Can't add text to a stored property?

I get an error saying 'bad instruction' when trying to run my app from the line of code below: funFactLabel.text = [0]

I receive this error when I try to add any text to the funFactLabel stored property. Any idea why?

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var funFactLabel: UILabel!
    let facts = ["Ants stretch when they wake up in the morning", "Ostritches can run faster than horses"]

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

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }

Hm... tough to diagnose this error without being able to poke around in the code. My first step would be to make sure your @IBOutlet is correctly hooked up to your storyboard. Easiest way to check this is to go into your storyboard, select the label, and open the connections inspector in the right sidebar (the -> icon all the way to the right).

Report back if that was your issue!

The "Show another fun fact" label has Touch Up Inside connected to View Controller showFunFact.

The "Some fact goes here" label has no connections.

Not sure what to make of it. I would probably download the project files Pasan provides, and compare your code to see if there are any discrepancies. Assuming you have a closing curly brace, the code you've pasted here looks fine.
