What do I do with the yellow warning called "thread 1: signal SIGABRT" after running the Fun Facts App?

Is there something wrong with my code here on the last step of making the Fun Facts app? @UIApplicationMain class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?


func application(application: UIApplication!, didFinishLaunchingWithOptions launchOptions: NSDictionary!) -> Bool {

    application.setStatusBarStyle(UIStatusBarStyle.LightContent, animated: false)
    // Override point for customization after application launch.
    return true
}

seeing thread 1: signal SIGABRT usually means you have an uncaught exception being thrown. look in the console. there should be more information about what is causing the exception. can you post what you find in the console (you may have to scroll around some)

select Debug -> Breakpoints -> add exception breakpoint. then run your code. it should break on the line thats throwing the exception. post the code that it breaks on.
