Using Core Data is awesome.
moGenerator makes it even better, as you can have Entitites defined as being of a particular class, and this code generator creates two classes for each Entity - a machine-readable one which is updatable by running the script again, and a human readable one that you can safely edit - it won’t be changed once it has been created.
You can easily make this tool a part of you build process.
First, create a new directory inside your project folder, I called mine MO. Then, cd to that directory, and run:
$ mogenerator -m ../*_DataModel.xcdatamodel
Then add the folder MO to your project.
Now add a new build phase script, and put into it:
mogenerator -m ../*_DataModel.xcdatamodel
It’s not quite perfect - if you add a class, it won’t be added to your project automatically. You might be able to get around this by including the -includem switch, but then you won’t be able to have the .m files located in your project, else you will get duplicate symbol errors.
