title: View is loaded from nib but is not visible?
body: <p>I create two custom views using nib files and I create one instance for each class and then I added the two views to my main view , the first view is added and the second is loaded but not visible.</p>
  
  <p>I load the views from the nib file using the following class method </p>
  
  <pre><code>class func instanceFromNib() -&gt; CustomView {
      let view = NSBundle.mainBundle().loadNibNamed("CustomView", owner: self, options: nil).first as! CustomView
      return view
  }
  </code></pre>
  
  <p>I need help to figure out what is going wrong with the second view.</p>
