A couple of years ago I made some Xcode 4 project and file templates available to help in creating new projects that use Cocoa-Python, also known as PyObjC.
These templates kind-of, sort-of worked with Xcode 5, but due to changes in how Apple is supporting Python development, required some manual tweaking.
(See https://developer.apple.com/library/mac/technotes/tn2328/_index.html for “Changes To Embedding Python Using Xcode 5.0”)
I’ve updated the templates so they should “just work” with Xcode 5:

Enjoy.
