title: How to divide two numbers in swift using two variables?
body: <p>I don't know what is the problem here. When I divide (in return statement), it gives me "Invalid character in source file".</p>
  
  <p>I tried give some space between 'sum' and 'numbers', but nothing works for me.</p>
  
  <pre><code>func sumOf(numbers:Int...)-&gt;(Int) {
      var sum=0
      for numbers in numbers {
          sum+=numbers
          //
      }
      //println("\(numbers)")
      return sum/numbers
  
  }
  </code></pre>
