Core Data Relationships and SwiftUI

A one to one relationship means that one object in an entity links to exactly one object in another entity. In our example, this would mean that each type of candy has one country of origin, and each country could make only one type of candy.
A one to many relationship means that one object in an entity links to many objects in another entity. In our example, this would mean that one type of candy could have been introduced simultaneously in many countries, but that each country still could only make one type of candy.
A many to one relationship means that many objects in an entity link to one object in another entity. In our example, this would mean that each type of candy has one country of origin, and
