Random func playground swift

Question

I am in my playground. I was trying to use the arc4random_uniform func but I get this error: Use of unresolved identifier 'arc4random_uniform'

can I use another func instead?

No it is not a duplicate, His question is specifically for playground. I think that @Kirsteins answer is the good one. — LastMove, Jan 26 '15 at 16:11

Make sure you at least have imported import Foundation. Or platform specific import UIKit for iOS or import Cocoa for OSX.

One of these three should always be in your playground. – David Berry Jan 26 '15 at 16:46

arc4random_uniform is apple platform only (from UIKit). If your playground is hosted on linux, it should not work.

Use rand() or Int/Double/Bool.Int.random()
