Create Apple-platform app icons from product context, generate polished
Generates iOS app icons as PNG imagesets for Xcode asset catalogs from SF Symbols or Iconify API. Use when creating icon assets, adding icons to asset catalog, or searching for icons.
Generates iOS app icon PNG imagesets for Xcode asset catalogs from SF Symbols (5,000+ Apple native) or Iconify API (275k+ open-source icons).

Create Apple-platform app icons from product context, generate polished candidates, test small-size recognition, and install valid iOS or macOS icon assets.
This icon should make <target user> remember <app name> as the app for <core job/emotion>, using <simple visual metaphor>.

Contents/Resources, but the silhouette must still survive at 32 and
16 px.ASSETCATALOG_COMPILER_APPICON_NAME;
manually packaged macOS apps usually need CFBundleIconFile or
CFBundleIconName plus a copied resource.Score recognition at small sizes, memory, category fit, differentiation, shelf appeal beside real icons, brand fit, and technical readiness.
