In this Core Data with SwiftUI tutorial, you’ll refactor an app to add persistence and prevent the nightmare of losing your data when the app restarts.

Array is data structure which stores fixed number of similar elements.Array can store primitive data types as well as object bu it should be of same kind. The Instructor and Course entities have that kind of many-to-many relationship, and your next step is to create an entity class to function as a join table without payload. Removing relationships.
