⌨️Apple's Secret Autocomplete Blocklist Has Over 100,000 Banned Words

Your iPhone keyboard has been quietly censoring you

TL;DR

A researcher pulled Apple's hidden list of over 100,000 blocked autocomplete and swipe-type phrases from iOS. It covers slurs, politics, and even 'Santa isn't real.' Worth knowing if you build keyboards or care what your phone quietly decides for you.

Apple is quietly blocking more than 100,000 words and phrases from iPhone autocomplete and swipe-typing, and a researcher just published the whole list. Derik Kauffman posted it online after digging it out of iOS. The list is wild. It includes slurs and sexual or drug terms, sure, but it also blocks 'dictator Trump,' 'covid is a hoax,' and 'illegal immigrant,' plus harmless stuff like 'Santa isn't real' and 'iMessage isn't working.' Why should you care? If you ship anything with text input, this is a real-world case study in how a platform decides what users can't type without fighting it. The list also has inconsistencies, where one phrase is blocked and its near-twin isn't. That's the sort of thing your QA team needs to know exists before a user screenshots it. The researcher found the list using OpenAI's Codex and Anthropic's Claude Code, then converted a hash table back into readable text. Another researcher independently pulled the same data, so this isn't a fluke. Individual lists exist for each language. Users can still type whatever they want or override suggestions, so Apple's stated goal is avoiding inappropriate predictions, not stopping typing.
