Storyboard error regarding boolean and ViewController rooting issue

Question

I have this boolean in my AppDelegate.m:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    {
        self.window = [[UIWindow alloc] initWithFrame:UIScreen.mainScreen.bounds];

        UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];

        UIViewController *viewController = // determine the initial view controller here and instantiate it with [storyboard instantiateViewControllerWithIdentifier:<storyboard id>];

        self.window.rootViewController = viewController;
        [self.window makeKeyAndVisible];

        return YES;
    }

I'm getting an error on the *storyboard but what I am mainly trying to do is initialize the application in a different view controller than the main one. I have all the view controllers with IDs (such as the one I want to launch is named "Home"). How would I correctly write this bool if say my ViewController ID was home?

My main.m:

#import <UIKit/UIKit.h>
#import "AppDelegate.h"

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

The nil I get is whenever I try to go back to the original Home page from my Contact list page so it crashes and highlights the nil line. Both this and the above delegate bool are giving me issues. Any clarification would be very much appreciated, thanks.
