title: Facebook FBSDKLoginManager/logInWithReadPermissions Swift Example not using Parse
body: <p>Where is the latest Facebook Swift Documentation.  I can't get the FB Login Dialog to show up.  The call to loginWithReadPermissions never returns?</p>
  
  <pre><code>import UIKit
  import FBSDKCoreKit
  import FBSDKLoginKit
  
  
  class ViewController: UIViewController {override func viewDidLoad() {
              super.viewDidLoad()
              // Do any additional setup after loading the view, typically from a nib.
  
              let loginManager = FBSDKLoginManager()
              loginManager.logInWithReadPermissions(["basic_info", "email", "user_likes"], fromViewController: self.parentViewController, handler: { (result, error) -&gt; Void in
                  if error != nil {
                      print(FBSDKAccessToken.currentAccessToken())
                  } else if result.isCancelled {
                      print("Cancelled")
                  } else {
                      print("LoggedIn")
                  }
              })
          }
