title: How to add cocoapods to existing workspace not project
body: <p>I am working on a project which is composed of three other projects in a workspace. I want to use CocoaPods to manage my dependecies in the workspace, but CocoaPods always creates its own workspace with only one addtional project. What I want to do is to add CocoaPods project to the workspace that already exists. Is there any simple way to achive that?</p>
