Enumerations

All errors thrown from CoreStore are expressed in CoreStoreError enum values.

The MigrationType specifies the type of migration required for a store.

The SelectTerm is passed to the Select clause to indicate the attributes/aggregate keys to be queried.

Global utilities

The NSError error codes for CoreStoreErrorDomain.

The LogLevel indicates the severity of a log message.

The containing type for value properties. Use the DynamicObject.Value typealias instead for shorter syntax.

class Animal: CoreStoreObject {
    let species = Value.Required<String>("species", initial: "")
    let nickname = Value.Optional<String>("nickname")
    let color = Transformable.Optional<UIColor>("color")
}

The containing type for transformable properties. Use the DynamicObject.Transformable typealias instead for shorter syntax.

class Animal: CoreStoreObject {
    let species = Value.Required<String>("species", initial: "")
    let nickname = Value.Optional<String>("nickname")
    let color = Transformable.Optional<UIColor>("color")
}

The containing type for relationships. Use the DynamicObject.Relationship typealias instead for shorter syntax.

class Dog: CoreStoreObject {
    let master = Relationship.ToOne<Person>("master")
}
class Person: CoreStoreObject {
    let pets = Relationship.ToManyUnordered<Dog>("pets", inverse: { $0.master })
}

The containing type for value properties. Use the Field typealias instead for shorter syntax.

class Pet: CoreStoreObject {

    @Field.Stored("species")
    var species = ""

    @Field.Stored("nickname")
    var nickname: String?

    @Field.Coded("color", coder: FieldCoders.Plist.self)
    var eyeColor: UIColor?

    @Field.Relationship("owner", inverse: \.$pets)
    var owner: Person?

    @Field.Relationship("children")
    var children: Array<Pet>

    @Field.Relationship("parents", inverse: \.$children)
    var parents: Set<Pet>
}
