Swift : Core Data Integers displaying weird values

http://stackoverflow.com/questions/31801058/swift-core-data-integer-weird-values

Just started learning Swift and have a question around Core Data. I have a very simple entity named "Score" with one attribute "points" which is of type Int16.

Here's my data model class:

class Score: NSManagedObject {
    @NSManaged var points: Int
}

Here's the code on my View Controller:

override func viewDidLoad() {
super.viewDidLoad()

let entity = NSEntityDescription.entityForName("Score", inManagedObjectContext:managedObjectContext!)
let score = Score(entity: entity!, insertIntoManagedObjectContext: managedObjectContext)

println(score.points)
}

What prints in the console is this number: -5764607523034234879

I don't understand what I'm doing wrong. I looked elsewhere and perhaps I need to do something with NSNumber, but I'm unfamiliar with that class.

Shouldn't score.points be empty right now?
