The CoreStoreObject is an abstract class for creating CoreStore-managed objects that are more type-safe and more convenient than NSManagedObject subclasses. The model entities for CoreStoreObject subclasses are inferred from the Swift declaration themselves; no .xcdatamodeld files are needed. To declare persisted attributes and relationships for the CoreStoreObject subclass, declare properties of type Value.Required<T>, Value.Optional<T> for values, or Relationship.ToOne<T>, Relationship.ToManyOrdered<T>, Relationship.ToManyUnordered<T> for relationships.

class Animal: CoreStoreObject {
    let species = Value.Required<String>("species", initial: "")
    let nickname = Value.Optional<String>("nickname")
    let master = Relationship.ToOne<Person>("master")
}

class Person: CoreStoreObject {
    let name = Value.Required<String>("name", initial: "")
    let pet = Relationship.ToOne<Animal>("pet", inverse: { $0.master })
}

CoreStoreObject entities for a model version should be added to CoreStoreSchema instance.

CoreStoreDefaults.dataStack = DataStack(
    CoreStoreSchema(
        modelVersion: "V1",
        entities: [
            Entity<Animal>("Animal"),
            Entity<Person>("Person")
        ]
    )
)
