How to perform conditional segue

Question

I\'ve created a segue through IB. When buttonA is clicked, a transition to viewB will occur.

In the button click action, I have performSegue(withIdentifier:sender

Answer 1

You have created segue from the UIButton to a viewController that is the reason segue happens before the execution of condition. Instead of that remove that segue from storyboard and create another from your ViewController to DestinationViewController.
