PrepareForSegue Swift (changing UIImage and UILabel)

So I'm writing the prepareForSegue for my app but having issue setting up the code for changing the UIImage and UILabel for the destination ViewController.

What would be the code to change the images and UILabel when segue to the next ViewController?

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if (segue.identifier == "toTest") {            
        let destViewController : data3ViewController = segue.destinationViewController as data3ViewController    
    }
}

I you have in your data3ViewController an UILabel and an UIImage , let says named myLabel and myImage respectively , then you should do the following :

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
   if (segue.identifier == "toTest") {            
      var destViewController : data3ViewController = segue.destinationViewController as data3ViewController   
      let _ =  destViewController.view
      destViewController.myLabel.text = "Something"
      destViewController.myImage = UIImage(named: "photo")
   }
}

The call above to destViewController.view ensure that the @IBOutlet's are initialized before set it values.

I hope this help you
