Строка, в которой ошибка:
self.passwordField.delegate = self
Код с кнопки:
@IBAction func unwindToRed(_ sender: Any) {
do {
try Auth.auth().signOut()
let ViewController1 = ViewController()
let ViewNavigationController = UINavigationController(rootViewController: ViewController1)
self.present(ViewNavigationController, animated: true, completion: nil)
} catch let err {
print(err)
}
}
