EXC_BAD_INSTRUCTION when i set UILabel title in Swift 2.0

Question

I want to change the title of an UILabel, but I receive an EXC_BAD_INSTRUCTION error.
My label was correctly connected to the storyboard and I don't understand why i have an error. Could anybody please point where I am wrong? Thank you for your help.

There is my code :

class ViewController: UIViewController {
    @IBOutlet weak var numberLabel: UILabel!
    override func viewDidLoad() {
        super.viewDidLoad()
        self.numberLabel.text = "qwerty" // Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP,subcode0x0)
    }
}

Sorry, in my code, it's not self.label, but it's self.numberLabel — RemyDCF, Sep 12 '15 at 09:57
^^so you really should copy&paste real code that has a problem, and not re-write it. if you re-write your program, it will probably just work ;) — Michael, Sep 12 '15 at 10:02
Sometimes the connections between IB and code can get broken (e.g. when you rename stuff). Have you tried deleting the outlet reference in IB and then readding it? — hennes, Sep 12 '15 at 11:05
I have tried to delete and readding, but I have the same error. — RemyDCF, Sep 12 '15 at 17:00

the problem can be localization. Check if you have 2 storyboards created (one base for english and second for other languages). Then check if in both you have the same label. If not it can be a problem.

Ok, I resolved my problem.
Strangely, if I reinstall Xcode, It's work.
Thanks for your answers.

You should write self.numberLabel.text = "Your text" instead of self.label.text = "Your text" because you have outlet named numberLabel not label .
