Swift physicsbody edge recognition issue

Question

The following code recognizes the bottom and top edge of the scene and the ball bounces off as expected. However, the left and right edges of the scene are breached all the time. The ball goes off screen and then eventually returns back if enough force is applied. It is as if the edges of the scene are beyond the edges of the iphone simulator window. Can someone help? Thanks.

import SpriteKit

class GameScene: SKScene {
    override func didMoveToView(view: SKView){
        self.physicsBody = SKPhysicsBody(edgeLoopFromRect: self.frame)
        backgroundColor = UIColor.cyanColor()
        var ball = SKSpriteNode(imageNamed: "ball")
        ball.position = CGPoint(x: self.size.width/2, y: self.size.height/2)
        self.addChild(ball)
        ball.physicsBody = SKPhysicsBody(circleOfRadius: ball.frame.size.height/2)
        let push = CGVectorMake(10, 10)
        ball.physicsBody.applyImpulse(push)

    }
}

You can try to change self.physicsBody size for example;

self.physicsBody = SKPhysicsBody(edgeLoopFromRect: CGRectMake(self.frame.origin.x, self.frame.origin.y, self.size.width, self.size.height))

and change the parameter self.size.width as you wish

I tried changing self.size.width after pasting your code but it does not seem to make any difference – user3865727 Jul 23 '14 at 23:39
@user3865727 do you have this problem for both portrait and landscape mode? I am trying to understand where the problem is coming from – Ahmet Hayrullahoglu Jul 24 '14 at 06:44
Right now the problem is in portrait mode. I have not checked the landscape mode yet. – user3865727 Jul 25 '14 at 04:55
great, we are getting closer to source of problem – Ahmet Hayrullahoglu Jul 25 '14 at 07:29
