在Swift中使用@observable，我希望使用计时器定期刷新ObservedObject。我该怎么做呢？

class MyViewModel: ObservableObject {
    @Published var data: String = ""
}

struct MyView: View {
    @ObservedObject var viewModel = MyViewModel()
    
    var body: some View {
        Text(viewModel.data)
    }
}

struct MyView: View {
    @ObservedObject var viewModel = MyViewModel()
    var timer: Timer?
    
    init() {
        timer = Timer.scheduledTimer(withTimeInterval: 1.0, repeats: true) { _ in
            // 更新ObservedObject对象的属性
            viewModel.data = "Updated data"
        }
    }
    
    var body: some View {
        Text(viewModel.data)
    }
}

struct MyView: View {
    @ObservedObject var viewModel = MyViewModel()
    var timer: Timer?
    
    init() {
        timer = Timer.scheduledTimer(withTimeInterval: 1.0, repeats: true) { _ in
            // 更新ObservedObject对象的属性
            viewModel.data = "Updated data"
        }
    }
    
    var body: some View {
        Text(viewModel.data)
    }
    
    // 在视图销毁时停止计时器
    func stopTimer() {
        timer?.invalidate()
        timer = nil
    }
    
    // 在视图销毁时调用停止计时器的方法
    deinit {
        stopTimer()
    }
}
