What do you mean that your code to ApiEditor was shared privately? Everything about Swagger-UI, Swagger-Editor is open source so I don't understand why you need to share privately.
I think Apigee wanted to announce their own "Swagger Editor" instead of mine when they created the Swagger 2.0 working group with Tony, as is their right since Tony paid me as a consultant, and Apigee put their own employees to work on it. So they made a fresh repo: same name and technology choices, different approach.
