Use cases

User Defaults

Just call for example UserDefaults.favouriteRecipes. All user defaults keys are described in UserDefaults.swift.

Core Data

In this case, we have CoreDataManagerProtocol - typealias of another two protocols for working with Step and Recipe managed object models.

public typealias CoreDataManagerProtocol = CDRecipeProtocol & CDStepProtocol

User Defaults

For working with User Defaults, we have implemented 2 property wrappers:

• Usual
• For Codable models

Core Data

For working with Core Data we have implemented Core Data manager - the only place where import CoreData is placed.

It has 2 initializers:

• Usual init
• For unit-tests with NSInMemoryStoreType description for NSPersistentContainer
