## What it is
mogenerator is a command-line tool that generates Objective-C and Swift class files from Core Data .xcdatamodel files. It creates two classes per entity: a machine-managed base class kept in sync with the model and a human-editable subclass for custom logic.

## Use cases
- generate Core Data model classes from an xcdatamodel file
- avoid hand-editing generated Core Data subclasses
- keep Core Data entity classes in sync with data model changes
- add custom logic to Core Data entities without losing generated code
- generate Swift and Objective-C classes for Core Data entities

## When to choose
- you use Core Data in an Xcode project and want safe, regenerable entity classes
- you want a two-class pattern separating generated code from custom logic
- you want to automate model-to-code generation in your build process

## When to avoid
- you don't use Core Data or .xcdatamodel files
- you use Swift-only alternatives like code generation built into Xcode
- you need a GUI tool rather than a command-line utility
