You can use NotificationCenter here.

You can register an observer in view in which you want the notification.

NotificationCenter.default.addObserver(self, selector: #selector(appIsActivited), name: NSNotification.Name.UIApplicationDidBecomeActive, object: nil)

When app becomes active then a notification is fired and appIsActivited method will be called.

 @objc func appIsActivited() {
    //do something
}

Note: Don't forgot to remove observer from view once it is no more needed to releases view's occupied memory.
