I’m using Core Data with Rubymotion, and I don’t want to use the Xcode graphical data modeller, I’m just creating a bunch of NSEntityDescriptions and NSEntityAttributes in code, and it works great.
But I haven’t figured out if it is possible to use Core Data schema migrations without creating the .xcdatamodeld files?
And also, if it’s not possible to run migrations without .xcdatamodeld files, maybe there are some libs that can generate the required files from NSEntityDescriptions?
Thanks
Take a look at how MotionData is trying to achieve this.

Probably we have to play with NSMigrationManager. See their spec and how it might be able to use it https://github.com/alloy/MotionData/blob/master/spec/schema_spec.rb#L146
Please share us if you are able to figure this out. I am trying to solve the exact same problem too.
