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.
Reference reviewed September 5, 2026. Apple asset catalogs and Icon Composer describe the current workflows. The copied manifest references only the single iOS image named below.
Key Rules
- Format: PNG, square (1:1). The standard iOS raster appearance uses an opaque master. Other appearances, layers and platform workflows have separate requirements.
- No rounded corners on iOS: the system applies the mask automatically — deliver square art.
- Color space: sRGB or Display P3.
- Asset-catalog sizing: for a target using Single Size, supply the requested high-resolution source, such as a single 1024×1024 image for standard iOS sizing. Separate appearance artwork and layered workflows need their own configuration. Use individual sizes when your target or artwork requires them.
- watchOS icons are circular: the system applies a circular mask — keep critical content inside the circle.
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.
