Which icon sizes are included in the generated set?

It generates all 13 required iOS sizes, ranging from 20x20 notification icons and 29x29 settings icons up to the 1024x1024 master icon for the App Store.

Can I download the icons as PNG files directly?

The skill generates an HTML artifact that includes a script to convert the embedded SVG designs into downloadable PNGs using a browser canvas.

Does this skill follow Apple's Human Interface Guidelines?

Yes, it is programmed to prioritize simplicity, distinctiveness, and optical balance while avoiding discouraged elements like photography or thin lines that disappear at small sizes.

Does it handle the iOS squircle shape correctly?

Yes, the skill uses specific SVG path logic and superellipse formulas to replicate the authentic Apple squircle shape (n≈5) rather than a simple CSS border-radius.

The iOS App Icon Generator skill streamlines the mobile design workflow by guiding Claude through a two-phase creative process. It begins by establishing a rigorous visual philosophy—covering core concepts, color psychology, and silhouette tests—before generating a high-fidelity SVG master using the authentic Apple superellipse (squircle) mask. The skill produces a self-contained HTML artifact that displays the icon across all 13 standard iOS and iPadOS sizes and includes a built-in utility to convert and download the designs as production-ready PNGs, ensuring your app looks professional on everything from the lock screen to the App Store.
