Daniel, I should have asked, but you’re using WOnder, right? I use WOnder and templates that generate a lot of good stuff. Are you generating _<Entity> and <Entity> files?
Assuming you are, you can use some of the convenience methods, like: NSArray<Car> = Car.fetchCars(editingContext, Car.BRAND.in(brands), null); You can do all of this without the templates, but you really need ERXKEY to generate the qualifier for you.
