Frequently Asked Questions about design-diff

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I detect visual differences in iOS UI elements after a design iteration?▼

Visual regression testing for iOS UI compares current interface states against reference snapshots to identify unintended visual changes. This Skill uses Swift Snapshot Testing to generate diff images and Claude Vision to analyze the discrepancies during design iterations.

What is the best way to automate UI diff comparison for design changes?▼

Automating UI diff comparison is achieved by triggering the process with keywords like "design compare" or "UI diff". This applies Swift Snapshot Testing for image comparison and Claude Vision for detailed analysis of the generated diff images to track design changes.

Do I need Swift Snapshot Testing to perform a design audit on my application?▼

Yes, performing a design audit with this Skill requires integration with Swift Snapshot Testing for image comparison, alongside Claude Vision for detailed analysis of the generated diff images to ensure visual consistency across UI updates.

Can I use this approach for visual regression testing across multiple UI versions?▼

Yes, you can use this approach for visual regression testing by comparing current UI states against reference snapshots. It facilitates comparison between design versions to highlight visual discrepancies and ensure visual consistency across UI updates.

How does Claude Vision analyze UI diff images generated by snapshot testing?▼

Claude Vision analyzes UI diff images generated by Swift Snapshot Testing by providing detailed analysis of the visual discrepancies. This detects and compares visual differences in user interface elements to ensure visual consistency.
