Apple integrated iCloud Drive in iOS from iOS 8. That makes a good sense since whenever you delete something that goes to a folder in iCloud Drive called Recently Deleted. No matter whether you delete images or videos or files or anything else, it will be stored in Recently Deleted folder in iCloud Drive and this is possible to restore deleted files from iCloud Drive.
However, some people do not know that iOS stores deleted files in iCloud Drive for 30 days and then it deletes those files one by one. At the same time, some people want to delete files permanently. They do not want to store them in iCloud Drive. Instead, they want them deleted once they delete it from the Camera Roll or Album, which is generally not possible with default options.

Here is a trick that will let you delete photos from iOS 8 permanently. You do not have to go to the Recently Deleted folder in iCloud Drive in order to get them erased permanently.
