How do you pass data between view controllers in Swift?

by

One solution would be to override prepareForSegue(segue:sender:) from within the view controller which contains the data that you wish to pass to the destination view controller.

override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {
    if (segue.identifier == "YourSegueName") {
        //get a reference to the destination view controller
        let destinationVC:ViewControllerClass = segue.destinationViewController as! ViewControllerClass

        //set properties on the destination view controller
        destinationVC.name = viewName
        //etc...
    }
}
