[Bug?] App Craches when using Destructive Button in SwipeActions In Child View

Forums > SwiftUI

Using SectionedFetchRequest to show each item per section in the Child view.

The problem occurs when

  1. the ChildView has only one item in one section.
  2. when deleting that item with a Destructive Button in a SwipeAction, the app crashes with the message "Thread 1: EXC_BREAKPOINT".
  3. there is nothing in the debugging.

I googled the issue and found that removing the Button's role:.destructive fixes the problem.

struct MainCatalogDetailView: View {
    @Environment(\.managedObjectContext) private var moc
    @SectionedFetchRequest<String, ItemEntity> private var items: SectionedFetchResults<String, ItemEntity>

    private let filter: FilterType
    private let name: String
    private let catalog: Catalog

    init(filter: FilterType, name: String, sectionIdentifier: KeyPath<ItemEntity, String>, sortDescriptors:[SortDescriptor<ItemEntity>], catalog: Catalog) {
        self.filter = filter = name
        self.catalog = catalog
        _items = SectionedFetchRequest<String, ItemEntity>(sectionIdentifier: sectionIdentifier,
                                                           sortDescriptors: sortDescriptors,
                                                           predicate: NSPredicate(format: "%K == %@", catalog.filterKey, name))

    @State private var selectedItem: ItemEntity? = nil
    @State private var selectedItemToEdit: ItemEntity? = nil
    @State private var showingAddView = false

    @State private var searchText = ""

    var body: some View {
            List {
                ForEach(items) { category in
                    Section {
                        ForEach(category) { item in
                            MainListRowView(item: item)
                                .swipeActions(edge: .trailing) {
                                    Button { // here
                                        delete(item: item)
                                    } label: {
                                        Label("Delete", systemImage: "trash")
                                    Button {
                                        selectedItemToEdit = item
                                    } label: {
                                        Label("Edit", systemImage: "square.and.pencil")
                                .onTapGesture {
                                    selectedItem = item

                    } header: {
                        headerView(category:, count: category.count)
                    .listRowInsets(EdgeInsets(top: 10, leading: 10, bottom: 10, trailing: 10))
