Clojure(Script) library for declarative data description and validation

How to change the name of the active scheme in XCode?

I managed to change my project name, but how do I change the name displayed in this screenshot?

Screenshot showing text directly to the left of "iOS Simulator"

And (please) don't preach me about proof of concepts that should always be rewritten from scratch, this POC was very neat and tidy and I was working to make an impossible deadline :-)
