UpdatePolicy

public enum UpdatePolicy : String, Equatable

    case allowUpdate

  • The first successfully persisted value is kept; any later attempts to persist a new value to the same destination are ignored.

    Declaration

    case keepFirstValue

  • Declaration

    Swift

    public init?(rawValue: String)
