Navigating One View Controller to Another using Swift 5 doesn't work

Question

Okay guys, now that I have fixed this because of your help,

the error has gone.

but the page won't move to the 'requirementVC', so the button when i clicked, it just doesn't do anything.

@IBAction func buttonOK(_ sender: Any) {

    let button = (self.storyboard?.instantiateViewController(withIdentifier: "RequirementsVC") as! requirementVC)
    self.navigationController?.show(button, sender: nil)

}

Thankyou again, appriciate it!

your button's class is ViewController not a requirementVC, are you sure with identifiers? — Alexandr Kolesnik, Nov 27 '19 at 09:24

Have you set the storyboard controller class name requirementVC? — Faysal Ahmed, Nov 27 '19 at 09:34

You can do the following...

@IBAction func buttonOK(_ sender: Any) {

  let vc = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "RequirementsVC") as! requirementsVC
  self.navigationController?.pushViewController(vc, animated: true)

}

Here Main is the name of the storyboard.

RequirementsVC should be storyboard id set in storyboard.

And requirementsVC should be the subclass of the UIViewController.

//Class name should always start with capital letter. So rename requirementsVC to "RequirementsVC"
class RequirementsVC: UIViewController {

    //class body

}

still having the same error here.. also, i already create the view controller by dragging it. so i already have one. i just want to go from one page to another programmatically – Aldo Sugiarto Nov 27 '19 at 09:28
can you post the code of the `RequirementsVC` class – Mahendra Nov 27 '19 at 09:31
just default code.. import UIKit class requirementVC: UIViewController { override func viewDidLoad() { super.viewDidLoad() } } */ } – Aldo Sugiarto Nov 27 '19 at 09:32
What is the "App"? is it your project name or custom class name? – Mahendra Nov 27 '19 at 09:44
"App" is my project name – Aldo Sugiarto Nov 27 '19 at 09:50

just set your identifier and class of viewController you want to go on in this code :=

    let addReminderVc = self.storyboard?.instantiateViewController(withIdentifier: "AddReminderVC") as! AddReminderVC
    self.navigationController?.pushViewController(addReminderVc, animated: true)

i did everything u said, i've set the storyboard id, set it to asction, & so on, it run fine but the only thing when i click the button, nothing happened. nothing change. – Aldo Sugiarto Nov 28 '19 at 03:30
did you check for getting nil navigation controller by setting break point. so, may be you did not Embed your initial Vc in NavigationController. – viral goti Nov 28 '19 at 05:42
