View Controller turning up black even though there is content

Question

So when I click on a button from another View Controller, it is suppose to present the next View Controller. However, when clicking the button, it just show the next View Controller with a black screen, even though there is content on it. How do I fix this?

I do know that there had already been similar questions asked but none helped me in solving this issue.

Button clicked code:

@IBAction func onSignUp(_ sender: Any) {
    presentDetail(SignUpViewController())
}

Present next View Controller and animation code:

   extension UIViewController {


        func presentDetail(_ viewControllerToPresent: UIViewController) {
            let transition = CATransition()
            transition.duration = 0.25
            transition.type = CATransitionType.push
            transition.subtype = CATransitionSubtype.fromRight
            self.view.window!.layer.add(transition, forKey: kCATransition)

            self.present(viewControllerToPresent, animated: false)
        }

        func dismissDetail() {
            let transition = CATransition()
            transition.duration = 0.25
            transition.type = CATransitionType.push
            transition.subtype = CATransitionSubtype.fromLeft
            self.view.window!.layer.add(transition, forKey: kCATransition)

            dismiss(animated: false)
        }



}

To clarify, the presentDetail function suppose to present the next View Controller with an animation (From Right), as shown in the code.

You need to instantiate the target ViewController from Storyboard before presenting it.

@IBAction func onSignUp(_ sender: Any) {

presentDetail(

storyboard?.instantiateViewController(withIdentifier: "putyourIdentifierhere"))
}

instantiateViewController function returns the Viewcontroller you want to present.

Doing that results in a black screen still. I put the above code right before presentDetail. And the Storyboard ID is put instead of "putyourIdentifierhere" – Andy Jan 05 '19 at 20:01
Updated my answer. Does your code look like this. Please update your question. – burnsi Jan 05 '19 at 20:05
