I use this method to save the image taken via camera

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    print(info)
    var selectedImage: UIImage!
    if let image = info[UIImagePickerControllerEditedImage] as? UIImage {
        selectedImage = image
    } else if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
        selectedImage = image
    }
    self.profileImageView.image = selectedImage

    if (picker.sourceType == UIImagePickerControllerSourceType.camera) {

        let imgName = UUID().uuidString
        let documentDirectory = NSTemporaryDirectory()
        let localPath = documentDirectory.appending(imgName)

        let data = UIImageJPEGRepresentation(selectedImage, 0.3)! as NSData
        data.write(toFile: localPath, atomically: true)
        let photoURL = URL.init(fileURLWithPath: localPath)


    }
}

Delegate didFinishPickingMediaWithInfo gets called after a pic is taken using the camera. UIImagePickerControllerReferenceURL object will be nil as the image has not been saved to the camera roll yet.

To get rid of this situation, you need to first save the image and then use the url of the path you saved. You can however use UIImagePickerControllerOriginalImage property on info to show the taken image in your application. Hope this helps!
