As I read here OS X Server running on OS X Mavericks now supports continuous integration.
The Xcode service supports two popular source control systems: Git and Subversion. You can use Git and Subversion repositories hosted on remote servers, and you can host and use Git repositories on the server running the Xcode service.
I was really confused that Apple ignores Mercurial in this case.
So the questions:
Are there any workarounds how to use Mercurial repository with XCode continious integration?
If NO, are there any else tools to provide continuous integration with Mercurial?
