title: image is complaining fatal error: unexpectedly found nil while unwrapping an Optional value
body: <p>I have a master/detail app, where I need to get the image from the master and put it in the detail</p>
  
  <p>It's complaining on the imageView line although I have a file called Gerbera.png image but it won't show.  Also how do I call the image from the master to the detail page?  </p>
  
  <pre><code>class DetailViewController: UIViewController {
  
  @IBOutlet weak var webView: UIWebView!
  
  @IBOutlet weak var detailDescriptionLabel: UILabel!
  
  @IBOutlet weak var imageView: UIImageView!
  
  @IBOutlet weak var btnCall: UIButton!
  
  func configureView() {
      // Update the user interface for the detail item.
  
  
  
      if let detail: AnyObject = detailItem {
  
          if let myWebview = webView {
  
              let stringRepresentation = MasterViewController.MyVariables.urlString?.joined(separator:"")
  
              print ("urlString", MasterViewController.MyVariables.urlString)
              print ("sR",stringRepresentation)
  
              let url = NSURL(string: stringRepresentation as! String)
              let request = URLRequest(url: url! as URL)
  
              myWebview.scalesPageToFit = true
              myWebview.loadRequest(request)
          }
          imageView.image = UIImage(named:"Gerbera.png")!
