类型“工作”没有成员“下标”

如何解决类型“工作”没有成员“下标”

好的，我正在尝试在另一个视图中获取列表元素以查看更多详细信息并与之交互。现在，这是代码片段：（注意，这是在导航视图中，语法是正确的）

//below is listed before the body
@Observedobject var jobviewmodel: Jobviewmodel

//The rest is a snippet of the code in question
List{
                    ForEach(jobviewmodel.jobs){ job in
                        let jobDate = ParserDate(date: job.date)
                        if job.completed == false && jobDate == comparisonDate{
                            let jobTime = ParserTime(time: job.date)
                            
                            NavigationLink(destination: dummy(job: job))
                                {
                                vstack(alignment: .leading){
                                    HStack{
                                        Text("Boat Name")
                                            Spacer()
                                                .frame(width: 50,height: 50)
                                        Text(job.boatName)
                                    }
                                //Text(job.boatID)
                        
                                    HStack{
                                        Text("Job Time")
                                            Spacer()
                                                .frame(width: 50,height: 50)
                                        Text(jobTime)
                                    }
                                    HStack{
                                        Text("Job Type")
                                            Spacer()
                                                .frame(width: 50,height: 50)
                                        Text(job.job)
                                    }
                                    HStack{
                                        Text("Owner's Name")
                                        Spacer()
                                            .frame(width: 50,height: 50)
                                        Text(job.ownerName)
                                        //Text(job.time)
                                    }
                                }
                            }
                        }
                    
                    }
                    
                }

这是目前的虚拟视图：

import SwiftUI

struct dummy: View {
    let job: Job
    
    
    var body: some View {
        Text("Placeholder for job details,will not exists in production,please delete")
        vstack(alignment: .leading){
            HStack{
                Text("Boat Name")
                    Spacer()
                        .frame(width: 50,height: 50)
                Text(job.boatName)
            }
        Text(job.boatID)

            /*HStack{
                Text("Job Time")
                    Spacer()
                        .frame(width: 50,height: 50)
                Text(jobTime)
            }*/
            HStack{
                Text("Job Type")
                    Spacer()
                        .frame(width: 50,height: 50)
                Text(job.job)
            }
            HStack{
                Text("Owner's Name")
                Spacer()
                    .frame(width: 50,height: 50)
                Text(job.ownerName)
                //Text(job.time)
            }
        }
        
        
        
        
    }
}

struct dummy_Previews: PreviewProvider {
    static var previews: some View {
        dummy(job: Job[0])
    }
}

在“dummy(job: Job[0])”行上，我收到此错误： 类型“作业”没有成员“下标”。我不知道我哪里出错了。任何帮助表示赞赏。
