But you don't yet HAVE an asset; you seem to only have a regular file on disk, in an application's Documents directory. Do you want to do more than simply delete the file? If not, what compels you to turn it into a PHAsset first?

No doubt something you would retrieve by -[asset valueForProperty: ALAssetPropertyURLs] (if you had an ALAsset * called asset.) But I imagine that's a red herring here.

What inspires that statement?
If you have a PHAsset representing something in a PHAssetLibrary, then sure, you would use such an approach to delete the asset. But what you've shown us so far seems to imply that you just have a plain old .MOV file, perhaps created by the user, sitting in the app's sandbox.
In your original example, where does self.sourcePlayListItem.url come from? What does the URL represent?
