[RubyMotion] Error building with CoreData support

[willrax]

Hi,

I'm trying to use NSRails with CoreData in a RubyMotion application but it doesn't seem to be able to build properly. Hopefully you can help shed some light. Any help would be great.

Here's my Pod listing:

  app.pods do
    pod "AFNetworking"
    pod "JGProgressHUD"
    pod "JMImageCache"
    pod "FontasticIcons"
    pod "NSRails/CoreData"
  end

and here's the error I'm getting when trying to compile the application.

Hm, interesting. I assume it's been working for you previously and this just came up? My RubyMotion license is expired so it'll be difficult for me to investigate, but in the meantime you can try building against NSRails 2.1.2.

[willrax]

This was the first time i've tried to use or compile NSRails. I'll give the previous version a go tonight and post back here.
