Passing Data between View Controllers without segue [duplicate]

Answer 1

If you navigate programmatically to your second VC you can set Values like so (3rd line)

let storyBoard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let newViewController = storyBoard.instantiateViewController(withIdentifier: "newViewController") as! NewViewController

newViewController.stringVariable = stringVariable

self.present(newViewController, animated: true, completion: nil)
