How do you tell if a node is on the screen spritekit swift

Question

I am trying to figure out how to determine if a node is visible on the screen or off the screen. Is this just a true/false property of the node? Thanks. (Using swift spritek

You can use the following to test if a node is in the scene:

if (!intersectsNode(sprite)) {
  println("node is not in the scene")
}

This assumes that self is an SKScene subclass, such as GameScene.
