Swift IF STATEMENT doesn't work in Xcode...What's wrong ?

!import UIKit

class ViewController: UIViewController { @IBOutlet weak var labelSign: UILabel! @IBOutlet weak var nameEnter: UITextField!

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

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

@IBAction func startButton(sender: AnyObject) {
    if nameEnter.text == "China" {
        labelSign.text == "A republic"
    } else {
        labelSign.text == "don't know"
    }

}

}

The thing I want to do is when I type "China" in the textfield and press "start" the information label will change to "A republic". Are there any problems with my code?

Inside the if statement you used the double equal sign instead of a single one, so you compared labelSign.text to a string and you didn't assign a value to it

Try to change from this

 if nameEnter.text == "China" {
        labelSign.text == "A republic"
    } else {
        labelSign.text == "don't know"
    }
 }

to this:

 if nameEnter.text == "China" {
        labelSign.text = "A republic"
    } else {
        labelSign.text = "don't know"
    }
 }
