Swift - Saving highscore using NSUserDefaults

Question

I\'m using Swift to make a game. I want to save the users high score using NSUserDefaults. I know how to create a new NSUserDefaults variable in my AppDelegate file:

Answer 1

var defaults=NSUserDefaults()
var highscore=defaults.integerForKey("highscore")

if(Score>highscore)
{
    defaults.setInteger(Score, forKey: "highscore")
}
var highscoreshow=defaults.integerForKey("highscore")

lblHighScore.text="\(highscoreshow)
println("hhScore reported: \(lblHighScore.text)")
lblPlayScore.text="\(Score)"
println("play reported: \(lblPlayScore.text)")
