IBOutlet not connecting in Interface Builder-Xcode 4.2

Question

I read other questions here, but they seem to be for Xcode 3.2 or earlier, but nothing for 4.2 .:(

I started a simple project and wanted to connect the File Owner Outlets outputs in my xib. Bummer that my IBOutlet from my ViewController.h is not suitable.

I don't have a reputation of 10 or higher, so here is a screenshot of my owner of a file not showing my IBOutlets .

Here is my ViewController.h code:

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController { 
    IBOutlet UITextField *txtName; 
    IBOutlet UILabel *lblMessage;
}

@property (nonatomic, retain) IBOutlet UITextField *txtName;
@property (nonatomic, retain) IBOutlet UILabel *lblMessage;

- (IBAction)doSomething;

@end

Here is my ViewController.m code:

#import "ViewController.h"

@implementation ViewController

@synthesize txtName;
@synthesize lblMessage;

- (IBAction) doSomething
{
    NSString *msg = [[NSString alloc] initWithFormat:@"Hello, %@",txtName.text];
    [lblMessage setText:msg];
}

@end

I am new to Objective-C and Xcode, so I could be wrong, but I followed many tutorials and I can never show my IBOutlets. I uninstalled Xcode 4.2 and reinstalled it to fix this problem. Here is a screenshot of my version of Xcode version 4.2, build 4D199 .
