TilemapKit runs on Apple TV news

TilemapKit is a feature rich tilemap game development framework that natively supports all of Tiled Map Editor’s map types, settings and features. TilemapKit reads and writes TMX files, does all the nitty-gritty math for you, and then offers advanced features such as creating grids for pathfinding, flexible tile animations, normal-mapped lighting support and an optimized, multi-threaded renderer. TilemapKit a source code product compatible with SpriteKit, Cocos2D and custom Objective-C engines, and it will soon be available for Cocos2D-X/C++ engines. Its development is largely user-driven by voting on roadmap items as well as quickly supporting new Tiled/TMX features.
