Note: This repository contains the core code of the xcode asset catalog generator framework. If you want to use the generator in a game project, visit the main Xcode Asset Catalog Generator repository.

xc assetcat gen is a batch processing framework that builds the asset catalog from source assets and generates images with optimized sizes for iPad, iPhone, AppleTV and Mac.

• Creates sizes in @1x, @2x and @3x per device type.
• Saves the output directly to the asset catalog in Xcode.
• Handles numbered image sequences.
• Handles Sprite Atlas generation.
• Handles vector images as Universal, Single Scale. PDF and SVG (Xcode 12+).
• Specifically targets game development with SpriteKit.
• Tracks converted images so on each re-generation only new or updated source images are generated to the asset catalog.
• In early development, available as-is. The same goes for the documentation.

I've developed the tool for personal usage, so everything is subject to change between versions and it does have quite a few rough edges.

The wiki has more detailed documentation of how to configure and use the tool.
