Apple Developer News:

As outlined in our App Review Guidelines, pornographic material
has long been prohibited on the App Store — this includes apps
that generate nudity or sexually explicit imagery, such as
“nudification” apps that create sexually explicit images of real
individuals without their consent. Apps that host user-generated
content are required to filter objectionable material, give users
a way to report offensive content, and let users block abusive
accounts. Apps containing hidden or undocumented features are also
prohibited on the App Store, including apps that misrepresent
their purpose during review and only reveal harmful capabilities — such as “nudification” — after approval, a tactic commonly
known as bait-and-switch.

Their post includes the specific changes to the guidelines. Let’s hope the guideline changes are accompanied by better enforcement.

Of course, it’s worth noting that the best known perpetrator of AI-generated non-consensual nudification is X, which (checks notes) is where Apple executives do all their social media posting, and which, yes, I argue once again marks the spot in the zeitgeist. The zeitgeist is not clean.
