Hi, on my textbook I am using to learn Swift, report a method from the Swift library to generate random numbers. They are in the chapter where the protocols are explained. How come it gives me error on the arc4random method? Thank you 😉
EDIT: sorry , I forgot to post the code, convinced I did: /
// Sanseverino Raffaele
// Random Generator
protocol numeroRandom {
func random()-> Double
}
class Generatore : numeroRandom {
func random() -> Double {
let n = Double(arc4random())
return n
}
}
let num = Generatore()
num.random()
