我在代码的View_Preview部分收到以下编译器错误：“调用中缺少参数'userInfo'的参数”。
Xcode建议如下修复：“（userInfo：[Employee]）"，但此修复程序会出现以下编译器错误：“无法转换类型'[Employee]的值。类型'转换为预期的参数类型'[Employee]'“
下面是我的视图代码：

struct EmployeeView: View {
@EnvironmentObject var pilot: Pilot

let userInfo: [Employee]

var body: some View {
    ZStack {
        List {
            ForEach(userInfo, id: \.age) {line in
                EmployeeCardView(employee: line)
            }
        }
    }
}
}

struct EmployeeView_Previews: PreviewProvider {
static var previews: some View {
    EmployeeView()                //ERROR here 
        .environmentObject(Pilot)
}
}

下面是我的数据模型代码：

struct Employee: Identifiable, Codable {
var id = UUID()
var age: Int
var yearGroup: Int
var category: String

init(age: Int, yearGroup: Int, category: String) {
    self.age = age
    self.yearGroup = yearGroup
    self.category = category
}
}

@MainActor class Pilot: ObservableObject {
@Published var pilot: Employee

init(pilot: Employee) {
    self.pilot = pilot
}
var pilotInfo: [Employee] = [
Employee(age: 35, yearGroup: 1, category: "B717")]
}

我也试过这个：

有没有苹果教程解释View_Previews这方面的逻辑？
