ios - 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

Had the same problem, the solution is indeed to use NSNumber in the @NSManaged property. Additionally you could define a computed Bool property so that you can work with the scalar Boolean in your business logic and not with the NSNumber.

var isCompleted: Bool {
get {
    return completed == NSNumber(bool: true)
}
set {
    completed = NSNumber(bool: newValue)
}
}
