perform segue with identifier wont work in swift 2

Question

I have been using this code to perform a custom segue when a user logs in to the application:

dispatch_async(dispatch_get_main_queue()){

                self.performSegueWithIdentifier("showSTPS", sender: self)

}

I currently have this code in my perpareForSegue (im not totally sure if i need it)

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?){
            if "showSTPS" == segue.identifier {
                }
}

And I am getting the following error every time I try to perform the segue:

2015-08-31 11:56:28.998 ICEFLO[3858:651041] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not perform segue with identifier 'showSTPS'. A segue must either have a performHandler or it must override -perform.'

Any suggestions on what to do would be greatly appreciated - please note that this is for swift2/ios9

Answer 1

Make sure that in your storyboard the segue type is not set to custom. If you set it to custom you'll need to provide your own custom segue class.

Answer 2

Swift version:

class CustomSegue: UIStoryboardSegue {
    override func perform() {

        let src = self.sourceViewController
        let dst = self.destinationViewController
        src.navigationController?.pushViewController(dst, animated: true)
    }
}
