Most rejections come from transparency, wrong dimensions (must be exactly 1024x1024), non-PNG format, or pre-rounded corners that conflict with iOS's own mask. Apple rejects builds at submission, so catching these locally saves a round trip.
Exactly 1024x1024 pixels for the App Store icon (the marketing icon). Xcode generates the smaller home-screen sizes automatically. The master must be 1024x1024 PNG without transparency.
No. The 1024x1024 App Store icon must be fully opaque. Flatten any transparent areas onto a solid background color before submission.
No. iOS applies its own continuous-corner mask. Submit a square icon and let iOS round it. Pre-rounding causes double-clipping or visible gaps.
Use Pixelle's AI app icon generator to create a compliant icon from a text prompt. It produces 1024x1024 PNGs without transparency by default, ready to drop into Xcode.
