DynamicSchema

public protocol DynamicSchema

DynamicSchema are types that provide NSManagedObjectModel instances for a single model version. CoreStore currently supports the following concrete types:

  • The version string for this model schema.

    Declaration

    Swift

    var modelVersion: ModelVersion { get }

  • Do not call this directly. The NSManagedObjectModel for this schema may be created lazily and using this method directly may affect the integrity of the model.

    Declaration

    Swift

    func rawModel() -> NSManagedObjectModel

DynamicSchema

  • printCoreStoreSchema() Extension method

    Prints the DynamicSchema as their corresponding CoreStoreObject Swift declarations. This is useful for converting current XcodeDataModelSchema-based models into the new CoreStoreSchema framework. Additional adjustments may need to be done to the generated source code; for example: Transformable concrete types need to be provided, as well as default values.

    Important

    After transitioning to the new CoreStoreSchema framework, it is recommended to add the new schema as a new version that the existing versions’ XcodeDataModelSchema can migrate to. It is discouraged to load existing SQLite files created with XcodeDataModelSchema directly into a CoreStoreSchema.

    Declaration

    Swift

    public func printCoreStoreSchema() -> String

    Return Value

    a string that represents the source code for the DynamicSchema as their corresponding CoreStoreObject Swift declarations.
