在 SwiftUI 中从表单中删除分隔线

Question

我有一个在 SwiftUI 中创建的静态表（或 SwiftUI 中的表单），我对每个表的工作方式感到满意，除了分隔两个静态单元格的线之外。见下图。

我尝试了几种方法，但似乎没有任何效果。你可以看到他们在那里被注释掉了。

struct Settings_CheckedView: View {
    
    @Environment(\.managedObjectContext) private var viewContext
    @Environment(\.settings) private var settings
    
    @State private var picker1 = 2
    @State private var picker2 = 2
    
    //Tried this first, doesn't seem to affect it.
    /*init() {
        UITableView.appearance().separatorStyle = .none
    }*/
    
    var body: some View {
        Form {
            Section(header: Text("COMPLETED ITEM BEHAVIOR")) {
                VStack {
                    HStack {
                        Text("Auto-Delete Completed Items")
                        Spacer()
                    }
                    Picker("", selection: $picker1) {
                        Text("Off").tag(0)
                        Text("Immediately").tag(1)
                        Text("Delay").tag(2)
                    }
                    .pickerStyle(SegmentedPickerStyle())
                    .onChange(of: picker1, perform: { value in
                        settings.autoDeleteSegment = Int16(value)
                        viewContext.trySave("Updating auto-delete segment value in Settings", loc: "Settings_CheckedView")
                    })
                }
                VStack {
                    HStack {
                        Text("Delay Time Interval")
                        Spacer()
                    }
                    Picker("", selection: $picker2) {
                        Text("5 mins").tag(0)
                        Text("15 mins").tag(1)
                        Text("1 Hr").tag(2)
                        Text("24 Hrs").tag(3)
                    }
                    .pickerStyle(SegmentedPickerStyle())
                    .onChange(of: picker2, perform: { value in
                        settings.deleteDelaySegment = Int16(value)
                        self.viewContext.trySave("Updating delay time interval segment value in Settings", loc: "Settings_CheckedView")
                    })
                }
                .isHidden(picker1 == 2 ? false: true)
            }
        }
        .navigationBarTitle(Text("Completed Items"))
        .navigationBarColor(UIColor.ezDarkAquaSet)
        .onAppear(perform: {
            self.picker1 = Int(settings.autoDeleteSegment)
            self.picker2 = Int(settings.deleteDelaySegment)
            
            //Tried this second, also no affect
            //UITableView.appearance().separatorStyle = .none
        })
        .listSeparatorStyle(style: .none) //Last try, also no affect, see code for this below.
    }
}

extension View {
    func listSeparatorStyle(style: UITableViewCell.SeparatorStyle) -> some View {
        ModifiedContent(content: self, modifier: ListSeparatorStyle(style: style))
    }
}

struct ListSeparatorStyle: ViewModifier {
    let style: UITableViewCell.SeparatorStyle
    
    func body(content: Content) -> some View {
        content
            .onAppear() {
                UITableView.appearance().separatorStyle = self.style
            }
    }
}

所以你基本上可以从上到下看到我尝试过的但没有任何效果。它们基本上都是不同的实现方式.separatorStyle。当我尝试在 UIKit 中做这样的事情并且这被称为静态 UITableView 时，这正是我要删除它的方法。但我不确定我在这里做错了什么。我在网上找到的所有示例都是引用列表而不是表单，所以也许这就是它不起作用的原因。有什么建议么？

添加.listRowSeparator(.hidden)到每个组件

 TextField("Enter first name", text: $firstName)
     .textFieldStyle(.roundedBorder)
     .listRowSeparator(.hidden)
 TextField("Enter last name", text: $lastName)
     .textFieldStyle(.roundedBorder)
     .listRowSeparator(.hidden)
