Let’s say your two view controllers are named as follows: Master/entry point: ViewController (vcA) Secondary view: ViewControllerB (vcB) You set up the segue from (vcA) -> (vcB) as you have … Read more
Set values from Any ViewController to a Second One using segues Like this: override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { if(segue.identifier == “yourIdentifierInStoryboard”) { let yourNextViewController = (segue.destinationViewController as yourNextViewControllerClass) yourNextViewController.value = yourValue And in your yourNextViewController class. class yourNextViewControllerClass { var value:Int! // or whatever You can call this also programmatically: self.performSegueWithIdentifier(“yourIdentifierInStoryboard”, sender: self) … Read more

Make this method return YES if you want to perform the segue, or NO if you don’t. If your deployment target is earlier than iOS 6.0 You will need to change the way your … Read more
