We are happy to announce the release of SpriteBuilder! SpriteBuilder is the first complete game development suite for rapidly developing iOS and Android games with Objective-C and Xcode.
SpriteBuilder is the culmination of years of tireless effort from hundreds of contributors. We have brought together the maintainers of the four of the most popular open source iOS game tools (Cocos2d, Cocos3d, CocosBuilder, and Chipmunk) to create a new, integrated development experience. SpriteBuilder 1.0 also includes the much anticipated v3 release of Cocos2d, the most widely used iOS game engine.
