Works on Xcode but not here. Help!

Question: Even though Xcode will generate the code for IBOutlets automatically, it's good to be familiar with the syntax. In the editor below, you have a UIViewController subclass.

Your task is to add an IBOutlet stored property to the class named textLabel of type UILabel. Remember that IBOutlets are generated with an exclamation mark at the end.

My code: 

class ViewController: UIViewController {

    @IBOutlet weak var textLabel: UILable!

    override func viewDidLoad() {
        // Do any additional setup after loading the view, typically from a nib.
    }

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

}

I'm wrong because I'm not adding it to a class named textLabel? But I can't find it or do I have to create one?

Ahhh, It was just a typo Farhan. Try this way 

import UIKit
class ViewController: UIViewController {

    @IBOutlet weak var totalLabel: UILabel!  // I replaced 'UILable' for 'UILabel'

    override func viewDidLoad() {
        // Do any additional setup after loading the view, typically from a nib.
    }

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

Thank you I realized my mistake, and it should be textLabel not totalLabel :)

Hey Farhan,

Have you added: import UIKit on top of the class? UILable is part of UIKit framework so in order to use it you have to import UIKit.

import UIKit
class ViewController: UIViewController {

    @IBOutlet weak var textLabel: UILable!

    override func viewDidLoad() {
        // Do any additional setup after loading the view, typically from a nib.
    }

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

I added import UIKit but it still doesn't work :/. Not sure what to do now. Maybe is it because of the placement of the IBOutlet?
