swiftui @State值取决于@ObservedObject ViewModel初始化错误

我很简单viewModel：

final class EmployeeListViewModel: ObservableObject {
 @Published var list = [Employee]()
 init() {
  // some request
  self.list = [Employee, Employee]
 }
}

并有一个view：

struct EmployeeView: View {
 @ObservedObject var viewModel = EmployeeListViewModel()
 @State private var showContents: [Bool] = Array(repeating: false, count: viewModel.list.count)// <- error throws here
 var body: some View {
        GeometryReader { fullView in
            ScrollView {
                VStack(spacing: 40) {
                  ForEach(self.viewModel.list) { employee in
                     Text(employee.firstName).foregroundColor(.black)
                  }
                }
            }
        }
 }
}

错误文字：

无法在属性初始化程序中使用实例成员“ viewModel”；属性初始化程序在“自我”可用之前运行

我尝试用更改它init：

struct EmployeeView: View {
 @ObservedObject var viewModel = EmployeeListViewModel()
 @State private var showContents: [Bool]

 init() {
        _showContents = State(initialValue: Array(repeating: false, count: viewModel.list.count)) // <- error
    }

 var body: some View {
        GeometryReader { fullView in
            ScrollView {
                VStack(spacing: 40) {
                  ForEach(self.viewModel.list) { employee in
                     Text(employee.firstName).foregroundColor(.black)
                  }
                }
            }
        }
 }
}

但这也会引发错误：

在初始化所有存储的属性之前使用“自我”

这将引发对我叫viewModel上init()

怎么解决呢？@State我用于卡片视图。在那里我简化了视图，以便于理解。
