Key points
- AI researcher Derik Kauffman discovered a list containing more than 100,000 words and phrases.
- Apple appears to restrict completion suggestions for entries included in the list.
- The same restriction reportedly extends to the keyboard's swipe-gesture function.
Context
For developers and technical decision-makers, the case shows that text assistance built into an operating system can constrain user journeys in ways that are not immediately apparent. Platform-dependent input behavior therefore belongs in end-to-end testing and architectural reviews.
What this means for you
Directly applicable
For you, this means testing iPhone predictive text and swipe flows as platform-dependent interface behavior, including cases where expected completions are withheld.
Who benefits: Developers and technical decision-makers who own iOS-facing user journeys can use the finding to identify where restricted completions may affect usability.
