title: UIWebView Produces Blank White Screen
body: <p>I am having trouble resolving an odd issue with my webView.  I am attempting to load a web page (any web page) in a webView which is the sole object within a UIViewController. When I create an instance of the view controller and push it onto the stack, the screen is blank and white.  For now I am attempting to load www.apple.com.  Here is the relevant code:</p>
  
  <p>UIViewController:</p>
  
  <pre><code>import UIKit
  
  class GoodReadsVC: UIViewController {
  
      @IBOutlet weak var webView: UIWebView!
  
      override func viewDidLoad() {
          super.viewDidLoad()
  
          let url = NSURL (string: "http://www.apple.com")
          let requestObj = NSURLRequest(URL: url!)
          webView?.loadRequest(requestObj);
      }
  
      override func didReceiveMemoryWarning() {
          super.didReceiveMemoryWarning()
          // Dispose of any resources that can be recreated.
      }
  
  }
  </code></pre>
  
  <p>For what it is worth, I know that the webView is indeed connected to the xib, due to the little dot being filled in the left margin.</p>
  
  <p>Pushing the controller onto the nav stack:</p>
  
  <pre><code>override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
  
          let bookWebView = GoodReadsVC(nibName: "GoodReadsVC", bundle: NSBundle.mainBundle())
          self.navigationController!.pushViewController(bookWebView, animated: true)
  
  
          tableView.reloadData()
  }
  </code></pre>
  
  <p>What am I doing wrong?</p>
