I have been looking for a data synchronization solution for an iOS app I have been working on for quite some time, and I think I found the solution in the Helios backend framework. The first problem I have noticed is there is little to no documentation covering this project. The only shred of useful information I have discovered is the Readme on the Github project page.
Now I know I need to use Postgres in order to use this framework with my rails app which I have converted too. Next, I understand this framework allows building a standalone app with the helios command. I would prefer to keep my existing rails app that I have spent time building and incorporate helios as a gem in the current project I am working on, which the Readme provides information on. However I would like to know how I would link up xcdatamodel with a standalone rails application because I did not see any documentation on this when reading the Readme. Finally, are there any valuable resources on the internet concerning this framework?
