IOS simulator won't run the Fun Facts app

When I hit run Xcode brings me to the debug navigator and i see this import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?


    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.
        return true
    }

with the class section highlighted saying "thread 1: signal SIGABRT"

That was the problem! I deleted a button or label, had to start from scratch with them. Worked perfectly after that. After a bit of searching, this forum and google helped me resolve the issue. Thanks!

Glad you got it sorted! A good dig about often leads you to the fix. I hadn't realised my first answer on this thread was 3 months ago!

Shout if you need a help with anything else. You can @ mention me if you want a speedy response!

That error is being thrown from somewhere else. The debugger should produce more than that - can you post all the error messages?

This is most likely caused by the Storyboard not being linked properly. Did you create an Outlet or a button connection, then delete it and try again? That throws this error - it is easily fixed, though.

Look on the left side of the code, on the line were the error is; if there is a fat, blue arrow, right click it and select 'delete breakpoint'.

Wha if there is a small, red arrow instead?

Small red arrows usually indicate that there's a syntax error in your code. Hover over it, or click on it, to see what the error is saying. That should give you some idea how to fix it!

There is nothing showing up when I hover, click, or right click. The only information given is all the way to the right where it says Thread 1: signal SIGABRT

Sorry, I misunderstood.

Have you checked your storyboard for orphan outlets? If you've done the drag/drop more than once or deleted a button, you may have left one behind that's not linking to code properly.
