Why are the positions of my nodes different on each device?

Question

Ok, so I tried to position the line on my iPhone 6s + and my iPad 2. The line was added to SKCamera (I don't know if this affects it or not). Here is the code for the line:

    var leftWall = SKSpriteNode()
    leftWall.size = CGSize(width: 1, height: 10000)
    leftWall.position = CGPoint(x: 0, y: 0)
    leftWall.color = UIColor.red
    leftWall.physicsBody = SKPhysicsBody(rectangleOf: CGSize(width: leftWall.size.width, height: leftWall.size.height))
    leftWall.physicsBody?.affectedByGravity = false
    leftWall.physicsBody?.isDynamic = false
    leftWall.physicsBody?.categoryBitMask = groundGroup
    leftWall.physicsBody?.collisionBitMask = ballGroup
    leftWall.physicsBody?.contactTestBitMask = 0
    theCamera.addChild(leftWall)

Okay, so that position x is 0.0 on the right? Here's what it looks like on my iPhone 6s +: As you can see, the line is in the middle?

Here's what it looks like on my iPad 2:

I just don’t understand why the line position is completely different. Please help me!

You do not take into account the framing that occurs on the iPad, or your scaleMode is erroneous.
