How to reload data in a TableView from a different ViewController in Swift

by

Xcode 9 • Swift 4

Create a Notification Name:

extension Notification.Name {
    static let reload = Notification.Name("reload")
}

You can post a notification

NotificationCenter.default.post(name: .reload, object: nil)

And add an observer at the view controller that you want to reload the data:

override func viewDidLoad() {
    super.viewDidLoad()
    NotificationCenter.default.addObserver(self, selector: #selector(reloadTableData), name: .reload, object: nil)
}

@objc func reloadTableData(_ notification: Notification) {
    tableView.reloadData()
}
