How to fetch newly created object from PHObjectPlaceholder after change request completes

Question

I'm using the new Photos framework and I'm saving a video to my photo roll:

   let assetRequest = PHAssetChangeRequest.creationRequestForAssetFromVideoAtFileURL(url)
    assetPlaceHolder = assetRequest?.placeholderForCreatedAsset

A short time later in my success handler after the video has been saved to the photo library I can reference the assetPlaceHolder object and it's looking like a valid PHObjectPlaceholder object. I'm just unsure from looking at Apple's documentation how to get at the actual video or url to the video that's been saved.

This code is untested, but it pretty much works like this:

let assets:PHFetchResult = PHAsset.fetchAssetsWithLocalIdentifiers([assetPlaceHolder!.localIdentifier], options: nil)

if let asset = assets.firstObject as? PHAsset {
     PHImageManager.defaultManager().requestPlayerItemForVideo(asset, options: PHVideoRequestOptions(), resultHandler: {
        (result, info) in
        //result: AVplayerItem?

}
