Hello, I have been using the App-prefs:General&path=SOFTWARE_UPDATE_LINK URL in my application to navigate to system settings, and it worked as expected. However, after updating to iOS 18, it no longer works, and I haven't been able to find a replacement. Is there any alternative solution or a different URL that works? I also tried prefs:root=General&path=SOFTWARE_UPDATE_LINK, but it didn’t work either.

we have three problem when using the push notification on Live Activity. 1. What is the specific callback strategy for the activityUpdates property in ActivityKit? We found that in actual user scenarios, there is a probability that we may not receive callbacks. From the community experience, there are some resource optimization strategies that do not perform callbacks. From this perspective, the explanation is kind of vague. Is there any clear feedback to understand why callbacks are performed/not performed? 2.what is the specific description of the wake-up strategy, when background app receive Live Activity offline start Push? From community experience, we can see that the system may wake up for a duration of 0-30s due to resource optimization strategies, or not wake up/not deal with it. Is there an official description of the wake-up strategy? or we also have to follow this description: Wake up of apps using content-available pushes are heavily throttled. You can expect 1-2 wakeup per hour as a best case scenario in the hands of your users. so this cannot be assumed to be a reliable wake-up on demand mechanism for an app. 3 How can we determine user have selected (allow or always allow) of the Live Activity permission? When we use real-time activity offline push, there are two system prompts in iOS: the first prompt : allow and disallow real-time activity the second prompt : always allow and disallow Is there an interface that can directly determine which permission the user has chosen (allow/always allow)? (By the way, we can get disallow status). At present, we haven't seen any interface in the official documentation/interface that can determine (allow/always allow). The difference here will affect the generation of Update Token. Without Update Token, we can not update our activity instance.

I have two standalone app written for watchos (standalone). One to authenticate and one for connectivity to real-world devices. The connectivity app uses the authentication app before every action, Im testing this with two xcode projects I have created and tried different things ended up with this error. authapp://authenticate?callback=linkingapp://callback -[SPApplicationDelegate extensionConnection:openSystemURL:]:2418: URL with scheme "authapp" not supported how to get the url scheme working? Tested this in simulator and real device. info.plist and AppDelegate files are placed in both apps.

There are different kinds of screen-sharing applications, all using different APIs. The API used by AnyDesk, for example, or TeamViewer, which doesn't require light signals. I wonder if this is more appropriate for a corporate application, i.e. MDM, A screen-sharing application could be created and validated by Apple to display no light signals, and which could access the user's screen whenever the person wanted to after an initial acceptance? In other words, the user accepts to share his screen once, but won't be notified to accept the next time. Or is this impossible on iOS? I'd be honored to have some answers

Hello, I'm trying to display some Duration in a live activity using a custom format, with the goal of displaying a match time (only minutes) as, e.g. 33', 45' (+2), etc. For that purpose, I'm using a TimeDataSource<Duration>, so that it also updates automatically given a starting point. I've implemented my custom FormatStyle, trying to somehow mimic the existing UnitsFormatStyle (which perfectly works with live activities) but just changing the format. I've added conformance to DiscreteFormatStyle, and code-wise everything seems to be ok (if I've understood things correctly). It compiles and it even works as expected in a playground. However, when trying to use it within the live activity, I'm getting these cryptic errors in the Console.app, and the live activity just turns into a view with placeholders Failed to fetch view from archive at index 12: SwiftUI.AnyCodable<SwiftUI.(unknown context at $1d47f6af0).SafelyCodableRequirement>.(unknown context at $1d47fe410).Errors.noType(mangledName: "7SwiftUI18TimeDataFormattingO10ResolvableVy_AA0cD6SourceVAAE15DurationStorageOys0H0V_GAK28BlickLiveActivitiesExtensionE16MatchFormatStyleVG") [624AEC37-13D9-4927-9F41-C3092B61E214] Failed to return view entry from archive for view model with tag listItem with error: SwiftUI.AnyCodable<SwiftUI.(unknown context at $1d47f6af0).SafelyCodableRequirement>.(unknown context at $1d47fe410).Errors.noType(mangledName: "7SwiftUI18TimeDataFormattingO10ResolvableVy_AA0cD6SourceVAAE15DurationStorageOys0H0V_GAK28BlickLiveActivitiesExtensionE16MatchFormatStyleVG") Are there any limitations when it comes to live activities and these custom formatters? This whole error doesn't make sense, since I'm only aiming to update every minute, which should just be fine, the same thing I get with the UnitsFormatStyle. For reference, this is my playground, which just works as expected: import Foundation import SwiftUI import PlaygroundSupport extension Duration { struct MatchFormatStyle: DiscreteFormatStyle, Sendable { let periodLength: Int let overtime: Int func format(_ value: Duration) -> String { let (seconds, _): (Int64, Int64) = value.components let minutes: Int = Int(seconds) / 60 let current: Int = periodLength + minutes + overtime if current > periodLength { return "\(periodLength)' (+\(current - periodLength))" } else { return "\(current)'" } } func discreteInput(before input: Duration) -> Duration? { let (seconds, _): (Int64, Int64) = input.components let minutes: Int64 = seconds / 60 - 1 return Duration(secondsComponent: minutes * 60, attosecondsComponent: .zero) } func discreteInput(after input: Duration) -> Duration? { let (seconds, _): (Int64, Int64) = input.components let minutes: Int64 = seconds / 60 + 1 return Duration(secondsComponent: minutes * 60, attosecondsComponent: .zero) } } } extension FormatStyle where Self == Duration.MatchFormatStyle { static func matchTime(currentTime: Int, periodLength: Int) -> Duration.MatchFormatStyle { return Duration.MatchFormatStyle(periodLength: periodLength, overtime: max(currentTime - periodLength, .zero)) } } extension TimeDataSource<Date> { static func matchDuration(for currentTime: Int, periodLength: Int) -> TimeDataSource<Duration> { let minutesAhead: Double = Double(max(periodLength - currentTime + 1, .zero)) return TimeDataSource<Date>.durationOffset(to: Date.now.addingTimeInterval(minutesAhead * 60)) } } struct FooView: View { let currentTime: Int = 36 let periodLength: Int = 45 var body: some View { Text( TimeDataSource<Date>.matchDuration(for: currentTime, periodLength: periodLength), format: .matchTime(currentTime: currentTime, periodLength: periodLength) ) .frame(width: 400, height: 200) .font(.system(size: 50)) } } // Present the view controller in the Live View window PlaygroundPage.current.setLiveView(FooView()) Any hints or suggestions are welcome, many thanks in advance.

Hey, I would love to access the users Contact (ie. the Me Card) Apple recently released the Invites app and within this app you can find the users Contacts Photo. I tried to replicate this behaviour but I currently need to match based on a name or email or something else. I have no idea how to receive this data because when using the Invites app I only remember the app asking for Contacts permission and nothing else so far. let store = CNContactStore() let keysToFetch = [CNContactImageDataAvailableKey, CNContactImageDataKey, CNContactThumbnailImageDataKey] as [CNKeyDescriptor] let email = "test@test.de" let predicate = CNContact.predicateForContacts(matchingEmailAddress: email) do { let contacts = try store.unifiedContacts(matching: predicate, keysToFetch: keysToFetch) let imageDatas: [Data] = contacts.compactMap { $0.imageData } self.images = imageDatas.map { UIImage(data: $0) ?? UIImage() } } catch { print("Error fetching contacts: \(error)") } This is how I am retrieving the Image. MAYBE someone can help me out. Thank you so far ~ Flo

After the app is put in background for sometime and brought in to foreground and the app crashes each time with a different thread stack entries but all of them states same exception reason.

Is there a way to create a Date constant from year, month and day? The only constructors that show up are .now and those based on some timeInterval. I'm trying to initialize some test data with known dates.

When using CallKit in my flutter app audio(both mic and speaker) stop working. When not using call kit to answer calls the app work fine. I am using the flutter flutter_callkit_incoming to use callkit and flutter_webrtc for the telephony. Flutter_callkit_incoming has some boilerplate code code include sections to uncomment when using webrtc and I have seen multiple fixes to suggest to make sure the to configure sharedAudioSession before the callkit is sent. Neither of this approaches seemed to have worked.

Hello everyone, I’m running an Objective-C–based hybrid (native + web) shopping application and encountering a recurring issue on devices running iOS 18.1.1: When the app launches, it only shows a white screen with the native frame visible—no web content loads. Restarting or reinstalling the app doesn’t help. In one instance, toggling Airplane Mode on and off brought the app back to normal, but this workaround isn’t consistent. There are no crash logs, so we can’t determine if it’s caused by a network error, cache conflict, or an OS-level bug. So far, we have only seen this issue on iOS 18.1.1 devices. Because our app is a shopping platform, this significantly impacts users. Questions: Could this be related to a known bug or limitation in iOS 18.1.1? Are there recommended diagnostic steps or workarounds for a hybrid app that shows a white screen without generating crash logs? Which additional details (e.g., system logs, network traces, device configurations) might help isolate the cause? Any insights or suggestions would be greatly appreciated. Thank you in advance!

I'm trying to build an app with a DeviceActivityMonitor extension that executes some code after 15 minutes. I can confirm that the extension is set up correctly and that intervalDidStart is executed, but for some reason the intervalDidEnd method never gets called. What I'm doing in both is just registering a local notification. class DeviceActivityMonitorExtension: DeviceActivityMonitor { let store = ManagedSettingsStore() override func intervalDidStart(for activity: DeviceActivityName) { createPushNotification( title: "Session activated!", body: "" ) super.intervalDidStart(for: activity) } override func intervalDidEnd(for activity: DeviceActivityName) { createPushNotification( title: "Session ended", body: "" ) super.intervalDidEnd(for: activity) } private func createPushNotification(title: String, body: String) { let content = UNMutableNotificationContent() content.title = title content.body = body // Configure the recurring date. var dateComponents = Calendar.current.dateComponents([.era, .year, .month, .day, .hour, .minute, .second], from: Date().addingTimeInterval(1.0)) dateComponents.calendar = Calendar.current dateComponents.timeZone = TimeZone.current // Create the trigger as a repeating event. let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: false) let uuidString = UUID().uuidString let request = UNNotificationRequest(identifier: uuidString, content: content, trigger: trigger) // Schedule the request with the system. let notificationCenter = UNUserNotificationCenter.current() notificationCenter.add(request) } } And this is the method that is starting the monitoring session: @objc public static func startSession() -> String? { // Calculate start and end times let center = DeviceActivityCenter() let minutes = 15 let startDate = Date().addingTimeInterval(1) guard let endDate = Calendar.current.date(byAdding: .minute, value: minutes, to: startDate) else { return "Failed to create end date?" } // Create date components and explicitly set the calendar and timeZone let startComponents = Calendar.current.dateComponents([.era, .year, .month, .day, .hour, .minute, .second], from: startDate) let endComponents = Calendar.current.dateComponents([.era, .year, .month, .day, .hour, .minute, .second], from: endDate) // Create schedule let schedule = DeviceActivitySchedule( intervalStart: startComponents, intervalEnd: endComponents, repeats: false ) print("Now", Date()) print("Start", startDate, startComponents) print("End", endDate, endComponents) print(schedule.nextInterval) do { // Use a consistent activity name for our simple implementation let activity = DeviceActivityName("SimpleSession") try center.startMonitoring(activity, during: schedule) return nil } catch { return "Failed to start monitoring: \(error)" } } I can confirm my dates & date components make sense with the 4 print statements. Here is the output: Now 2025-02-12 04:21:32 +0000 Start 2025-02-12 04:21:33 +0000 era: 1 year: 2025 month: 2 day: 11 hour: 20 minute: 21 second: 33 isLeapMonth: false End 2025-02-12 04:36:33 +0000 era: 1 year: 2025 month: 2 day: 11 hour: 20 minute: 36 second: 33 isLeapMonth: false Optional(2025-02-12 04:21:33 +0000 to 2025-02-12 04:36:33 +0000) I get the Session activated! notification but never get the Session ended notification. Half an hour later, I've tried debugging the DeviceActivityCenter by printing out the activities property and can see that it is still there. When I try to print out the nextInterval property on the schedule object i get from calling center.schedule(for:), it returns nil. I'm running this on an iPhone 8 testing device with developer mode enabled. It has iOS 16.7.10. I'm totally lost as to how to get this to work.

Hi, I'm trying to setup PIR service for live caller id lookup (in python but based on swift example: https://github.com/apple/live-caller-id-lookup-example). The swift example provides utilities for database setup and encryption, but I can't find any specification about which key is used for database encryption and how the ios system knows about this key in order to be able to construct the PIR requests. So my question is how does the PIR service communicate the secret key to ios system or vice versa? (specific to the test environment, before onboarding)

Hi Apple Developer, I’m working on a message-filtering application and reviewing Apple's documentation on message filtering. The documentation clearly states that MMS messages can be filtered. (https://developer.apple.com/documentation/identitylookup/sms-and-mms-message-filtering) When we refer to MMS, it includes images, short videos, and other supported multimedia formats. However, the ILMessageFilterQueryRequest only provides the message body as a String, meaning we can access text and links but not images or other media files. Could you please confirm whether Apple allows third-party applications to access multimedia content sent from unknown numbers? Looking forward to your quick response. Thanks, Rijul Singhal

I am having an app in which we are using NEHotspotHelper to detect wifi changes. when I try to kill the app and network change detected, we are seeing logs in NEHotspotHelper* module and after that we are able see the logs indicating app launched in background. [Application] application(_:didFinishLaunchingWithOptions:), UIApplicationState: 2 But when I checked in the app stack, I couldn't find the app. Then I clicked icon to launch the app, it launched without splash screen as if it came from background. Need your support to understand this is expected behaviour.

I have an iOS app where the universal links are not working. Basically, I have double-checked the AASA file, and it's formatted correctly. It's in the right location .well-known subdirectory. I have checked other things as well. For my app, if the user has forgotten their password, they click on the Forgot Password option, which sends them an email, after which they click on a link; the link should open the iOS app, but is instead opening up the web browser. The format of the link matches the formatting in the AASA file. As well, I've checked associated domains as well. Using Postman, I can see that the AASA file is accessible. I have a feeling that the iOS app cannot fetch the AASA file, as I don't see any relevant swcd logs. My AASA file is located at: https://www.COMPANY_NAME.ca/.well-known/apple-app-site-association Please advise.

I just created watchOS app alone a few months ago but I wanted to make a complication extension for my Apple Watch face. Without the aid of existing iOS app

My app’s widget is not displaying correctly and only shows a blank white screen.

We have encountered an issue with the app where it fails to progress beyond the splash screen. Interestingly, the problem seems to resolve itself after either reinstalling the app or restarting the phone. This behavior is observed specifically in version 18.3.1. Could this issue be related to a network connection or initialization problem in this version? Any insights or recommendations would be appreciated. Thank you for your assistance!
