I am developing the front facing camera app in iPad2 by using the UIImagePickerController.

When I capture the image it\'s shows as flipped from left to

It took me few hours, but I think I got there. Here is a working solution for Swift 5.2 of how to get correct image (both in ImagePicker preview and in output).

     //Registering to get notification when users takes a picture

    override func viewDidLoad() {
        NotificationCenter.default.addObserver(forName: NSNotification.Name(rawValue: "_UIImagePickerControllerUserDidCaptureItem"), object: nil, queue: nil) { (notification) in
            self.changePhotoOrientation()
    }

    //Changing image orientation for ImagePicker preview

    func changePhotoOrientation() {
        var subviews: [UIView] = [imagePicker.view]
        while (!subviews.isEmpty) {
            let subview = subviews.removeFirst()
            subviews += subview.subviews
            if (subview.isKind(of: UIImageView.self)) {
                subview.transform = self.imagePicker.cameraViewTransform.scaledBy(x: -1, y: 1)
            }
        }
    }

    //Changing image orientation for the output image

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        if let userPickedImage = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {
            image = UIImage(cgImage: userPickedImage.cgImage!, scale: userPickedImage.scale, orientation: .leftMirrored)
        }
    }

}
