Obtain NSURL from UIImagePickerController

Question

I'm attempting to grab the file path of an image selected through an imagePickerController in order to upload the file to Firebase Storage.

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {

    mediaUploadView.image = info[UIImagePickerControllerOriginalImage] as? UIImage

    let localUrl: NSURL = (info[UIImagePickerControllerReferenceURL] as! NSURL)
    print(localUrl)

    let localFile: NSURL = localUrl
    let mediaRef = storageRef.child("media")

    let uploadTask = mediaRef.putFile(localUrl, metadata: nil) { metadata, error in
        if (error != nil) {
        } else {
            let downloadURL = metadata!.downloadURL
        }
    }


    self.dismissViewControllerAnimated(true, completion: nil)

}

The output reads:

assets-library://asset/asset.JPG?id=C224DA06-6B7B-4BE2-8F5E-2EC7BC8B0526&ext=JPG
Body file is unreachable: /asset.JPG
Error Domain=NSCocoaErrorDomain Code=4 "The file doesn’t exist."

It grabs what I believe is the NSURL, but then is unable to find it for upload.

I have attempted to follow along with this similar problem on stack "How do I get Image reference and upload image to Firebase?" but the output then simply returns nil. Any help would be great, thank you!

I had trouble getting the info[UIImagePickerControllerOriginalImage] to work. I had to do it like this:

let assets = PHAsset.fetchAssetsWithALAssetURLs([localUrl], options: nil)
let asset = assets.firstObject
asset?.requestContentEditingInputWithOptions(nil, completionHandler: { (contentEditingInput, info) in
    let imageFile = contentEditingInput?.fullSizeImageURL
    // now call putFile with imageFile instead of localURL
