I want to add cocos2D V3.3 to the workspace and my New project will use cocos2D libraries to develop game. In cocos2D V3.1 there was a installer now there is no installer also. so how can i make it..thanks in advance
Cocos2d is not available as a template installer for Xcode anymore. Instead cocos2d is now bundled with an application called spritebuilder which is available in the Mac Appstore.
You could create a new project in spritebuilder and add your source files and resources from your old project. Its now the most preferred way, as it provides you with automatic cocos2d updates.
If you still want to go the old school way, you'll have to get the zip download from cocos2d repo in github and add them to your existing project.
The following link explains how to create a new project using spritebuilder.
