TableView returns nil when I try to reload it in a closure in another view controller. My aim is to update the tableView instantly when the data is changed. I have a a static object in HomeVC: static data: MyType = [] { ... didSet {  let storyboard = UIStoryboard(name: "Main", bundle: nil)       let logsVC = storyboard.instantiateViewController(identifier: "LogsView") as? LogsViewController logsVC?.updateUI(with: HomeViewController.data) } } And a func to update tableview in DetailVC:  func updateUI(with data: [MyType]) {           self.tableView.reloadData() // this gives nil error on runtime.    }
