将 Xcode 12.4 升级到 13.3.1 后数据未正确保存

Question

我正在开发一个使用 Xcode 12.4 的应用程序，它保存正确。现在我有了一台新电脑并升级到 Xcode 13.3.1 当我输入“123456”时它保存为“12345”如果我输入“1234567”然后在保存之前删除“7”它保存为“ 12345”。如果我输入“12345”或“1234567”然后点击保存，它就可以正常工作。

我不知道代码的哪一部分可能导致此问题或需要包含哪些其他信息。

我认为这是一个 Xcode 问题，而不是我的代码的问题。

我在保存按钮上有一个打印语句，但当时的代码是错误的。 “123456”打印为“12345”

struct AddTripView: View {
    @Environment(\.presentationMode) var presentationMode
    @StateObject private var addTripViewModel: AddTripViewModel
    
    init(repo: RepositoryProtocol) {
        _addTripViewModel = StateObject<AddTripViewModel>.init(wrappedValue: AddTripViewModel(repo: repo))
    }
    
    var body: some View {
        Form {
            HStack {
                Text("BOL:").fontWeight(.bold)
                TextField("BOL", text: $addTripViewModel.bol).keyboardType(.numberPad)
            }
        }
        .toolbar {

                    print("AddView \(addTripViewModel.bol)")
                    presentationMode.wrappedValue.dismiss()
