 **SKTiled** is a framework for using [Tiled][tiled-url] assets with [Apple's SpriteKit][spritekit-url], built from the ground up with Swift. This project began life as an exercise to learn Apple's new programming language for a game project, but I've decided to release it as open source with the hopes that others will find it useful. **SKTiled** is up-to-date and supports **Tiled's** major features, including all map & object types.
