As others have mentioned, I think the best way to accomplish this is to have a flag in didFinishLaunchingWithOptions in the application delegate that checks if it is the first launch or not. If the app is being launched for the first time, you can call [[UIApplication sharedApplication] cancelAllLocalNotifications]; This will cancel any existing notifications. … Read more
I would like to add something, since I’ve opened a TSI and somehow I asked about this and have been answered. From Quinn “The Eskimo!”: “This depends on you mean. You have some control over how the notification appears based on how you set the UILocalNotification properties (things like alertBody, soundName, and so on). However, … Read more
If I want a view controller to be notified when the app is brought back to the foreground, I might just register for the UIApplication.willEnterForegroundNotification notification (bypassing the app delegate method entirely): class ViewController: UIViewController { private var observer: NSObjectProtocol? override func viewDidLoad() { super.viewDidLoad() observer = NotificationCenter.default.addObserver(forName: UIApplication.willEnterForegroundNotification, object: nil, queue: .main) { [unowned … Read more

To check remote notifications status in iOS8 you can call [[UIApplication sharedApplication] isRegisteredForRemoteNotifications]; it will return NO if user disable notifications in Settings.

No need to check variables etc when the app resumes from the background. On iOS7 and lower you handle the notifications like this: – (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification { if … Read more
Yes, you can use UILocalNotification, old APIs also works fine with iOS 10, but we had better use the APIs in the User Notifications framework instead. There are also some new features, you can only use with iOS 10 User Notifications framework. This also happens to Remote Notification, for more information: Here. New Features: Now … Read more
There is a delegate method to display the notification when the app is open in iOS 10. You have to implement this in order to get the rich notifications working when the app is open. extension ViewController: UNUserNotificationCenterDelegate { //for displaying notification when app is in foreground func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler … Read more
Solution That Works On Xcode 14 (and lower) Here is one potential solution (thanks to blog post). The idea is to use a stored property with a type of Any and then create a computed property that will cast the stored property (and instantiate it if necessary). private var _selectionFeedbackGenerator: Any? = nil @available(iOS 10.0, … Read more
