title: Getting "Thread 1:EXC_BAD_ACCESS" error?
body: <p>I am creating a simple web viewer using WKWebView and the Swift language. Here is my code.</p>
  
  <pre><code>import Cocoa
  import WebKit
  
  @NSApplicationMain class AppDelegate: NSObject, NSApplicationDelegate {
  
      @IBOutlet var containerView : NSView! = nil
      @IBOutlet weak var window: NSWindow!
  
  
      func applicationDidFinishLaunching(aNotification: NSNotification) {
          // Insert code here to initialize your application
          var webView: WKWebView
  
          webView = WKWebView() //Thread 1:EXC_BAD_ACCESS (code=1,address=0x20)
          var url = NSURL(string:"http://www.google.com/")
          var req = NSURLRequest(URL: url!)
          webView.loadRequest(req)
      }
  
      func applicationWillTerminate(aNotification: NSNotification) {
          // Insert code here to tear down your application
      }
  
  }
  </code></pre>
  
  <p>I'm now getting a "Thread 1:EXC_BAD_ACCESS" error on the <code>webView = WKWebView()</code> line when I try to run the application. How can I fix this?</p>
