What this guideline means in practice
If users can put content into your app, by posting, uploading, commenting, chatting, or prompting a model to generate images, text, audio, or video, Guideline 1.2 applies. AI content creation apps are now named explicitly, next to social media and UGC platforms.
Every such app needs four safeguards: a method for filtering objectionable material before it is posted, a way to report offensive content with timely responses, the ability to block abusive users, and published contact information.
Enforcement is stricter on paper. If Apple finds violating content, it asks you to remove it and to send a plan to improve compliance. Failing to implement safeguards, or failing to fix violations after notice, may now count as a Developer Code of Conduct violation (Guideline 5.6), which puts your developer account at risk, not just one app.
