将新项目添加到模型的字符串数组并显示它们时出现问题

Question

我在模型中有一个属性，它最初是空的字符串数组（userReports），它将保存用户的注释。但是当我尝试向其附加值并显示它时，它没有任何更新。我绞尽脑汁地理解数据持久性，所以我不确定我是否以正确的方式处理这件事。

@Model
final class ActiveStash {
    var substanceClass: String
    var substance: String
    var weight: UInt
    var substanceCost: UInt?
    var StashDescription: String?
    var date: Date
    var unit: String
    var dosages: Int?
    var userReports: [String]?

    init(substanceClass: String, substance: String, weight: UInt, substanceCost: UInt? = nil, StashDescription: String? = nil, date: Date, unit: String, dosages: Int? = nil, userReports: [String]? = nil) {
        self.substanceClass = substanceClass
        self.substance = substance
        self.weight = weight
        self.substanceCost = substanceCost
        self.StashDescription = StashDescription
        self.date = date
        self.unit = unit
        self.dosages = dosages
        self.userReports = userReports
    }
}

将用户报告添加到模型的功能

   func addReport() {
        guard !inputReport.isEmpty else {
            return
        }

        var updatedReports = stashed.userReports
        stashed.userReports = updatedReports

        updatedReports.append(inputReport)

        try? modelContext.save()

        dismiss()
    }

我如何尝试在从另一个页面调用函数后显示文本

struct StashLinkView: View {
    @Environment(\.modelContext) var modelContext
    let stashed: ActiveStash
    @State private var viewSelect = "Usage"
    var viewName = ["Usage", "Report"]
    let currencySymbol = Locale.current.currencySymbol ?? ""
    @State private var isSheetShown = false
    
    var body: some View {
        VStack {
           /// other code
        }

   // not sure im im doing this block  correctly

        VStack {
            if let userReports = stashed.userReports, !userReports.isEmpty {
                ForEach(userReports, id: \.self) { report in
                    VStack {
                        Text(report) 
                    }
                }
            } else {
                Text("No Notes")
            }
        }

Answer 1

func addReport() { 守卫！inputReport.isEmpty else { 返回 }

    stashed.userReports.append(inputReport)

    try? modelContext.save()

    dismiss()
}
