Hi, we have an application that observes PDFViewVisiblePagesChanged and PDFViewPageChanged notifications for detecting the scroll state of a PDFView NotificationCenter.default.addObserver(self,                                                 selector: #selector(handleOnScroll),                                                name: Notification.Name.PDFViewVisiblePagesChanged,                                                 object: nil) NotificationCenter.default.addObserver(self,                                                 selector: #selector(handleOnScroll),                                                name: Notification.Name.PDFViewPageChanged,                                                 object: nil) With iOS14 this worked like a charm, the notification gets triggered immediately when the user starts scrolling the pdf. In iOS16 we have issues, it seems that the notifications get triggered/send only after the scrolling has been completed/stopped. Can anybody confirm this? Has anybody a solution how we can detect a scrolling PDFView using a different method? Background: While the PDF is scrolling other elements of the UI need to be disabled. Thanks Jürgen

I try to receive remote notifications in widgets(implemented through WidgetKit), but failed. It known that enable remote notifications should register first by calling UIApplication.shared.registerForRemoteNotifications() but in widget cannot calling shared, it is available in widgets @property(class, nonatomic, readonly) UIApplication *sharedApplication NS_EXTENSION_UNAVAILABLE_IOS("Use view controller based solutions where appropriate instead."); and if try to init a UIApplication(by UIApplication()), the app will crash for more than one UIApplication instance.

I have a cli program which does a thing for a while, and I'd like it to post a notification on the screen when it's done. Note that because it's a standalone program, not an app, it doesn't have a bundle, per se. I tried to use UserNotifications, but I get an immediate error with the line let center = UNUserNotificationCenter.current() With the error: Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'bundleProxyForCurrentProcess is nil: mainBundle.bundleURL My entire program to produce this bug: import Foundation import UserNotifications let center = UNUserNotificationCenter.current() print("Hello, World!")

I wish to support Mac with my iPhone/iPad app using Mac Catalyst. Our app shows widgets on iPhone/iPad home screen properly. Using Mac Catalyst is straight forward (except to exclude all ActivityKit codes). However, although the app shows up and work perfectly, I can't see the widgets in notification center. Separate compile the widget extensions show no errors but nothing is shown. Also tried build separately, drag into Applications folder, run the build and the widgets are not shown. Any suggestions? Using the Xcode 14.2 and macOS 13.1.

I'm having a problem in iOS. When popup request notification permission display then I dismiss pop up by button home or navigation bar (Not click to Allow or Don't Allow) => Not display setting Notification in app setting (Status not determined) => request notifications permission again => Popup displayed again. I can not find any doc about this behavior. Is this a change in iOS 16? Has anyone had this problem? Thank you for your interest.

While recording a video, if an interruption occurs such as an incoming call or an alarm sound, the camera frezees and the video is not saved. I would like to handle this situation interrupting the video and saving it or removing the audio while it keeps recording. But after the interruption starts and the event is recognized, the variables regarding the video already recorded are reinitialized, causing the app not to save anything. This is part of the CameraManager class: var captureSession: AVCaptureSession? public func fileOutput(_: AVCaptureFileOutput, didStartRecordingTo _: URL, from _: [AVCaptureConnection]) { NotificationCenter.default.addObserver(self, selector: #selector(sessionInterruptionBegin), name: .AVCaptureSessionWasInterrupted, object: captureSession) NotificationCenter.default.addObserver(self, selector: #selector(sessionInterruptionEnd),name: .AVCaptureSessionInterruptionEnded, object: captureSession) NotificationCenter.default.addObserver(self, selector: #selector(audioSessionInterrupted), name: AVAudioSession.interruptionNotification, object: AVAudioSession.sharedInstance) print("STO PASSANDO DA AVCaptureFileOutputRecordingDelegate") captureSession?.beginConfiguration() if flashMode != .off { _updateIlluminationMode(flashMode) } captureSession?.commitConfiguration() //at this point captureSession starts collecting data about the video } extension CameraManager { @objc func sessionInterruptionBegin(notification: Notification) { print("Capture Session Interruption begin Notification!") guard let reasonNumber = notification.userInfo?[AVCaptureSessionInterruptionReasonKey] as? NSNumber else { return } let reason = AVCaptureSession.InterruptionReason(rawValue: reasonNumber.intValue) switch reason { case .audioDeviceInUseByAnotherClient: removeAudioInput() default: break } } func addAudioInput() throws { if audioDeviceInput != nil { return } removeAudioInput() print("Adding audio input...") captureSession?.beginConfiguration() guard let audioDevice = AVCaptureDevice.default(for: .audio) else { throw NSError() } audioDeviceInput = try AVCaptureDeviceInput(device: audioDevice) guard captureSession!.canAddInput(audioDeviceInput!) else { throw NSError() } captureSession?.addInput(audioDeviceInput!) captureSession?.automaticallyConfiguresApplicationAudioSession = false captureSession?.commitConfiguration() } func removeAudioInput() { //when the code reaches this point audioDeviceInput is reinitialized so the audio session is not removed from the recording //captureSession is not filled with the data about the video recorded guard let audioInput = audioDeviceInput else { return } captureSession?.beginConfiguration() captureSession?.removeInput(audioInput) audioDeviceInput = nil captureSession?.commitConfiguration() } @objc func sessionInterruptionEnd(notification: Notification) { print("Capture Session Interruption end Notification!") guard let reasonNumber = notification.userInfo?[AVCaptureSessionInterruptionReasonKey] as? NSNumber else { return } let reason = AVCaptureSession.InterruptionReason(rawValue: reasonNumber.intValue) switch reason { case .audioDeviceInUseByAnotherClient: // add audio again because we removed it when we received the interruption. configureAudioSession() default: // don't do anything, iOS will automatically resume session break } } @objc func audioSessionInterrupted(notification: Notification) { print("Audio Session Interruption Notification!") guard let userInfo = notification.userInfo, let typeValue = userInfo[AVAudioSessionInterruptionTypeKey] as?

Ever since using Xcode 14 SDK to compile, the iOS keyboard takes a long, variable, time to appear when focusing a UITextField or UITextView. I can confirm that using the previous SDK, the notification keyboardWillShow fires instantly, while in the current 14 SDK it takes a considerable amount of time, and not just the first time the keyboard opens. It always dismisses instantly. Is there any way to make the keyboard appear more quickly? Sometimes UI needs to move in sync with the keyboard and we need to know the keyboard height ASAP so it doesn't feel delayed. Even without needing the notification sooner, my app feels more delayed in general since selecting a text view takes longer for the keyboard to appear. Is there any way to debug why, or speed this up? It seems in the Notes app the keyboard appears instantly.

I'm facing an issue about Push Notification with Notification Service Extension (NSE). Steps: Allow Push Permissions and a valid device_token has been returned. The Push Notification come successfully and has handled by NSE. The NSE take some seconds for complete. When a Push is coming and the NSE is processing (not call contentHandler yet). Quickly delete the app. Then, we reinstall the app. Now, we can see: A content of push was called to didReceiveRemoteNotification of AppDelegate of main app (Not NSE). A valid device token has been returned to didRegisterForRemoteNotificationsWithDeviceToken without calling registerForRemoteNotifications and any Permissions. We can use this device_token to push. I can see it on: iOS 16.3 (Beta), iOS 16.1.1 (Final)... I can check the Permissions of the Push Notification before use the device_token. But It doesn't make sense. Do we have some best solutions for this? Thanks.

expect: app update UserDefaults use group value. widget use NotificationCenter.default observe same group UserDefaults, then reloadTimeline actual: successfully set no reload happen, and I try set same key to another value inside the selector function to test whether it's been called. provided the selector not work. steps: click a app button to set a key of UserDefaults back home , widget no change - expect it update view based one new value rebuild widget , can see the ui use new value - prove set call successfully but notification of UserDefaults.didChangeNotification not send host app : UserDefaults(suiteName: "group.a") store?.setValue("a", forKey: "target") widget: class NotiWatch {    init(){         NotificationCenter.default.addObserver(self, selector: #selector(onchange), name: UserDefaults.didChangeNotification, object: nil)     }     @objc func onchange(notification: NSNotification) {         UserDefaults(suiteName: "group.a")?.set("cccc", forKey: "target") WidgetCenter.shared.reloadAllTimelines()     }     deinit{         NotificationCenter.default.removeObserver(self, name: UserDefaults.didChangeNotification, object: nil)     } } struct Provider: TimelineProvider {     let def:UserDefaults? ;     let watcher = NotiWatch()     init(){         let fmt = DateFormatter()         fmt.dateFormat = "yyyy-MM-dd HH:mm"         dd = fmt.date(from: "2070-12-20 23:59")!         def = UserDefaults(suiteName: "group.a") ;     }     var dd =  Date()     func placeholder(in context: Context) -> SimpleEntry {         SimpleEntry(date: Date(), unit: "Y",left: 0,tar: "")     }     func getSnapshot(  in context: Context, completion: @escaping (SimpleEntry) -> ()) {         let date = Date()         let left = dd.timeIntervalSince(date).minutes         let entry = SimpleEntry(date: date, unit: "M",left: left,tar: "")                   completion(entry)     }     func getTimeline( in context: Context, completion: @escaping (Timeline<Entry>) -> ()) {         var entries: [SimpleEntry] = []         // Generate a timeline consisting of five entries an hour apart, starting from the current date.         let tar = def?.string(forKey: "target") ??

I'm working on an business tool app that supports offline work in areas without network access. while the offline activity is logged and saved locally, I need users to log in online in order for the app to report the offline activity audit back to the backend as soon as possible (once the phone has network access again) so the data is available to their managers. I am trying to find a way to trigger a local notification to remind the user of this required action once the phone regains connectivity, even if the app is in the background or not in memory at all. looking at the 4 available types of UNNotificationTrigger - the recommended way to trigger pending local notification, none of them supports the required functionality. using background capabilities also doesn't seem to be the correct way to approach this. In looking for similar questions online, couldn't find one addressing a similar scenario. Any ideas on how this can be achieved?

Our application uses UserNotificationCenter to deliver notifications of missed calls to the lock screen. Some times we need to remove this notification. I've tried to use removeDeliveredNotificationsWithIdentifiers APIs to remove the exact notification, but approximately in 10% tests it doesn't work. The issue happens when the app is in background, the user receives a APNS call, but answers on it from other endpoint, so for the app this call is missed. But after call history update it should be marked as answered and a missed call notification should be removed. From console logs I've found that for a good case system logs an attempt to remove a notification: default 14:31:03.376780+0100 [com.myapp] Removing 1 delivered notifications with identifiers ( "7C1E-73F2" ) SpringBoard default 14:31:03.377662+0100 [com.myapp] Removing delivered notifications SpringBoard default 14:31:03.388840+0100 Saving file at /var/mobile/Library/UserNotifications/6E65DC61-BF32-468B-B1A3-CD5B10F811BA/DeliveredNotifications.plist with 0 items SpringBoard default 14:31:03.399219+0100 kExcludedFromBackupXattrName set on path: SpringBoard error 14:31:03.400708+0100 No data found at /var/mobile/Library/UserNotifications/6E65DC61-BF32-468B-B1A3-CD5B10F811BA/PendingNotifications.plist SpringBoard default 14:31:03.400930+0100 [com.myapp] Load 0 pending notification dictionaries SpringBoard default 14:31:03.401433+0100 [com.myapp] Withdrawing notification 7C1E-73F2 SpringBoard default 14:31:03.402173+0100 BBDataProvider: Withdraw bulletin in section com.myapp publisher bulletin ID MissedCallCategory66071282 SpringBoard default 14:31:03.402455+0100 BBServer: Withdraw bulletin: 366E6C8B-DA60-4054-8CD2-238C3B95F7B3 SpringBoard default 14:31:03.402590+0100 Server has been asked to remove bulletin: 366E6C8B-DA60-4054-8CD2-238C3B95F7B3 SpringBoard default 14:31:03.403140+0100 Sending remove bulletin with transactionID 2, bulletin 366E6C8B-DA60-4054-8CD2-238C3B95F7B3 SpringBoard default 14:31:03.410509+0100 Sending remove bulletin with transactionID 2, bulletin 366E6C8B-DA60-4054-8CD2-238C3B95F7B3 SpringBoard default 14:31:03.411015+0100 Can't send remove bulletin.

I've tried to use removeAllDeliveredNotifications it works, but it could remove other notification, which should be present, this not a case here. There're some suggestions to use delays in code to adjust system's behavior, but it didn't help, still not fully stable. https://stackoverflow.com/questions/53697279/why-are-notifications-not-removed-with-removedeliverednotifications Is there anything what could be done from the app side to void this issue?

So both me and the girlfriend are running the same iPad’s and iOS. We can’t make a photo widget, here is the steps I tried to fix it: Click on Settings -> (tap on your User ID). Click on iCloud -> Photos -> turn off Sync this iPad. Click on General -> Shut Down (turn off iPad). Turn on iPad, Click on Settings -> (tap on User ID). Click on iCloud -> Photos turn Sync this iPad back on (you will see: in Cloud [ Updating ] Status [ syncing items ]. Click on main screen until you see + in the upper right corner. Click on photos (you should see photos)

For several times I asked Apple engineers to fix the problem with push notifications from iCloud email in native mail app. They partly did it - but when I’m offline for hour or more, I don’t receive them. At the same time if there’s a new mail which was sent less than hour during this period it will push more old notification. I’ve checked it in the following versions: iOS 16.1.2; iPadOS 16.1.2. Seems that the problem is close to being solved, but not for 100% yet. Who’s the same problem?

I have an app which uses MDM settings pushed from Miradore. I can read out the settings using: NSDictionary *serverConfig = [[NSUserDefaults standardUserDefaults] dictionaryForKey:"com.apple.configuration.managed"]; I want to add an observer to only trigger a function when "com.apple.configuration.managed" is changed and no other NSUserDefaults value. Currently the observer is triggered for all NSUserDefaults changes. The code for this that I have is: [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(readDefaultsValues:) name:NSUserDefaultsDidChangeNotification object:nil]; Does anyone know how to only observe changes to "com.apple.configuration.managed"?

A website created for Android that incorporates a push notification function does not work even when accessed with Safari on OS Ventura 13.0.1. I don't know what the problem is and what is needed, so please let me know if you have any examples or samples.

My use case : i want the app to completely silence a given received alert push notification, based on information the app has locally (completely remove it, and never even display it. Not just change the sound or badge). So far i found no way of doing that : notification service extension doesn't let you remove the notification entirely, just change its content. Using "background / content" notification type then creating the notification locally doesn't work, since "background" notification type is unreliable by design. voip notifications are banned from being used as a general-purpose background notification mechanism since iOS13 Help would be greatly appreciated.

Hello team, We have implemented push notification in our app. We are not supporting the in app badge count but we are showing the app icon badge count.  We are trying to increase the badge count for the received notifications count parallely it should decrease while opening the app by clicking on the notification or it should decrease while clearing the notification.  Also we are trying to achieve the overall badge count to reset to zero while clearing the notification from the notification center… Please let us know the possible way to achieve this. Thanks In Advance!!
