Following along, but my app doesn't work!

Here is the code I have in the ViewController Class:

class ViewController: UIViewController {

    @IBOutlet weak var funFactLabelOne: UILabel!
    let facts = ["Fact", "New Fact", "New New Fact"]

    override func viewDidLoad() {
        super.viewDidLoad()
        funFactLabelOne.text = facts[0]
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    @IBAction func showFunFact() {
        funFactLabelOne.text = facts[1]
    }

}

When I run the code in the iPhone simulator, when I click the button, the app crashes and the output section of the debugger says "lldb". I am at a loss.

Hi Nat, new to this also, but I tested a bit and (assuming you hooked up everything properly) your code looks fine.

However, you may have accidentally added a breakpoint. In Xcode hit the keys: command+7. Alternatively, go to the navigator menu (left side of screen) and go to the icon second from the right.

Delete any breakpoints you find there and let me know if that solved the problem. If it didn't you may be having issues with optionals/calling something that doesn't exist. Thanks.

No problem. Just for the future, you add one by clicking the gutter in your source code. I add them accidentally all the time :)

They are useful for debugging though if you don't know where the code is messing up. You can break your program into chunks and see where things are going wrong.

Happy coding.
