Random number generator

Hi everyone. I would like to ask you. Why we write all this code:

import GameKit

func randomFact() -> String { let randomNumber = GKRandomSource.sharedRandom().nextInt(upperBound: facts.count) return facts[randomNumber] }

if we can just write


without importing anything and writing more code? What is the difference?

Would like to know the same.
