title: In Swift, how to remove a UIView from memory completely?
body: <p>Please considering following code:</p>
  
  <pre><code>class myManager {
      var aView: UIView!
  
      func createView() {
          aView = UIView()
      }
  
      func removeView() {
          aView = nil // anything else?
      }
  }
  </code></pre>
  
  <p>If I create a <code>UIView</code> like this and later I want to remove it, is this the correct way? Anything I should be aware of? </p>
