title: Concatenate number with string in Swift
body: <p>I need to concatenate a <code>String</code> and <code>Int</code> as below:</p>
  
  <pre><code>let myVariable: Int = 8
  return "first " + myVariable
  </code></pre>
  
  <p>But it does not compile, with the error:</p>
  
  <blockquote>
    <p>Binary operator '+' cannot be applied to operands of type 'String' and 'Int'</p>
