App Icon Validation and Review Issues: How to Investigate

Classify the failure

Save the exact error, affected build and asset. A missing file, a mismatched pixel dimension and a rights complaint are different problems. Reproduce the affected condition before changing the icon, and keep the original asset for comparison.

Check files and the manifest

Confirm that every filename referenced by Contents.json exists with matching capitalization. In a legacy per-size manifest, size is expressed in points and scale is a value such as 2x, not @2x. For the modern iOS export, inspect the 1024×1024 source and its appearance entries.

Check opacity in the correct context

The standard iOS raster icon needs a full-bleed opaque image. Dark or tinted assets and layered workflows have different treatment requirements, so do not apply a blanket ban on transparency to every layer on every platform. Fix the asset named by the validator.

Review accuracy and rights

App metadata must represent the app accurately, and developers are responsible for rights to materials used in icons. Apple’s accurate-metadata rules are the relevant starting point. A generic symbol, unusual color or use of lettering is not by itself proof of a rejection reason.

Verify before resubmitting

Build the corrected project, inspect the installed icon and address each review issue explicitly. Avoid promising a guaranteed approval: validation cannot establish all legal or review requirements. Do not repeatedly swap unrelated artwork without understanding the reported problem.

IconBundlr export and purchase scope

IconBundlr’s native iOS export contains three 1024×1024 PNG appearance assets (light, dark and tinted) and Contents.json inside AppIcon.appiconset. Appearance processing is best-effort: if foreground extraction cannot produce a distinct variant, a slot can reuse the light artwork. Review each result in Xcode. This is an iOS asset catalog, not an Icon Composer .icon file or a complete Android, macOS, watchOS, tvOS or visionOS package.

IconBundlr is free to download, with limited free generation. Available in-app purchase options can include a renewing subscription, lifetime export access and individual-icon unlock credits. The app shows the current price, included access, renewal terms and any eligibility requirements in your storefront before purchase. A subscription is not a lifetime purchase, and an icon credit does not grant unlimited generation.

Review generated artwork before publishing. An export purchase does not guarantee originality, exclusivity, trademark clearance or App Store acceptance. Check your inputs and any third-party artwork, fonts or marks against their applicable rights and the app’s terms. Read the terms.
