I don't think the actual delay is necessary. If you just use DispatchQueue.main.async {} it seems to solve it as well. I'm just not sure what the side effects of this would be?

Did anything come of your DTS?

Ok, so that means using PHAsset.fetchAssets() correct? Are there any examples showing how I can take a reference from the PHPhotoLibrary and store it in something like CoreData and then reference it later from a list view?
