Should I check the “Use scalar properties for primitive data types” when generating a new NSManagedObject subclass from my model file?

I created a project using Core Data, and in the .model file I created an entity called Targets.

I added these two entity attributes:

content (String)
targetID (Integer 32)

When I generate the NSManagedObject subclass Xcode asks me:

Use scalar properties for primitive data types?

Should I check this box when generating a new NSManagedObject subclass from my model file?

If checking the option, the default value for Number type what you get will be zero, but nil is more reasonable. So, I don't think you should check the box.

If the box is checked, Xcode will generate scalar types (e.g., int, float, double) for those attributes. If not checked, the attributes will be NSNumbers.
