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.

Answer 2

I had almost this exactly problem.

Boolean works in Core Data.

The problem I had was in the Core Data Editor under 'CONFIGURATIONS' and 'C' Default. I did not have my entity linked to the correct class.

Answer 3

I'm just considering filing a bug as I have the same issue but if your really want to use Bool still then a workaround is to use this method:

setValue(true, forKey: "completed")

Answer 4

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)
}
}
