EXC_BAD_ACCESS error when trying to change Bool property

Question

I'm trying to change a Bool property and am receiving an EXC_BAD_ACCESS error.

I'm using XCode 6 and Swift.

The note property saves fine but the completed property throws the EXC_BAD_ACCESS error

import Foundation
import CoreData

class Task: NSManagedObject
{

    @NSManaged var note: String!
    @NSManaged var completed: Bool

}

Changing out the property routine

    // taskObject is an instance of Task()

    // Set the completed flag
    taskObject.completed = true // EXC_BAD_ACCESS

Answer 1

You can use a swift Bool with an NSManagedObject - no need for the NSNumber nonsense. But you need to make sure that in the core data editor, the class is not empty. Enter your objects' name.
