iOS AppIcon.appiconset — Contents.json

Drop this into Assets.xcassets/AppIcon.appiconset/Contents.json alongside a single 1024×1024 icon-1024.png — this example configures one standard iOS source image. It does not configure other platforms, separate dark/tinted artwork, or Icon Composer layers.

Key Rules

Don't Resize By Hand

IconBundlr’s native iOS export contains standard, dark and tinted 1024×1024 PNG files plus Contents.json inside AppIcon.appiconset. Appearance processing is best-effort: a slot can reuse the standard artwork if a distinct variant cannot be produced. Inspect each appearance in Xcode. Other platform assets and Icon Composer documents require separate preparation. Export access is subject to the options shown in the app.
