Hi all, I have this problem - Expected dequeued view to be returned to the collection view in preparation for display. When the collection view's data source is asked to provide a view for a given index path, ensure that a single view is dequeued and returned to the collection view. Avoid dequeuing views without a request from the collection view. For retrieving an existing view in the collection view, use -[UICollectionView cellForItemAtIndexPath:] or -[UICollectionView supplementaryViewForElementKind:atIndexPath:]. My code crashed just IOS18+ My code - func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { guard let cell = collectionView.dequeueReusableCell(withReuseIdentifier: SectionModsCell.cellIndetifire, for: indexPath) as? SectionModsCell else { return UICollectionViewCell() } switch mainState { case .main: if ApphudManager.sharedInstance.isPremium { let cellData = sectionModsData[indexPath.item] return cell.setupCell(data: cellData) } else { let newIndex = getIndex(for: indexPath) guard indexPath.item != adIndexPath || adIndexPath == 0 else { if UIDevice.current.userInterfaceIdiom == .pad { let bannerCell = collectionView.dequeueReusableCell(withReuseIdentifier: IpadNativeCell.cellIndetifire, for: indexPath) as! IpadNativeCell bannerCell.setupCell(nativeAd: nativeAd) return bannerCell } else { let bannerCell = collectionView.dequeueReusableCell(withReuseIdentifier: SmallNativeCell.cellIndetifire, for: indexPath) as! SmallNativeCell bannerCell.setupCell(nativeAd: nativeAd) return bannerCell } } let cellData = sectionModsData[newIndex] return cell.setupCell(data: cellData) } case .search: let cellData = filteredModsData[indexPath.item] return cell.setupCell(data: cellData) } } And this code not give me error, my mind is **** ( func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { switch mainState { case .main: if ApphudManager.sharedInstance.isPremium { guard let cell = collectionView.dequeueReusableCell(withReuseIdentifier: SectionModsCell.cellIndetifire, for: indexPath) as? SectionModsCell else { return UICollectionViewCell() } let cellData = sectionModsData[indexPath.item] return cell.setupCell(data: cellData) } else { let newIndex = getIndex(for: indexPath) guard indexPath.item != adIndexPath || adIndexPath == 0 else { if UIDevice.current.userInterfaceIdiom == .pad { let bannerCell = collectionView.dequeueReusableCell(withReuseIdentifier: IpadNativeCell.cellIndetifire, for: indexPath) as! IpadNativeCell bannerCell.setupCell(nativeAd: nativeAd) return bannerCell } else { let bannerCell = collectionView.dequeueReusableCell(withReuseIdentifier: SmallNativeCell.cellIndetifire, for: indexPath) as! SmallNativeCell bannerCell.setupCell(nativeAd: nativeAd) return bannerCell } } guard let cell = collectionView.dequeueReusableCell(withReuseIdentifier: SectionModsCell.cellIndetifire, for: indexPath) as? SectionModsCell else { return UICollectionViewCell() } let cellData = sectionModsData[newIndex] return cell.setupCell(data: cellData) } case .search: guard let cell = collectionView.dequeueReusableCell(withReuseIdentifier: SectionModsCell.cellIndetifire, for: indexPath) as? SectionModsCell else { return UICollectionViewCell() } let cellData = filteredModsData[indexPath.item] return cell.setupCell(data: cellData) } }
