⚡ Recommended focus areas for review Potential Memory Leak Removing currentDownloadOperation?.cancel() may cause the view controller to be retained by the ongoing download operation if the operation holds strong references to self (via delegates or completion closures). This would prevent the view controller from being deallocated until the download completes, wasting memory. If the download is intended to continue in the background after the user navigates back, consider transferring ownership to a separate download manager that outlives the view controller rather than keeping it as a property of this view controller. override func viewWillDisappear(_ animated: Bool) { super.viewWillDisappear(animated) navigationController?.navigationBar.transform = .identity let currentCell = (collectionView.cellForItem(at: currentIndex) as? PreviewCollectionViewCell) currentCell?.didEndDisplaying() previewErrors.values.compactMap { $0 as? OfficePreviewError }.forEach { $0.downloadTask?.cancel() } UIApplication.shared.endReceivingRemoteControlEvents() resignFirstResponder()
