ios - 无法将类型 'Published.Publisher' 的值转换为预期的参数类型 'Binding'

Question

尝试编译以下代码时:

class LoginViewModel: ObservableObject, Identifiable {
    @Published var mailAdress: String = ""
    @Published var password: String = ""
    @Published var showRegister = false
    @Published var showPasswordReset = false

    private let applicationStore: ApplicationStore

    init(applicationStore: ApplicationStore) {
        self.applicationStore = applicationStore
    }

    var passwordResetView: some View {
        PasswordResetView(isPresented: $showPasswordReset) // This is where the error happens
    }
}

PasswordResetView 如下所示:

struct PasswordResetView: View {
    @Binding var isPresented: Bool
    @State var mailAddress: String = ""
    
    var body: some View {
            EmptyView()
        }
    }
}

我收到错误编译错误

Cannot convert value of type 'Published<Bool>.Publisher' to expected argument type 'Binding<Bool>'

如果我从 LoginViewModel 类之外使用发布的变量，它就可以正常工作:

struct LoginView: View {
    @ObservedObject var viewModel: LoginViewModel

    init(viewModel: LoginViewModel) {
      self.viewModel = viewModel
    }
    
    var body: some View {
            PasswordResetView(isPresented: self.$viewModel.showPasswordReset)
    }
}

有什么建议我在这里做错了吗？我有没有机会从所属类内部将发布的变量作为绑定(bind)传递？
谢谢!

当有一个非常直接的解决方案时，不知道为什么这里提出的解决方案如此复杂。
在 similar Reddit question 上找到了这个答案:

The problem is that you are accessing the projected value of an @Published (which is a Publisher) when you should instead be accessing the projected value of an @ObservedObject (which is a Binding), that is: you have globalSettings.$tutorialView where you should have $globalSettings.tutorialView.
