title: switch statement gone wrong - swift language
body: <p>in Obj-c i made a switch statement which i used to move around in my app for iPad using UIsplitviewcontroller 
  now i want to do the same in swift... i tried for a couple of hours and now the only thing i haven't been able to try is the code because it says some sort of compile error
  anyway
  here's what i got in Obj-c</p>
  
  <pre><code>-(void)initialSite:(int)viewId {
  UIViewController *viewController;
  switch (viewId) {
      case 0:{
          viewController = self.initital;
          NSString *star = [NSString stringWithFormat:@"Velkommen til %@'s  Bog",[data valueForKey:@"navn"]];
          self.navigationItem.title = star;}
          break;
      case 1:{
          viewController = self.startSide;
          NSString *start = [NSString stringWithFormat:@"%@'s  Bog, start-side",[data valueForKey:@"navn"]];
          self.navigationItem.title = start;}
          break;
  }
  [self showChildViewController:viewController];
  
  }
  </code></pre>
  
  <p>and here's what i come up with so far in swift. still new to this and to understand it is a little hard even tho i have the swift programming language book</p>
  
  <p>here's what i got so far in swift</p>
  
  <pre><code>    let viewController = UIViewController()
  switch viewController {
  case "initial":
  let initial : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
  let vc0 : UIViewController = initial.instantiateViewControllerWithIdentifier("initial") as UIViewController
  self.presentViewController(vc0, animated: true, completion: nil)
  let rowData: NSDictionary = self.menuItemArray[indexPath.row] as NSDictionary!
  self.navigation.title = rowData["navn"] as? String
  
  case "startSide":
  let startSide : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
  let vc1 : UIViewController = startSide.instantiateViewControllerWithIdentifier("startSide") as UIViewController
  let rowData: NSDictionary = self.manuItemArray[indexPath.row] as NSDictionary!
  self.presentViewController(vc1, animated: true, completion: nil)
  self.navigation.title = rowData["navn"] as? String
  default:
  
  
  }
  </code></pre>
  
  <p>the error is : <strong><em>Expected declaration</em></strong> at the line with 
      <strong><em>let viewController = UIViewcontroller()</em></strong> </p>
