It should be split into SpriteBuilder and XCode. It's almost exactly half.

func didLoadFromCCB() {
NSUserDefaults.standardUserDefaults().addObserver(self, forKeyPath: "highscore", options: .allZeros, context: nil)
updateHighScore()
}

NSKeyValueObserving options has no value ".allZeros" should use NSKeyValueObservingOptions.Old

func didLoadFromCCB() {
NSUserDefaults.standardUserDefaults().addObserver(self, forKeyPath: "highscore", options: NSKeyValueObservingOptions.Old, context: nil)
updateHighScore()
}

It should be split into movement and merging - perhaps titled Movement and Game Logic (or some iteration on game logic) respectively.

Movement is a large conceptual unit which should be tackled by itself. Students will first ask about movement not tied into the game - they need to wrap their head around moving tiles around a grid.

Merging then assumes they have a firm grasp of the movement and they can move onto actual game logic. Below merging exists a lot of game logic, which is why it deserves a more general header.

Part 2 is the first one you see, then part 3, then part 1.

On the website, the header "X. Build your own 2048 with SpriteBuilder and Swift - Part X!" shows up at the beginning of every section.

It should be split into Scoring and Polish.

The scoring includes keeping track of score and local high score storage, which is a conceptual unit.

The latter part involves the final visual touches - a separate conceptual unit.

1.I just copied the code and Xcode showed some issues about "fun setupBackground":
" backgroundTile is immutable"
then i added "as! CCNode" to "let backgroundTile = ..." and fixed it.

2.The function didLoadFromCCB need to be added to Grid.Class instead of Grid.swift or there would be an issue "use of unresolved identifier "setupBackground""
func didLoadFromCCB() {
setupBackground()
}

3.Last, I built the project successful, but it stopped running soon and the output:
