在 SwiftUI 中使用绑定值添加和删除列表部分

Question

我尝试使用绑定值在列表中添加和删除部分，因此当添加或删除项目时，将在列表中添加和删除部分的“listSectins”。

   @State private var listSectins = ["SectionOne", "SectionTwo"]
    
     var body: some View {
            
            NavigationView {
                    List(selection: $selection) {
                            Section {
                            ForEach(self.firstSectionData) { rowData in
                                MainMenuRowView(rowData: rowData)
                            }
                            .onMove(perform: { indices, newOffset in
                                self.groupData.rowsGroup[0].move(fromOffsets: indices, toOffset: newOffset)
                            })
                        }
                        .listRowInsets(EdgeInsets(top: 0, leading: 0, bottom: 0, trailing: 0))
        }
    }

我尝试下面的代码及其工作

 List(selection: $selection) {
            if self.isEditMode {
                Section {
                    ForEach(self.firstSectionData) { rowData in
                        MainMenuRowView(rowData: rowData, isEditMode: self.isEditMode)
                    }
                    .onMove(perform: { indices, newOffset in
                        self.groupData.rowsGroup[0].move(fromOffsets: indices, toOffset: newOffset)
                    })
                }
                .listRowInsets(EdgeInsets(top: 0, leading: 0, bottom: 0, trailing: 16))
            }
