Hi iOS community need your help. I am working on an application where I am capturing photo from the back camera using AVCaptureSession. It is working fine with the devices running iOS17+ but I am facing an error on device iPhone X running iOS 16.7.4 ERROR: ` error: Optional(Error Domain=AVFoundationErrorDomain Code=-11803 "Cannot Record" UserInfo={NSUnderlyingError=0x283f0b780 {Error Domain=NSOSStatusErrorDomain Code=-16409 "(null)"}, NSLocalizedRecoverySuggestion=Try recording again., AVErrorRecordingFailureDomainKey=3, NSLocalizedDescription=Cannot Record}) My Code here: final class CedulaScanningVC: UIViewController { var captureSession: AVCaptureSession! var stillImageOutput: AVCapturePhotoOutput! var videoPreviewLayer: AVCaptureVideoPreviewLayer! var delegate: ScanCedulaDelegate? override func viewDidLoad() { super.viewDidLoad() } override func viewWillAppear(_ animated: Bool) { super.viewWillAppear(animated) } override func viewWillDisappear(_ animated: Bool) { super.viewWillDisappear(animated) self.captureSession.stopRunning() } override func viewDidAppear(_ animated: Bool) { super.viewDidAppear(animated) setupCamera() } // MARK: - Configure Camera func setupCamera() { captureSession = AVCaptureSession() captureSession.sessionPreset = .medium guard let backCamera = AVCaptureDevice.default(for: AVMediaType.video) else { print("Unable to access back camera!") return } let input: AVCaptureDeviceInput do { input = try AVCaptureDeviceInput(device: backCamera) //Step 9 stillImageOutput = AVCapturePhotoOutput() if captureSession.canAddInput(input) && captureSession.canAddOutput(stillImageOutput) { captureSession.addInput(input) captureSession.addOutput(stillImageOutput) setupLivePreview() } } catch let error { print("Error Unable to initialize back camera: \(error.localizedDescription)") } } func setupLivePreview() { videoPreviewLayer = AVCaptureVideoPreviewLayer(session: captureSession) videoPreviewLayer.videoGravity = .resizeAspectFill videoPreviewLayer.connection?.videoOrientation = .portrait self.view.layer.addSublayer(videoPreviewLayer) //Step12 DispatchQueue.global(qos: .userInitiated).async { [weak self] in self?.captureSession.startRunning() //Step 13 DispatchQueue.main.async { self?.videoPreviewLayer.frame = self?.view.bounds ?? .zero } } } func failed() { let ac = UIAlertController(title: "Scanning not supported", message: "Your device does not support scanning a code from an item.

Hi I am using UIActivityViewController to share content on social networks but facing one issue. The issue is when i select the share button the UIActivityViewController gets appear and I select the Facebook option. I select the Facebook option in the sharing sheet -> Facebook sharing view appears with two options (Cancel and Next). When I select the Cancel button giving me another action sheet to discard or keep the post. When i select to discard the Action Sheet get disappear but the Facebook sharing view still keep showing and there is no way to go back. Second when I press the next button in the Facebook sharing view -> another Facebook view gets appear with two buttons (Cancel and Share).... When I click the share button content get share on Facebook and black screen appears with a check in circle and text "Shared to Facebook!" .. And the application get stuck on this Screen. Below is my code, Any help would be appreciated, I am also using the activityViewController!.completionWithItemsHandler but this closure not getting called in case of Facebook. let url = "\(UserDefaults.baseURL)/pl/\(resource)/\(sharingId)" // set up activity view controller let imageToShare = [ url ] activityViewController = UIActivityViewController(activityItems: imageToShare, applicationActivities: nil) activityViewController!.popoverPresentationController?.sourceView = self.view // so that iPads won't crash // exclude some activity types from the list (optional) activityViewController!.excludedActivityTypes = [UIActivity.ActivityType.airDrop] activityViewController!.completionWithItemsHandler = { (activityType: UIActivity.ActivityType?, completed: Bool, arrayReturnedItems: [Any]?, error: Error?) in if completed { print("share completed") self.dismiss(animated: true) return } else { print("cancel") self.dismiss(animated: true) } if let shareError = error { print("error while sharing: \(shareError.localizedDescription)") } } // present the view controller self.present(activityViewController!, animated: true, completion: nil)
