ValueContainer

public enum ValueContainer<O> where O : CoreStoreObject

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")
}

Required

  • The containing type for required value properties. Any type that conforms to ImportableAttributeType are supported.

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

    Important

    Value.Required properties are required to be stored properties. Computed properties will be ignored, including lazy and weak properties.
