Error: com.apple.AuthenticationServices.Authorization Error Code 1000
I am getting this error when trying to run the app on an actual IOS device using testFlight. It works well on simulators. I am using expo to build my app. I have done the following: Added Sign in with Apple in Xcode for all the profiles ( i.e. debug and release) Set expo.ios.usesAppleSignIn to true in my app.json ( I think due to this I see Synced capabilities: Enabled: Sign In with Apple while building my app using eas build. ) Make sure that the provision profile has Sign in with App capability. What I am not able to understand is how option provided in provision profile works. Expo creates the profile with type "App Store". I think this is because I am building the expo app with production profile. Does this have to take anything with it? Does the profile with type "App Store" not work when I am testing the app using testFlight? I am so confused right now. Can someone help me figure out the actual issue? I have seen almost all the posts regarding this error. None of those helped! Thanks in advance!

How to find renamed app using old name in Spotlight?
We are planning on renaming our app. The new name is not like the current name. It will be renamed in the App Store as well as the App display name. Yet, we still want new and existing users to be able to find the app by using the old name in search/spotlight under iOS. A great example of this is entering Twitter to find the X app and it shows up in the App section in the Spotlight search. Are there any guidelines, settings, or tricks for doing this? Some have suggested adding a Spotlight search term but that will not have it show up in the App section I fear.

Is there a way for my macos app to run NSRunningApplication.terminate()?
When my macOS app (currently in TestFlight and set for Mac App Store distribution) tries to terminate another app, both terminate() and forceTerminate() consistently return false. However, I can retrieve a list of all running applications so some related APIs do work. I suspect this limitation is due to sandboxing. I have three questions: Is there any permission or entitlement I can add in Xcode to allow my app to terminate other applications? If no such permission exists, is there a way to guide users on how to launch my app (distributed through the Mac App Store) without sandboxing? For example, could they set it up to launch as a daemon or agent? If unsandboxing is impossible, would I need to create a separate target specifically without sandboxing? In other words, my MacOS app would communicate with my unsandboxed daemon that would do all the terminate()-ing?

Pull data on iOS App Homescreen Widget

I am interested in obtaining the following information regarding one of our Home Screen widgets: Pull the following data about the "my_app_widget" homepage widget in total and by month for the last 12 months (Sep '23 - Sep '24): Widget install events Unique widget installs Device type (iPad, iOS).

ActivityCategoryPolicy.all(except: allowList) blocks all apps, even the ones that should be exempted
Hello fellow Screen Time developers! I have bee experimenting with the ActivityCategoryPolicy.all(except: allowList) API of the ManagedSettings framework in order to provide a digital detox feature to my app, where ALL apps would be blocked, except some important ones (phone, messages, maps). The apps to be exempted can be configured by the user via the FamilyActivitySelection(). However, I am experiencing a strange bug, where all apps are restricted / blocked, even the ones that are set to be exempted and are part of the allowList Set. Instead of not restricting allowed apps at all, these apps are restricted with a generic shield (screenshot below) – a concrete shield is not requested for them from my ShieldConfigurationDataSource. I have also filed a radar under this number, attached is a minimalistic sample project and video that shows how to reproduce this: FB15500605 (no response so far) I have also seen other people report on this issue, but couldn't find any useful information there: https://forums.developer.apple.com/forums/thread/750988 https://forums.developer.apple.com/forums/thread/762287 Thanks a lot for your help, and have a nice day!

Tokens change without reason after updating to iOS 17.5.1
Some of our users encounter an issue after updating their iPhone/iPad to iOS 17.5.1. The tokens passed in the Shield Configuration extension don't match the tokens they selected in my app using the FamilyPicker before updating to iOS 17.5.1. It seems the tokens changed for no reason. My app can't match the token from the ShieldConfigurationDataSource to any tokens stored on my end, causing my shield screens to turn blank. The same applies to tokens in the Device Activity Report extension. The only workaround I've found is to tell affected users to unselect and reselect apps and websites to block in my app. This gets them new tokens from the FamilyActivityPicker, which solves the issue. However, for some users, the bug reoccurs a few days later. Tokens seem to change again, causing the same issue in the Shield Configuration extension. I am not able to reproduce the issue on my test devices so I have no sysdiagnose to attach. However, this issue is affecting other screen time apps: https://developer.apple.com/forums/thread/732845 https://forums.developer.apple.com/forums/thread/756440 FB14082790 FB14111223 A change in iOS 17.5.1 must have triggered this behaviour. Could an Apple engineer give us any updates on this?

Google admob not working for specific bundle identifier iOS
I'm integrating AdMob rewarded interstitial ads into my live iOS app using CocoaPods and package dependency management. The ads are working fine when I use the bundle identifier com.CreativeCub.ProgrammingHu, but when I use the correct identifier com.CreativeCub.ProgrammingHub, the ads stop working. Here’s what I’ve tried: Verified that the bundle identifier matches across Xcode and AdMob. Double-checked the App ID and Ad Unit ID in the AdMob dashboard for com.CreativeCub.ProgrammingHub. Reinstalled the AdMob SDK using CocoaPods. Attempted to integrate AdMob using Swift Package Manager. Created a test project to rule out potential issues with my existing project. Despite these steps, ads only work when I use the shortened bundle identifier (com.CreativeCub.ProgrammingHu), which is not the correct one. Contacted Google admob support for the same but did not worked Tried running in different MacBook system

iOS App terminates but does not generate Crash Report
The app exits immediately on startup, there is no crash message, and I can't get any valuable diagnostic information. It doesn't even get to the main function. It feels like exit is being called somewhere, and then I used atexit to register the relevant handler. Finally, I found the following stack printout It looks like it's a dynamic linking issue, so what's the best way to troubleshoot it. This problem only occurs in release versions.

PDFKit PDFPage.characterBounds(at:) returns incorrect coordinates iOS 18 beta 4
PDFKit PDFPage.characterBounds(at: Int) is returning incorrect coordinates with iOS 18 beta 4 and later / Xcode 16 beta 4. It worked fine in iOS 17 and earlier (after showing the same issue during the early iOS 17 beta cycle) It breaks critical functionality that my app relies on. I have filed feedback (FB14843671). So far no changes in the latest betas. iOS release date is approaching fast! Anybody having the same issue? Any workaround available?

Sonoma: Is It No Longer Possible to Fetch Wallpaper File Names?
Under Ventura, desktop wallpaper image names were stored in a sqlite database at ~/Library/Application Support/Dock/desktoppicture.db. This file is no longer being used under Sonoma. I have a process I built that fetches the desktop image file names and displays them, either as a service, or on the desktop. I do this because I have many photos I've taken, and I like to know which one I'm viewing so I can make edits if necessary. I set these images across five spaces and have them randomly change every hour. I tried using AppleScript but it would not pull the file names. A few people have pointed me to ~/Library/Application Support/com.apple.wallpaper/Store/Index.plist. However, on my system, this only reveals the source folder and not the image name itself. On one of my Macs, it shows 64 items, even though I have only five spaces! Is there a way to fetch the image file names under Sonoma? Will Sequoia make this easier or harder?

System search AssistantIntent not working
@available(iOS 18.0, *) @AssistantIntent(schema: .system.search) struct SearchIntent: AppIntent { static let title: LocalizedStringResource = "Search <app name redacted>" static let searchScopes: [StringSearchScope] = [.general] @Parameter(title: "Criteria") var criteria: StringSearchCriteria @MainActor func perform() async throws -> some IntentResult { MyDependencyManager.shared.performSearch(with: criteria.term) return .result() } } // In AppShortcutProvider AppShortcut( intent: SearchIntent(), phrases: [ "Find \(\.$criteria) in \(.applicationName)", "Search for \(\.$criteria) in \(.applicationName)", ], shortTitle: "Search <app name redacted>", systemImageName: "magnifyingglass" ) The search works when using the Shortcuts app, but not when using Siri. For example if I ask Siri "Search for in " it just does a Google search or prompts me to install the app from the App Store (I am running a debug build via Xcode). I can't get this to work from Spotlight either. I am using Xcode 16 and running the app on an iPhone 16 with OS 18.2 beta and Apple Intelligence turned on. What am I doing wrong here? I cannot find any other information about this intent or how to properly set it up and use it.

Issue with Siri Not Displaying Prompt in App Intent
Hello everyone, I'm currently working on an App Intent for my iOS app, and I’ve encountered a frustrating issue related to how Siri prompts for a category selection. Here’s an overview of what I’m dealing with: extension Category: AppEntity, @unchecked Sendable { var displayRepresentation: DisplayRepresentation { DisplayRepresentation(title: "\(name)") } static var typeDisplayRepresentation = TypeDisplayRepresentation(name: "Category") typealias DefaultQueryType = ShortcutsCategoryQuery static var defaultQuery: ShortcutsCategoryQuery = ShortcutsCategoryQuery() } struct ShortcutsCategoryQuery: EntityQuery { func entities(for identifiers: [String]) async throws -> [Category] { let context = await ModelContext(sharedModelContainer) let categories = try CategoryDataProvider(context: context).getItems() return categories.filter { identifiers.contains($0.id) } } func entities(matching string: String) async throws -> [Category] { return try await suggestedEntities() } func suggestedEntities() async throws -> [Category] { let context = await ModelContext(sharedModelContainer) do { let categories = try CategoryDataProvider(context: context).getItems() if categories.isEmpty { print("No categories found.") } return categories.map { category in Category( id: category.id, name: category.name, stringSymbol: category.stringSymbol, symbol: category.symbol, stringColor: category.stringColor, color: category.color ) } } catch { print(error) return [] } } } The issue arises when I use Siri to invoke the intent. Siri correctly asks me to select a category but does not display any options unless I said something that Siri recognized, like "Casa(House) or *****(Test)" in portuguese. Only then does it show the list of available categories. I would like the categories to appear immediately when Siri asks for a selection. I've already tried refining the ShortcutsCategoryQuery and debugging various parts of my code, but nothing seems to fix this behavior.

Does Live Activity always receive updates for pushToStartTokenUpdates and activityUpdates?
Our context involves smart kitchen appliances, where cooking may be initiated by an app or directly by the device. When the app is not running, we can only start a Live Activity through a remote push notification. However, an increasing number of users report issues where they cannot update or terminate the Live Activity. While we can reproduce this issue in some cases, it is inconsistent and lacks a clear pattern. I have a sample project and would like to confirm the following questions: When the app is not running, does each pushToStartToken update wake the app and reliably trigger the callback below? for await pushToken in Activity<DeviceAttributes>.pushToStartTokenUpdates { } When the app is not running, does each pushTokenUpdates update wake the app and reliably trigger the callback below? Task { for await activity in Activity<DeviceAttributes>.activityUpdates { Task { for try await tokenData in activity.pushTokenUpdates { } } } } Must pushToStartTokenUpdates and pushTokenUpdates be placed directly in application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?), or can they be in another wrapper, such as an RxSwift wrapper? If pushTokenUpdates is updated, but the received pushToken fails to synchronize to the server due to network issues, how should this be handled? Alternatively, if you have any better suggestions, I would be very grateful to hear them. Here is a simple example.

Widget Configuration's Selected Parameter Always Reverts to Default
I created an intent for a configurable widget that lets users choose an option for a parameter called "domain." I've successfully loaded the selectable items for this parameter using the following code: import Intents class IntentHandler: INExtension, ConfigChartIntentHandling { func provideDomainOptionsCollection(for intent: ConfigChartIntent) async throws -> INObjectCollection<Domain> { let prefs = UserDefaults(suiteName: "group.name") let domains = prefs?.stringArray(forKey: "domains") if let domains { let optionsCollection = domains.map { Domain(identifier: $0, display: $0) } return INObjectCollection(items: optionsCollection) } else { // If no options, provide an empty list or a default option return INObjectCollection(items: []) } } } The issue occurs when I select a value for the "domain" parameter. Each time I select a value and then reopen the configuration modal, the field reverts back to "Choose." Here's a screenshot illustrating the behavior: Additionally, the widget doesn’t refresh after I change the "domain" value. However, another parameter using an enum ("Stats Type") works as expected. Is there something I might be missing? My Environment: MacOS Sonoma XCode 15.4
