I hope you guys can use it and sorry for not defining the variables that were necessary for this question. Again I hope you guys can solve this.

var score = 0
var randomAmountOfTime = Double(arc4random_uniform(5) + 2)
var randomAmountOfTime2 = Double(arc4random_uniform(5) + 2)
var randomAmountOfTime3 = Double(arc4random_uniform(5) + 2)
var randomAmountOfTime4 = Double(arc4random_uniform(5) + 2)
var randomAmountOfTime5 = Double(arc4random_uniform(5) + 2)
