Swift - Boolean property of SKSpritenode - is removed from parent?

Is there a property of an SKSpriteNode which can be used to tell if it has been removed from the parent?

For example,

self.addChild(sprite)
print(sprite.isRemoved) //prints false

sprite.removeFromParent()
print(sprite.isRemoved) //prints true

You check write your function or variable like this using guard statement.

var isRemoved: Bool {
  guard let parent = sprite.parent else {return true}
  return false
}

And you can check this isRemoved variable in your code whether it has been removed from the parent or not.

All SKNode's have a parent property which is an optional. So you can see if the node has a parent. 

if sprite.parent == nil {

}

You can check whether the parent attribute of the SKNode is nil.

if sprite.parent == nil {
    print("sprite has been removed from the parent")
}
