Any idea? It just says no documentation.

import Foundation

struct Game { var target: Int = Int.random(in: 1...100) var score: Int = 0 var round: Int = 1

func points(sliderValue) -> Int {
let difference = abs(target - sliderValue)

    // or difference*= -1
    // or difference = -difference
    let awardedPoints = 100 - difference
    return awardedPoints
}

}

difference is an int but its not showing up like this
