title: Cannot divide two NSNumbers in swift?
body: <p>I have two NSNumbers that I want to divide, but in the last line of the code I get the error: "Cannot invoke '/' with an argument list of type '(@Ivalue NSNumber,@Ivalue NSNumber)'"</p>
  
  <pre><code>var firstnumber: NSNumber = object["numberone"] as NSNumber
  var secondnumber: NSNumber = object["numbertwo"] as NSNumber
  var calculated: NSNumber = firstnumber / secondnumber
  </code></pre>
  
  <p>Can anyone help me with this??</p>
