UberJump Tutorial SpriteKit error - ios

Question

I'm using Ray Wenderlich's tutorial called UberJump (https://www.raywenderlich.com/87232/make-game-like-mega-jump-sprite-kit-swift-part-2) and I've run into a logic error. The code used to remove objects is not working and I can't figure out why. I downloaded his source code and his code is not working either.
Here is what I'm having trouble with:
override func update(currentTime: NSTimeInterval) {
//new max height?
//1
if Int(player.position.y) > maxPlayerY {
//2
GameState.sharedInstance.score += Int(player.position.y) - maxPlayerY!
//3
maxPlayerY = Int(player.position.y)
//4
lblScore.text = String(format: "%d", GameState.sharedInstance.score)
}
// Remove game objects that have passed by
foregroundNode.enumerateChildNodesWithName("NODE_PLATFORM", usingBlock: {
(node, stop) in
let platform = node as! PlatformNode
platform.checkNodeRemoval(self.player.position.y)
})
foregroundNode.enumerateChildNodesWithName("NODE_STAR", usingBlock: {
(node, stop) in
let star = node as! StarNode
star.checkNodeRemoval(self.player.position.y)
})
//calculate player y offset
if player.position.y > 200.0 {
backgroundNode.position = CGPoint(x: 0.0, y: -((player.position.y - 200.0)/10))
midgroundNode.position = CGPoint(x: 0.0, y: -((player.position.y - 200.0)/4))
foregroundNode.position = CGPoint(x: 0.0, y: -(player.position.y-200.0))
}
}
The "remove game objects that have passed by" code is not working. It is supposed to remove the platforms as the character jumps on them. Did I write the code out wrong? Thanks.
EDIT: Here is the checkNodeRemovalFunction as well.
class GameObjectNode: SKNode {
func collisionWithPlayer(player: SKNode) -> Bool {
// Award score
return false
}
func checkNodeRemoval(playerY: CGFloat) {
if playerY > self.position.y + 300.0 {
self.removeFromParent()
}
}

It seems like there could be an issue with your checkNodeRemoval function depending on how you're inheriting from the GameObjectNode. Something you could try is taking the checkNodeRemoval function out and checking directly in your update method.
// Remove game objects that have passed by
foregroundNode.enumerateChildNodesWithName("NODE_PLATFORM", usingBlock: {
(node, stop) in
print("found platform node")
if self.player.position.y > node.position.y + 300.0 {
print("attempt to remove platform")
platform.removeFromParent()
}
})
foregroundNode.enumerateChildNodesWithName("NODE_STAR", usingBlock: {
(node, stop) in
print("found star node")
if self.player.position.y > node.position.y + 300.0 {
print("attempt to remove star")
star.removeFromParent()
}
})
