Xcode 11 doesn't recognize Core data Entity

问题

I just declared an entity called "Users" array:

var UsersArray = [Users]()

I got this error:

use of unresolved identifiers "Users"

hint : I did import CoreData and created the entity

回答1:

Please try this solutions !!

Solution 1 :- Product->Buld for testing solved this issue for me(it solves most unresolved identifier bugs for some strange reason)

Solution 2 :- changing import Foundation to import UIKit. It seems like UIApplication isn't included in Foundation framework.

Solution 3 :- Highlight the Data Model, go to Editor -> Create NSManagedObject Subclass...

Hope this helps thank you..
