title: Removing "Optional" in Swift 4
body: <p>That's my code</p>
  
  <pre><code>let temperature = String(describing: Int(incomeTemp.text!))
  
  celcjuszScore.text = "\(temperature)"
  print(temperature)
  </code></pre>
  
  <p>Whent I am pushing a button, the result of print is "Optional(32)" (When I am writing 32 in incomeTemp). I would like to have "Optional" removed and only "32" should stay.</p>
