title: Binary operator '<' cannot be applied to two 'Int?' operands
body: <p>Good evening lovely community,<br>
  this is my first post, please have mercy, if I do something wrong. <br>
  I know there are some similar questions here, but I doesn't understand it.<br>
  Maybe I understand, if someone explain it on my code.</p>
  
  <p>// these are my two TextFields and the "finish"-Button.<br></p>
  
  <pre><code>@IBOutlet weak var goalPlayerOne: UITextField!
  @IBOutlet weak var goalPlayerTwo: UITextField!
  @IBOutlet weak var finishedGameButton: UIButton!
  </code></pre>
  
  <p>// here are my function, it should tell me, which Player has won like A &lt; B, so B has won.</p>
  
  <pre><code> @IBAction func finishedGameButtonPressed(_ sender: Any) {
      // define UITextField as Integer
  
  let goalPlayerOne = "";
  let goalOne = Int(goalPlayerOne);
  
  let goalPlayerTwo = "";
  let goalTwo = Int(goalPlayerTwo);
  </code></pre>
  
  <p>// here is the problem: <br>"Binary operator '&lt;' cannot be applied to two 'Int?' operands"<br>
  // if I make a '==' it works</p>
  
  <pre><code>if goalOne &lt; goalTwo{    
      displayMyAlertMessage(userMessage: "Player Two wins")
      return
  }
  </code></pre>
