AVCapturePhotoOutput capturePhotoWithSettings:delegate: No active and enabled video connection' - swift

Question

Hi I am fairly new to coding and I ran into this error with AVCapturePhotoOutput. I am using Swift 5 and Xcode 12.5.1. I'm running it on my actual device and I have been stuck on it for awhile. The error only occurs when I try to capture a photo. Any help would be greatly appreciated thank you :)
private let output = AVCapturePhotoOutput()
private var captureSession: AVCaptureSession?
private let previewLayer = AVCaptureVideoPreviewLayer()
private let cameraView = UIView()
t
private func setUpCamera() {
let captureSession = AVCaptureSession()
if let device = AVCaptureDevice.default(for: .video) {
do {
let input = try AVCaptureDeviceInput(device: device)
if captureSession.canAddInput(input) {
captureSession.addInput(input)
}
if captureSession.canAddOutput(output) {
captureSession.addOutput(output)
}
// Layer
previewLayer.session = captureSession
previewLayer.videoGravity = .resizeAspectFill
cameraView.layer.addSublayer(previewLayer)
captureSession.startRunning()
captureSession.sessionPreset = AVCaptureSession.Preset.high
self.captureSession = captureSession
}
catch {
print(error)
}
}
}
t
Extension CameraViewController: AVCapturePhotoCaptureDelegate {
func photoOutput(_ output: AVCapturePhotoOutput, didFinishProcessingPhoto photo: AVCapturePhoto, error: Error?) {
guard let data = photo.fileDataRepresentation(),
let image = UIImage(data: data) else {
return
}
captureSession?.stopRunning()
showEditPhoto(image: image)
}
private func showEditPhoto(image: UIImage) {
guard let resizedImage = image.sd_resizedImage(
with: CGSize(width: 640, height: 640),
scaleMode: .aspectFill
) else {
return
}
let vc = PostEditViewController(image: resizedImage)
if #available(iOS 14.0, *) {
vc.navigationItem.backButtonDisplayMode = .minimal
}
navigationController?.pushViewController(vc, animated: false)
}

Try using ‘ cgImageRepresentation()’ instead of ‘ fileDataRepresentation()’. And init a UIImage from the given cgImage
