iOS Segue not working as expected when passing value

I have a button with the following code:

@IBAction func buttonPress(sender: AnyObject) {
    performSegueWithIdentifier("newAccount", sender: sender)
}

When the button is pressed it performs a segue. I want to pass a value to the new view controller so I added the following code:

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if segue.identifier == "newAccount" {
        if let dvc = segue.destinationViewController as? NewAccountViewController {
            dvc.testValue = "This is my test value I want to pass"
        }
    }
}

The NewAccountViewController doesn't receive the value (I don't get any error).

The code I have in my NewAccountViewController is:

var testValue:String?

When I print(testValue) I don't get anything.

Why isn't this working as expected?

There are maybe two reasons: 1. identifier is not set as "newAccount" in the storyboard; 2. you have put a navigator view controller into the NewAccountViewController, which would ask you to transfer the destination as UINavigationController instead of NewAccountViewController. Hope this helps.

You need to check if the class is set correctly

Like the ViewController in below image
