title: For loop in Swift
body: <p>Suddenly the for loop structure I learned at Apple's documentation stopped working, it shows an error: Expected declaration. Can anyone tell me what's the new syntax? </p>
  
  <pre><code>let CirclePoints = 84
  
  var circlePoint = 0
  
  for circlePoint in 0..&lt;CirclePoints {
  
  }
  </code></pre>
  
  <p>This way also didn't work:</p>
  
  <pre><code>for var circlePoint = 0; circlePoint &lt; CirclePoints; circlePoint++ {
  
  }
  </code></pre>
