Xcode 4 completely changed the (project) template system. There\'s a lot more you can do now, but it comes at a price. Take a look in the TemplateInfo.plist files scattered
I'd expect that a tool to help developers manage template libraries is something Apple will be releasing at some point but the priority has to be there if you want to see it anytime soon. Be sure to submit a bug report (https://bugreport.apple.com/) so that Apple knows that it is a concern. You could even reference all of the blog posts and forum posts which show the number of developers who want to manage templates with a tool.
