title: Can not pick random number from Array in swift
body: <p>I have this code and I want to pick a random element from Array1 and a random element from Array2 but Xcode is only giving me the number of the element.</p>
  
  <pre><code>let firstNrVar = [0, 2, 4, 6, 8, 10]
  let secondNrVar = [0, 2, 4, 6, 8, 10]
  func numberRandomizer() {
      let shuffledFirstNr = Int(arc4random_uniform(UInt32(firstNrVar.count)))
      firstNrLbl.text = "\(shuffledFirstNr)"
      print(shuffledFirstNr)
      let shuffledSecondNr = Int(arc4random_uniform(UInt32(secondNrVar.count)))
      secondNrLbl.text = "\(shuffledSecondNr)"
      print(shuffledSecondNr)
  }
  </code></pre>
