Random number in Swift 3

I am having trouble trying to generate a random number in Swift 3 for use in my game. I have looked around online and can't get arc4random to work for me. Can anyone offer any advice?

Hi Mitch,

You can use GameKit framework to generate a random number in Swift as shown in one of the iOS courses here on Treehouse. The upperBound here represents the maximum value up to which you want to generate the random number. Hope this helps :)

import GameKit
let randomNumber = GKRandomSource.sharedRandom().nextInt(upperBound: 5)

Thank you! i had also tried using GameKit framework but looks like the syntax i was using was out of date! This solved my problem, thanks!
