# ITMS-90717: Invalid App Store Icon. The App Store Icon in the asset catalog can't be transparent nor contain an alpha channel

**Code:** `ITMS-90717` · **Category:** iOS · **Seen on:** iOS

The 1024×1024 App Store icon has an alpha channel/transparency, which App Store Connect rejects.

## Meaning

Icons exported from design tools as PNG with alpha (even fully opaque) fail. Re-export without alpha (flatten).

## Common causes

- Icon PNG saved with alpha channel
- Transparent corners/background
- Missing 1024 icon in the asset catalog (ITMS-90704)

## Quick fix

1. Re-export the icon as PNG without alpha
2. Flatten with sips or Preview
3. Ensure the 1024pt icon exists in AppIcon

## Detailed fix by platform

### Shell

1. 

```swift
sips -g hasAlpha AppIcon-1024.png
sips -s format jpeg AppIcon-1024.png --out tmp.jpg && sips -s format png tmp.jpg --out AppIcon-1024.png
```


## How to diagnose

1. **Alpha** — sips -g hasAlpha
2. **Catalog** — 1024 slot filled?
