Apple unveils SQUIRE, an AI tool for targeted UI edits

Apple introduced SQUIRE, an experimental AI tool for precise UI editing using natural language prompts.

SQUIRE uses an intermediate representation called SQUIREIR to model UIs as component trees with named slots and placeholders.

The system converts that intermediate structure into HTML, CSS, and JavaScript to produce final web components.

A study with 11 frontend developers showed high satisfaction and effective control during design exploration.

SQUIRE currently runs on GPT-4o and is available only to a limited set of participating developers.
