Is there a way to prevent or handle our application's crash if a third-party library makes a bad memory access? Basically, I want to know if using a buggy library (that causes bad memory access) will automatically make our application inherit those crashes, leading to our app crashing as well. If there is a way to prevent the crash, what methods can be used to do so? Thread 13: EXC_BAD_ACCESS (code=1, address=0x3a7d300)

QLPreview keeps blinking and stops previewing the file when opening some high-resolution PDF files with heavy content. This can only be simulated in a real device built in xcode simulators cant simulate the issue. Tested in Xcode Version 15.4 (15F31d) and iPadOS Version 17.5.1. Following is My Sample code : import UIKit import QuickLook class ViewController: UIViewController { var currentViewFilePath = "" let preview = QLPreviewController() override func viewDidLoad() { super.viewDidLoad() self.setupQLPreview() loaddata() // Do any additional setup after loading the view. } func loaddata(){ if let fileURL = Bundle.main.url(forResource: "CD28048D", withExtension: "pdf") { self.currentViewFilePath = fileURL.relativePath self.preview.reloadData() // Use the fileURL here print("File URL: \(fileURL)") } else { print("File not found") } } } extension ViewController:QLPreviewControllerDelegate,QLPreviewControllerDataSource{ func setupQLPreview(){ preview.delegate = self preview.dataSource = self self.view.addSubview(preview.view) let previewhight = (UIScreen.main.bounds.height - ((self.navigationController?.navigationBar.frame.height ?? 0))) preview.view.translatesAutoresizingMaskIntoConstraints = false preview.view.topAnchor.constraint(equalTo: self.view.topAnchor).isActive = true preview.view.leftAnchor.constraint(equalTo: self.view.leftAnchor,constant: 4).isActive = true preview.view.rightAnchor.constraint(equalTo: self.view.rightAnchor,constant: -4).isActive = true preview.view.leadingAnchor.constraint(equalTo: self.view.leadingAnchor,constant: 4).isActive = true preview.view.trailingAnchor.constraint(equalTo: self.view.trailingAnchor,constant: -4).isActive = true preview.view.widthAnchor.constraint(equalToConstant: self.view.frame.width-8).isActive = true preview.view.heightAnchor.constraint(equalToConstant: previewhight-4).isActive = true preview.view.bottomAnchor.constraint(equalTo: self.view.bottomAnchor).isActive = true preview.navigationController?.isNavigationBarHidden = true self.addChild(preview) preview.didMove(toParent: self) } func numberOfPreviewItems(in controller: QLPreviewController) -> Int { if self.currentViewFilePath.isEmpty || self.currentViewFilePath == ""{ return 0 }else{ return 1 } } func previewController(_ controller: QLPreviewController, previewItemAt index: Int) -> QLPreviewItem { let fileUrl = URL(fileURLWithPath: self.currentViewFilePath) return fileUrl as QLPreviewItem } } while running the above code Xcode debugger prints following errors: View service did terminate with error: Error Domain=_UIViewServiceInterfaceErrorDomain Code=3 "(null)" UserInfo={Message=Service Connection Interrupted} #Remote Preview collection viewServiceDidTerminateWithError: Error Domain=_UIViewServiceInterfaceErrorDomain Code=3 "(null)" UserInfo={Message=Service Connection Interrupted} #Remote [u 0AA9D4C5-BBA1-56F6-8FFF-F5F56B99399A:m (null)] [com.apple.quicklook.extension.previewUI(1.0)] Connection to plugin invalidated while in use.
