只需添加到上面， 对于Swift 3.0，它对我有用.

Just to add to the above, For swift 3.0 this worked for me.

PHPhotoLibrary.shared().performChanges({
                let imageAssetToDelete = PHAsset.fetchAssets(withALAssetURLs: imageUrls as! [URL], options: nil)
                PHAssetChangeRequest.deleteAssets(imageAssetToDelete)
            }, completionHandler: {success, error in
                print(success ? "Success" : error )
            })
