Ultimately, I'm simply trying to delete the asset:
  [PHAssetChangeRequest deleteAssets:@[asset]];

You're right, of course, that I've overlooked the fine print: it wants an array 
of “asset URLs previously retrieved from an ALAsset object.” I'm not quite 
certain what that means, exactly.

I'm able to delete the asset by using:
  [[NSFileManager defaultManager] removeItemAtURL: self.sourcePlayListItem.url 
error:&error];
but I think the new 'photo asset' way is preferred in iOS8+, so I thought I'd 
try to be compliant.
