Apple has rewritten the rules of its own gatekeeping — and this time the language has teeth.

On Friday, Apple updated its App Review Guidelines with some of the sharpest enforcement language it has ever aimed at its developers, according to 9to5Mac. The headline target: AI-powered "nudify" apps and the bait-and-switch tricks that keep them slipping through review.

Section 1.2, which governs user-generated content, now explicitly names "nonconsensual intimate imagery" as one of the content challenges apps must police. Developers who don't build safeguards — or who fail to fix violations after being warned — can now be found in violation of the Developer Code of Conduct itself, the rulebook that decides whether a developer is allowed in the ecosystem at all.

The more striking addition is a brand-new rule, section 2.5.19, aimed at apps that lie during review. Some developers have been submitting innocuous-looking apps that pass App Review, then activating their real — and sometimes harmful — functionality afterward. Apple now says outright that hiding undocumented features, including through code obfuscation, is grounds not just for pulling the app, but for terminating the developer's account entirely.

And the crackdown extends beyond the App Store. Under Section 5, apps facilitating human trafficking or the exploitation of children will be "removed from the App Store and blocked from alternative distribution" — a warning that even the EU's third-party marketplaces can't serve as a safe haven.

The context explains the urgency. In January, the Tech Transparency Project identified dozens of AI "nudify" apps on the store; an April follow-up found Apple's own search suggestions and ads were steering users toward them. In July, San Francisco officials ordered Apple to pull eight apps capable of generating nonconsensual intimate imagery. The same month, a 9to5Mac investigation exposed apps disguising gambling platforms as kids' games — behaving innocently everywhere except from Brazilian IP addresses, where the casino appeared. And the Grok saga saw lawmakers and advocacy groups demand Apple remove X and Grok after the chatbot was used to generate sexualized images of women and minors; Apple confirmed it had privately warned xAI the app could be booted.

All of that explains why Friday's update reads less like a policy refresh and more like an admission: the old wording wasn't working. The new rules are explicit, the penalties are severe, and the jurisdiction is total — no hiding code, no sideloading around it.

The question now is enforcement. Apple has written strict rules before and then enforced them unevenly — the nudify apps the TTP flagged in January were on a store whose rules already banned this content. The new language closes the loopholes developers were exploiting. Whether Apple actually pulls the worst offenders — and whether heavyweight names like Grok face real consequences — is the part that decides whether this is a turning point or just a new paragraph.
