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

Question

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?

Answer 1

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.

Answer 2

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.
