To debug Core Data code in VSCode/Cursor, you only need to do two things:

- use Xcode's Swift toolchain
- after the first time or after adjusting the model, use a script to compile xcdatamodeld into momd and place it in the correct build directory

How does SwiftData convert these code declarations into models that the default storage (Core Data) can recognize when using a purely code-based declaration? Understanding the underlying principles is very helpful for correctly creating models. 👇
