I tried your code and it worked just fine, make sure you are implementing this code in mainViewController.m though

#import "MainViewController.h"
#import "LoginViewController.h"
#import <Parse/Parse.h>

@implementation MainViewController

- (void)viewDidLoad {
    [super viewDidLoad];

   PFUser * currentUser = [PFUser currentUser]; 
   if (currentUser==nil) { 
   [self performSegueWithIdentifier:@"showLogin" sender:self]; 
   }


}

- (IBAction)logOut:(id)sender {

    [self performSegueWithIdentifier:@"showLogin" sender:self];
}

@end
