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. Please use a device with a camera.", preferredStyle: .alert)
    ac.addAction(UIAlertAction(title: "OK", style: .default))
    present(ac, animated: true)
    captureSession = nil
}

// MARK: - actions

func cameraButtonPressed() {
    let settings = AVCapturePhotoSettings(format: [AVVideoCodecKey: AVVideoCodecType.jpeg])
    stillImageOutput.capturePhoto(with: settings, delegate: self)
}

  }


  extension CedulaScanningVC: AVCapturePhotoCaptureDelegate {

func photoOutput(_ output: AVCapturePhotoOutput, didFinishProcessingPhoto photo: AVCapturePhoto, error: Error?) {
    
    print("error: \(error)")
    captureSession.stopRunning()
    DispatchQueue.main.asyncAfter(deadline: .now() + 1.0) { [weak self] in
        
        guard let self = self else {return}
        guard let imageData = photo.fileDataRepresentation()
            else {
            print("NO image captured")
            return
            
        }
        
        let image = UIImage(data: imageData)
        self.delegate?.capturedImage(image: image)
    }
}
}

I don't know what am doing wrong ?
