iOS Icon Fix

Remove alpha channel from iOS app icons to comply with Apple App Store requirements.

When to Use

• Before uploading to App Store Connect / TestFlight
• After regenerating iOS app icons
• When you see error: “Invalid large app icon… can’t be transparent or contain an alpha channel”

Usage

Run the script:

python3 .claude/skills/ios-icon-fix/scripts/remove_alpha.py

Or specify a custom path:

python3 .claude/skills/ios-icon-fix/scripts/remove_alpha.py path/to/AppIcon.appiconset

What It Does

1. Finds all PNG icons in the appiconset directory
2. For each icon with alpha channel:
   • Creates white background
   • Composites the icon onto it
   • Saves without alpha
3. Verifies all icons have no transparency

Requirements

• Python 3
• Pillow: pip install Pillow
