From .xib to .storyboard:

let sb = UIStoryboard(name: "the-name-of-the-storyboard", bundle: nil)
let ctrl = sb.instantiateViewController(withIdentifier: "SecondViewControllerIdentifier")
self.present(ctrl, animated: true, completion: nil)

Keep in mind that SecondViewControllerIdentifier is the identifier of the storyboard scene; it is not the class name of your controller

From .storyboard to .xib:

let ctrl = FirstViewController()
self.present(ctrl, animated: true, completion: nil)

Assuming that either FirstViewController.xib or First.xib exists

  • That seems to be a problem _within_ your view controller and does not seem to be related to the initial problem. Might be related to this: https://stackoverflow.com/questions/52455652/xcode-10-seems-to-break-com-apple-commcenter-coretelephony-xpc – Andreas Oetjen Feb 18 '20 at 15:10

  • I think you forgot to add sb object, Thank you so much – Mahmudul Hasan Feb 18 '20 at 15:36
  • Yes, just a copy/paste issue :-) – Andreas Oetjen Feb 18 '20 at 22:28
