Xcode-beta 8. Can't create core data

Question

I have been trying to add core data. And every time I got the same error:

error: filename \"EntityName +CoreDataClass.swift\" used twice: \'/Users/userName/         


        

Answer 1

Tom Harrington Answer is correct. However, there is a way to add your own functions and/or vars without doing any of the two mentioned options.

Just create an extension to the class. (make sure you name the swift file something different than the standard auto-generated NSManagesObject files.)

For example. If you have an entity called MyEntity you could add a swift file called MyEntityExtension.swift which could look something like this:

import Foundation
import CoreData
import UIKit


extension MyEntity {

    var color: UIColor {
        get {
            return self.colorValue as! UIColor
        }
        set {
            if newValue.isMember(of: UIColor.self) {
                self.colorValue = newValue
            }
        }
    }

}
