Icon Composer App Icon Workflow

Purpose

Use this skill to help a user learn and operate Apple's Icon Composer workflow for app icons. The skill owns the design-production path from brief to layered source artwork, Icon Composer GUI work, preview export, and Xcode handoff. It does not replace visual judgment, source artwork tools, Xcode execution skills, or product-design iteration.

When To Use

• Use this skill when the user asks for help with Apple's Icon Composer.
• Use this skill when the task mentions .icon files, Liquid Glass app icons, Icon Composer documents, app icon appearance modes, or ictool.
• Use this skill for app icon workflows targeting iOS, iPadOS, macOS, watchOS, or Xcode app projects.
• Use this skill when the user wants Codex to guide or operate the Icon Composer GUI through Computer Use.
• Use this skill when the task is to export rendered preview PNGs from an Icon Composer document.
• Do not use this skill for generic logo design unless the logo is being prepared as an Apple app icon.
• Do not use this skill for ordinary Xcode build, run, signing, asset-catalog, or project-file work after the app icon handoff is complete.
• Recommend bootstrap-xcode-app-project when the app project does not exist yet.
• Recommend xcode-build-run-workflow when the next step is adding the .icon file to an existing Xcode project, choosing it in the Project Editor, building, running, or inspecting project state.
• Recommend explore-apple-swift-docs when the user needs a fresh Apple documentation research pass before icon-production work continues.
