iOS Swift - Not able to use video from Library

I'm trying to obtain a video from the library in my swift app. I'm using the following code snippet :

 print("ChatDetailsController - imgaction - Vid from Lib pressed")
        self.selection = "videoLib";
        self.imgSelection = "vidFromLib"
        self.imagePicker.sourceType = .PhotoLibrary
        self.imagePicker.delegate = self
        self.imagePicker.mediaTypes = ["public.movie"]
        self.presentViewController(self.imagePicker!, animated: true, completion: nil)

Then in delegate method:

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject])
{
    if(selection == "videoLib")
    {
    if let videoURL = info[UIImagePickerControllerReferenceURL] as? NSURL
        {


            print("imagePickerController - reached for video - from Lib - \(videoURL)")
            let videoData = NSData(contentsOfURL: videoURL)

         }   
   }

}

When running the app, it shows the library and I can select a video, then it says compressing video.. but then the app crashes.

The Crash happens when I try to access the videoData Variable becuase it wasn't able to get the actual data since the path is an asset path and not a video path.

The Log shows something similar to this:

fatal error: unexpectedly found nil while unwrapping an Optional value

The print function shows:

imagePickerController - reached for video - from Lib - assets-library://asset/asset.MOV?id=7D3BFA00-A7CB-470C-8899-F82FCC2CBC54&ext=MOV

Also, right after choosing/selecting the video, a message similar to this is displayed in the console/log:

[Generic] video path /var/mobile/Media/PhotoData/CPLAssets/group419/A2901DD1-FDEF-423B-B4A3-E808B9AC45E1.MOV for PLPreviewImageAndDurationForVideoAtPath does not exist

Of course the file name changes on every run.

I'm able to get a video and images from the camera, and getting images from the library, I'm only having trouble with using the the video from the library. I would expect to see the video URL similar to :

/var/mobile/Containers/Data/Application/BEDDC883-B20E-496D-8C9A-A40EC0A29214/Documents/63ea24932c101b76c72fcbae3993fc9b.mov for example; where the video file is in the application and not showing as an unusable asset URL. Any help would be appreciated.

The problem is that you're trying to fetch the wrong video. You're trying to use info[UIImagePickerControllerReferenceURL]. What you want is info[UIImagePickerControllerMediaURL].
