Here's my solution:

import UIKit

var repeatCounter = 1
var pickedNumbers = [Int]()

repeat {
    
    let rangeValue = Int.random(in: 1...100)
    
    if pickedNumbers.contains(rangeValue) {
        
        print("\(rangeValue) already exists in the array")
    
    } else {

        pickedNumbers.append(rangeValue)
        print([pickedNumbers])
        repeatCounter += 1
    }

} while repeatCounter < 6
