App Icon Generator

Generate an app icon programmatically with a CoreGraphics Swift script, resize it to every required size, and install it into the Xcode asset catalog — with appearance variants (light/dark/tinted).

Read first — the Liquid Glass era (iOS 26 / macOS 26)

Apple icon standards verified as of July 2026 — Icon Composer, Xcode 26, macOS Tahoe 26.4+. This guidance is static (the skill does no per-run web lookup); if that date is well in the past or the OS has moved on, re-verify against the HIG · App icons before trusting the specifics below.

Apple's shippable icon format changed. On iOS 26 / macOS 26 the modern app icon is a layered, light-responsive Liquid Glass icon authored in Icon Composer (free; ships with Xcode 26, needs macOS Tahoe 26.4+). You supply flat artwork in up to four depth groups (background → foreground); the system renders the glass — specular highlights, refraction, translucency, shadows — and masks the rounded-rect shape. One .icon file adapts across iPhone, iPad, Mac, and Apple Watch and across Default / Dark / Mono (tinted) appearances.

So this skill does NOT produce the final iOS 26 icon. Icon Composer is GUI-first; no script can author a true layered .icon. Its two honest roles are:

1. Placeholder — a fast flat 1024 PNG so early builds, TestFlight, and screenshots feel real before you invest in the real icon.
2. Layered source art — flat background / midground / foreground PNGs (or SVGs), effect-free, ready to drag into Icon Composer, where you assemble depth and export the .icon.
