Swift 4

UI

In my app I show a user's Facebook ID as a button:

@IBAction func messengerButton(_ sender: UIButton) {
    if let id = sender.titleLabel?.text {
        if let url = URL(string: "fb-messenger://user-thread/\(id)") {

            // Attempt to open in Messenger App first
            UIApplication.shared.open(url, options: [:], completionHandler: {
                (success) in

                if success == false {
                    // Messenger is not installed. Open in browser instead.
                    let url = URL(string: "https://m.me/\(id)")
                    if UIApplication.shared.canOpenURL(url!) {
                        UIApplication.shared.open(url!)
                    }
                }
            })
        }
    }
}
