title: I get the error: instance member websitetext can not be used on type 'ViewController4
body: <p>I am trying to build a iOS browser app with swift (please keep in mind I am new to swift) and in my code I get the error: instance member websitetext can not be used on type 'ViewController4' This is the only line I get an error with. None of the other forums on this error explain this to someone who is new to swift. Here is my code. Thanks!</p>
  
  <pre><code>import UIKit
  
  class ViewController4: UIViewController, UITextFieldDelegate {
  
      override func viewDidLoad() {
           super.viewDidLoad()
  
          let requestURL = NSURL(string:website)
          let request = NSURLRequest(URL: requestURL!)
           webView.loadRequest(request)
          // Do any additional setup after loading the view.
      }
  
      let website = (string:websitetext.text)  //"https://google.com" line error: Instance member websitetext can not be used on type 'ViewController4
  
      @IBOutlet weak var webView: UIWebView!
      @IBOutlet weak var websitetext: UITextField!
  
      @IBAction func back(sender: AnyObject) {
          if webView.canGoBack {
              webView.goBack()
          }
      }
  
      @IBAction func gohome(sender: AnyObject) {
          self.performSegueWithIdentifier("webtohome", sender: self)
      }
  
      override func didReceiveMemoryWarning() {
          super.didReceiveMemoryWarning()
          // Dispose of any resources that can be recreated.
      }
  }
  </code></pre>
