ViewController Appears to Transition Twice

Question

Problem Summary

My mainVC --> second VC transtion appears to run twice. However, what\'s odd is that the second VC\'s viewDidLoad only runs once. This i

Answer 1

I had ALMOST the same problem and my second VC was sliding twice. The problem was with that segue arrow in my Main.storyboard. I control-dragged from a button in first VC and not from my VC (that little yellow circle on top of every VC), so I deleted that segue arrow and control-dragged from VC yellow circle to my second VC and it fixed the problem.

Also this is how I used performSegue function:

@IBAction func toSignUp(_ sender: Any) {
    performSegue(withIdentifier: "signUp", sender: nil)
}

Hope this was helpful.
