Can't find syntax error.

I am trying hard to find the error. Here's the code I have so far:

#import "AppDelegate.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Customize the nav bar
    UIImage *backgroundImage = [UIImage imageNamed:@"navBarBackground"];
    [[UINavigationBar appearance] setBarTintColor:[UIColor redColor]];
    [[UINavigationBar appearance] setBackgroundImage:backgroundImage forBarMetrics:UIBarMetricsDefault];
    [[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];

    // Customize the tab bar
    NSDictionary *titleTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor], UITextAttributeTextColor, nil];

    [[UITabBarItem appearance] setTitleTextAttributes:[titleTextAttributes forState:UIControlStateNormal]];
    return YES;
}

@end

Sometimes I think that these challenges are unnecessarily difficult, we would be able to spot those errors easily in Xcode... Anyways, hope somebody can help :)

You have a few to much of these "[]". Try this instead:

    [[UITabBarItem appearance] setTitleTextAttributes:titleTextAttributes forState:UIControlStateNormal];

A good tip for these challenges is to actually type them out in xcode, then copy/paste it in

I think you need to remove the "forState" part in the setTitleTextAttribute statement.
