sink(receiveValue: { _ in
                print("OfferDetail Update 1")
                self.objectWillChange.send()
            })
            .store(in: &anyCancellables)
        }
    }
}

class OfferItem: Identifiable, ObservableObject {
    @Published var isSelected: Bool = false
    let uuid = UUID()
    
    init() {
        print(uuid)
    }
    
}

class ViewModel: ObservableObject {
    @Published var offer: OfferDetail?
    private var anyCancellables = Set<AnyCancellable>()

    init() {
        offer = OfferDetail(deliveryAddress: "", deliveryDate: "", offerItems: [OfferItem(), OfferItem()])
        offer?.$items.sink { items in
            print("ViewModel Update 2")
            
            for item in items {
                print(item.uuid, item.isSelected)
            }

        }.store(in: &anyCancellables)
    }
    
}

let viewModel = ViewModel()
viewModel.offer?.items.first?.isSelected = true

这是监听数组中对象变化的正确方法吗？
