Cant randomize Arrays in Swift with Int.random(in: x...y)

Question

I'm using earlier version of xcode (8.2.1) , I didnt succeed to update xcode from the app store.

any way it doesnt allow me to do randomize me arras elements ( which are cube picture for a roll dice app )

diceImageView.image  = [photo1...to..photo6 [Int.random(in: 0...5)]

the .random after Int just doesn't exist. I dont know what an alternative to use most of the stuff i've seached for they are more advanced or dont work\dont understand it, also tried arc4random_uniform unit32 and shuffle and such but it doesn't work.

can someone explain me how to randomize it?

Instead of `Int.random(in: 0...5)`, you could use `Int(arc4random_uniform(UInt32(6)))` — Reinhard Männer, Dec 09 '19 at 13:41
The duped-answer includes solutions going back to Swift 1.2, so one of them should work for you. Welcome to SO. — Rob Napier, Dec 09 '19 at 18:19

Once you update Xcode you can just use the shuffle method like so array.shuffle(). The shuffle() method randomly reorders the elements of an array by passing in the system's default random generator and is O(n) complexity. I posted a screenshot below.

Please post your code not as a screenshot, but include it properly formatted in your answer. – Kamil.S Dec 09 '19 at 18:15
