How can i create a segue programatically?

I made a segue in order to pass data. When i click the button, it does the segue. I want to manage it manually with code, for example i want an error alert to be shown, before it moves into the next view controller. I use the code below, but when i tap the button, it presents the next controller right after.

I tried this:

performSegueWithIdentifier("mysegue", sender: nil)

Answer

You can't create a segue programmatically. You can invoke one programmatically however. As Paul says, remove the segue from your button and control-drag a segue from the source view controller to the destination you controller. Give it a unique identifier. Then you can invoke the segue in code with a call to performSegueWithIdentifier
