Swift presentViewController

Question

I programatically have multiple View Controllers in an iOS Swift Project. I do not have the storyboards and would like to avoid them if possible. Is there a way to switch to

Answer 1

You can use code:

if let vc = self.storyboard?.instantiateViewController(withIdentifier: "secondViewController") as? secondViewController {
   let appDelegate = UIApplication.shared.delegate as! AppDelegate
   appDelegate.window?.rootViewController = vc
}
