create array of random numbers in swift

Question

I\'m just starting to learn swift. I\'m attempting to create an array of several random numbers, and eventually sort the array. I\'m able to create an array of one random number

Answer 1

Ok, this is copy/paste of a question asked elsewhere, but I think I'll try to remember that one-liner :

var randomArray = map(1...100){_ in arc4random()}

(I love it !)

EDIT

If you need a random number with an upperBound (exclusive), use arc4random_uniform(upperBound)

e.g. : random number between 0 & 99 : arc4random_uniform(100)

Swift 2 update

var randomArray = (1...100).map{_ in arc4random()}
