The phone has enough metadata to make that easy to expose, at least in the simple case. There's GPS location, time, and even your Face ID verification (on iPhone X) to prove that it was really you holding the camera.

If you make your fake video after the event, the location and time will be obviously off.

Which are all values written by the camera. My camera will believe it's whatever time, location, and face I tell it.

The point by clarkmoody was that Apple would be signing the photos with their key to ensure those values are correct.

It would be basically the macOS Developer ID software model applied to photos.

You can set the time on your phone, and GPS spoofing is a technology that already exists -- or you could disable location services.
