Not working with Xcode 6.0.1

I haven't worked out why yet, but straight out of git this is no longer working with Xcode 6.0.1. Any thoughts on what might have changed?

I am trying to add a Haskell syntax highlighting and faced a similar problem. I noticed another project:
https://github.com/jcbnlsn/Xcode-Corona-Editor

In there Xcode 6 update commit, they add:

rm -f /private/var/folders/*/*/*/com.apple.DeveloperTools/*/Xcode/PlugInCache-Debug.xcplugincache

After executing this command, I got Haskell in Editor > Syntax Coloring. Hope this be helpful.
