title: Use of unresolved operator <=
body: <p>I am trying to use Swift 3 for-loops, but I have been unsuccessful. Here is what I have:</p>
  
  <pre><code>for assumedPayRate: Double in (0.25..&lt;=billRate) where assumedPayRate += 0.25 {
  </code></pre>
  
  <p>On the <code>..&lt;=</code> it gives me the error:</p>
  
  <blockquote>
    <p>Use of unresolved operator '..&lt;=' </p>
  </blockquote>
  
  <p>Here is the original Swift 2 version:</p>
  
  <pre><code>for var assumedPayRate:Double = 0.25; assumedPayRate &lt;= billRate; assumedPayRate += 0.25 {
  </code></pre>
  
  <p>How can I fix this error?</p>
