title: Binary operator '+' cannot be applied to operands of type 'DispatchTime' and 'Int32'
body: <p>I'm trying to set a variable time delay for a timer in Swift4, but when I put in the variable I get the error:</p>
  
  <pre><code>Binary operator '+' cannot be applied to operands of type 'DispatchTime' and 'Int32'
  </code></pre>
  
  <p>I used the code:</p>
  
  <pre><code>let when = (DispatchTime.now() + (5 * x))
  </code></pre>
  
  <p>The Variable "x" is an Int32</p>
  
  <p>Please help if you know how to fix it.</p>
