Adding Icon Composer icons to Xcode

Xcode 26 introduces Icon Composer, a new tool for creating app icons using the Liquid Glass design system. Instead of manually adding icon variants to asset catalogs, developers can now drag a single .icon file into their Xcode project navigator. The tool allows importing SVG layers from design applications and applying backgrounds, effects, and styling within Icon Composer. However, alternate app icons still require manual export and addition to asset catalogs, limiting the tool's full potential.
