What's in the asset catalog
An AppIcon.appiconset is a folder of PNGs plus a Contents.json that tells Xcode which file maps to each idiom, size, and scale — iPhone notification, settings, spotlight and app icons at @2x/@3x, the equivalent iPad sizes at @1x/@2x, the iPad Pro 83.5pt icon, and the 1024px App Store marketing icon. This tool renders each size from your source image and writes the matching Contents.json for you.
Icon requirements
- Square, in PNG with no transparency or alpha channel.
- 1024×1024 source recommended; smaller images are upscaled.
- No rounded corners or drop shadows — iOS adds the mask.
- sRGB color, flattened onto an opaque background.
