Move from one controller to another with segue and story boards

I have finished the first tutorial in the apple developer tool resources where you make an input, label and button what I want is to make it so when you press the button it takes you to a new scene so i have set up the segue, and i'd it as "testPush" now how do i actually get it to move when i push the button i get an error saying

**Thread 1: signal SIGABRT**

And the code that it is replying to is this

return UIApplicationMain(argc, argv, nil, NSStringFromClass([HelloWorldAppDelegate class]));

Anyone got any idea's i know u need to add in code for the segue to work however everything i have seen doesn't make sense or its jsut a block of code with little to none instruction on what it means how u get it to work etc. Thanks for any and all help

Other stuff you might need i'm not to sure Scene one is called: HelloWorldViewController Scene two is called: HelloWorldViewController2

EDIT

Heres the code from my scripts encase you need that thanks. HelloWorldViewController.m

    #import "HelloWorldViewController.h"
    @interface HelloWorldViewController ()
    @property (weak, nonatomic) IBOutlet UITextField *textField;
    @property (weak, nonatomic) IBOutlet UILabel *label;
    - (IBAction)changeGreeting:(id)sender;
    @end
@implementation HelloWorldViewController
- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (IBAction)changeGreeting:(id)sender {

    self.userName = self.textField.text;

    NSString *nameString = self.userName;
    if ([nameString length] == 0) {
        nameString = @"World";
    }
    NSString *greeting = [[NSString alloc] initWithFormat:@"Hello, %@!", nameString];
    self.label.text = greeting;
}

    - (BOOL)textFieldShouldReturn:(UITextField *)theTextField {
        if (theTextField == self.textField) {
            [theTextField resignFirstResponder];
        }
        return YES;
    }

@end

HelloWorldViewController.h

#import <UIKit/UIKit.h>

@interface HelloWorldViewController : UIViewController <UITextFieldDelegate>

@property (copy,nonatomic) NSString *userName;

@end

And main.m

#import <UIKit/UIKit.h>

#import "HelloWorldAppDelegate.h"

int main(int argc, char *argv[])
{
    @autoreleasepool {
        return UIApplicationMain(argc, argv, nil, NSStringFromClass([HelloWorldAppDelegate class]));
    }
}

try adding a performseguewithidentifier in your IBAction, something like the following:

- (IBAction)changeGreeting:(id)sender {

self.userName = self.textField.text;

NSString *nameString = self.userName;
if ([nameString length] == 0) {
    nameString = @"World";
}
NSString *greeting = [[NSString alloc] initWithFormat:@"Hello, %@!", nameString];
self.label.text = greeting;

[self performSegueWithIdentifier:@"segueId" sender:nil];
}

that should push the new for you.
