NSUserDefaults - Saving and retrieving "High Scores"

I am just learning to program and doing some SWIFT tutorials. I have done as much research as I could but seem to be missing some critical aspect. I have a simple game and when a player dies I want to check their score against the previously saved high. If it's higher it's to save the new score.

On a title screen the highest score is displayed.

Here is the current code I am using;

NSUserDefaults.standardUserDefaults().integerForKey("highscore")

    if score > NSUserDefaults.standardUserDefaults().integerForKey("highscore") {
        NSUserDefaults.standardUserDefaults().setInteger(score, forKey: "highscore")
        NSUserDefaults.standardUserDefaults().synchronize()
    }

    NSUserDefaults.standardUserDefaults().integerForKey("highscore")

The problem I cannot solve is simply how to print the highscore! I tried using;

hiScoreText.text = "Hi Score :  \(highscore)"

but as I guessed that isn't correct. What variable do I use or how do I "read" the highscore that has been saved?

Any advice for a new guy would be greatly appreciated.

I guess you forgot to save retrieved highs score to the variable:

let highscore = NSUserDefaults.standardUserDefaults().integerForKey("highscore")

You have to store the result of NSUserDefaults.standardUserDefaults().integerForKey("highscore") inside a variable that you print.
