Screen Time API: How to map bundleIdentifier to ApplicationToken for DeviceActivityMonitor when FamilyActivitySelection.Application.bundleIdentifier is nil?
I'm using FamilyActivityPicker to get consent for app/category management, which returns a FamilyActivitySelection object. I serialize this FamilyActivitySelection object (just applicationTokens and categoryTokens) and pass it to my DeviceActivityMonitor extension via App Group UserDefaults. I am using the JSON encoder/decoder over PropertyList (though both seem to exhibit the same behavior). After inspecting the FamilyActivitySelection object immediately after it's returned by FamilyActivityPicker in the main app, the application.bundleIdentifier property is consistently nil for every Application object within selection.applications. Similarly, category.localizedDisplayName is nil for ActivityCategory objects. This happens whether "Select All Apps" is used or if apps/categories are selected individually. I understand that this is the intended behavior due to Apple's user privacy policies. I read on another post that my app can be provided with bundle identifiers and app names within Shield Configuration extensions and Device Activity Report extensions - I'm not sure which ones or how exactly to do this. I am aware that I can use Label(applicationToken) SwiftUI view to display the app name/icon, but this doesn't give programmatic access to the bundleIdentifier string. My app will not log or export these bundleIdentifiers outside of its sandbox. My goal is to create mappings to the FamilyActivitySelection with the publicly accessible bundleIdentifiers. Any guidance, examples, or clarification on the intended workflow for this scenario would be greatly appreciated!

Does Apple Screen Time API Allow Access to App Usage Data for Custom Rewards?
Hi everyone, I'm working on an app for parents and kids where parents can define screen time goals or restrict usage of certain app categories (like social media or games). If the kid follows those rules—for example, by using their device less or avoiding restricted categories—they would earn points or rewards in the app. I’ve been exploring if the Apple Screen Time API allows developers to access this kind of data (like total screen time, app usage by category, etc.) so that I can track the kid’s behavior and reward them accordingly. Is it possible to programmatically access this data and implement such a reward system within my app? If so, what’s the best way to get started or which APIs should I look into? Thanks in advance for your help!

Weatherkit API Historical 404 Errors Starting 3/5/25
We've been using the WeatherKit API for a few years now. Everything has been pretty stable. We'll periodically get 404 errors, but they usually disappear within a couple days. Starting March 5th we've again been getting 404 errors that slowly ramped up to March 20th and continued. We have had no code changes on our end, so something seems to have changed / broken on the server side of things. Here are some example API calls that are giving us a 404 error now https://weatherkit.apple.com/api/v1/weather/en/35.9981205/-78.8920444?dataSets=forecastDaily&dailyStart=2025-03-21T05:00:00Z&timezone=America/New_York&countryCode=US https://weatherkit.apple.com/api/v1/weather/en/41.4789363/-81.7404134?dataSets=forecastDaily&dailyStart=2025-03-21T04:56:00Z&timezone=America/New_York&countryCode=US Does anyone have any insights or information on this? Also if Apple is listening, an error more meaningful than 404 would be much much appreciated.

Testing TelephonyMessagingKit Outside of The EU
Is it possible to develop for TelephonyMessagingKit on iOS 26 outside of the EU? If so, how is this accomplished? I have added the 'Default Carrier Messaging App' entitlement to my project, but I do not see an option to set my app as a default option in settings on my device. I am not located inside of the EU, but would like to test this functionality.

iOS AirPrint sends print-quality=high when file-type is photo even if user selects “normal”
Hi everyone, I observed a behavior with AirPrint from an iPhone and wanted to confirm if this is expected behavior from iOS. Scenario tested: File type: Photo Print-quality selected by the user: Normal Observation (from packet capture): When checking the PCAP for the request sent from the iPhone, the print-quality attribute is always sent as high, even though the user selected Normal in the UI. Question: Is this an expected behavior in iOS/AirPrint where photos are always sent with print-quality=high regardless of the user-selected print quality? Or could this be a bug?

Supported URL Schemes
Some Apple URL schemes are documented for third-party use. It’s fine to use those URL schemes for their intended purpose. Other Apple URL schemes are not officially documented. Their use is unsupported. If you rely on such implementation details, things might work, or they might not, and that state might change over time. IMPORTANT If you ship via the App Store, pay attention to clause 2.5.1 of the App Review Guidelines. The Apple URL scheme documentation is not always easy to find. I’m aware of the following: Apple URL Scheme Reference QA1924 Opening Keyboard Settings from a Keyboard Extension [This Q&A was retired years ago.] Preparing your app to be the default messaging app The doc comments for es_new_client in <EndpointSecurity/ESClient.h> Developer > Bug Reporting describes the applefeedback scheme Additionally, as questions about this most commonly crop up in the context of opening Settings (System Settings on macOS), I wanted to highlight the following: UIApplication.openSettingsURLString property (in Objective-C this is UIApplicationOpenSettingsURLString) UIApplication.openNotificationSettingsURLString property (in Objective-C this is UIApplicationOpenNotificationSettingsURLString) UIApplication.openDefaultApplicationsSettingsURLString property (in Objective-C this is UIApplicationOpenDefaultApplicationsSettingsURLString) AccessibilitySettings.openSettings(for:) method FIFinderSyncController.showExtensionManagementInterface() class method SMAppService.openSystemSettingsLoginItems() class method VSOpenTVProviderSettingsURLString global CXCallDirectoryManager.openSettings(completionHandler:) method SFSafariSettings.openExportBrowsingDataSettings() method SFSafariSettings.openExtensionsSettings(forIdentifiers:) method If your app needs to perform some action that’s not covered by the above, file an enhancement request for a supported way to do that.

UI Testing and 'Allow Paste'
I am developing an app that allows the user to ask it to process the clipboard contents and do something with it. In developing a XC UI Test, I find the app stops while it waits for the user to give permission. That breaks the automation. I tried: let springboard = XCUIApplication(bundleIdentifier: "com.apple.springboard") let allowButton = springboard.buttons["Allow Paste"] But that does not work. Is there a way to tell the framework to automatically give the test permission to access the Paste clipboard (or to allow me to write tests to grant this)?

LiveCommunicationKit
What I want to achieve now is that when the app is not running, upon receiving a notification, it displays an interface similar to CallKit with accept and decline buttons. Here is part of my code: @available(iOS 17.4, *) class LiveCommunicationManager: NSObject, ConversationManagerDelegate { static let shared = LiveCommunicationManager() var isInvalidate:Bool = false var configuration: ConversationManager! override init() { let config = ConversationManager.Configuration( ringtoneName: "notes_of_the_optimistic", iconTemplateImageData: UIImage(named: "AppIcon")?.pngData(), // 图标的 PNG 数据 maximumConversationGroups: 1, // 最大对话组数 maximumConversationsPerConversationGroup: 1, // 每个对话组内最大对话数 includesConversationInRecents: false, // 是否在通话记录中显示 supportsVideo: false, // 是否支持视频 supportedHandleTypes: [.generic,.phoneNumber,.emailAddress] // 支持的通话类型 ) configuration = ConversationManager.init(configuration: config) } func reportIncomingCall(uuid: UUID, callerName: String) { configuration.delegate = self let local = Handle(type: .generic, value: callerName, displayName: callerName) let update = Conversation.Update(localMember: local,members: [local],activeRemoteMembers: [local]) Task{ do { try await configuration.reportNewIncomingConversation(uuid: uuid, update: update) print("成功报告新来电") } catch { print("报告新来电失败: \(error.localizedDescription)") } } } func conversationManager(_ manager: ConversationManager, conversationChanged conversation: Conversation) { print("会话状态改变了") } func conversationManagerDidBegin(_ manager: ConversationManager) { print("会话已经开始了") manager.delegate = self } func conversationManagerDidReset(_ manager: ConversationManager) { print("会话将要清除了") } func conversationManager(_ manager: ConversationManager, perform action: ConversationAction) { print("会话接听了") configuration.invalidate() } func conversationManager(_ manager: ConversationManager, timedOutPerforming action: ConversationAction) { print("会话超时了") } func conversationManager(_ manager: ConversationManager, didActivate audioSession: AVAudioSession) { print("会话激活了") } func conversationManager(_ manager: ConversationManager, didDeactivate audioSession: AVAudioSession) { print("会话死亡了") } } 在Appdelegate里设置了这些: func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -&gt; Void) { // 在这里处理离线推送通知 completionHandler(.noData) // 返回后台任务完成 if let aps = userInfo["aps"] as? [String: Any], let alert = aps["alert"] as? [String : Any]{ // 静默推送的处理逻辑 if #available(iOS 17.4, *) { let manager = LiveCommunicationManager.shared if manager.isInvalidate { return } if let msgType = userInfo["msgType"] as? Int{ if msgType == 5{ manager.configuration.invalidate() }else{ let callerName = alert["title"] as? String ?? "Fanvil" manager.reportIncomingCall(uuid: UUID(), callerName: callerName) } } } } } Xcode has been configured with the necessary capabilities, such as Background Fetch, Voice over IP, Background Processing, and Push Notification. The issue now is that sometimes the code works as expected, allowing the app to wake up when not running and displaying the system interface with accept and decline buttons. However, after a few successful attempts, the app stops waking up, and no notification appears. But when I manually open the app, the didReceiveRemoteNotification method gets triggered. I’d like to know why this stops working after a few times.

CarPlay Simulator: How to Change Dock Position for Right-Hand Drive (RHD)
Hello everyone, I'm developing a CarPlay app and am trying to test it with the dock on the right side of the screen, as is standard for right-hand drive vehicles like those in Japan. Currently, the CarPlay Simulator always displays the dock on the left, and I can't find an option to change its position. This is important for ensuring a proper user experience for my target market. Has anyone figured out how to configure the simulator for RHD layouts? Any guidance on how to move the dock to the right would be greatly appreciated. Thanks in advance for your help!

USB Control Transfers on Devices with CDC Serial Port
I have a USB-device with three interfaces: Vendor-Specific Bulk CDC Serial Control CDC Serial Data To configure the vendor specific bulk endpoints I need to send vendor specific control requests to endpoint 0. I'm using libusb for this task. As long as the interfaces for the CDC serial port are present I get an access error when trying to send vendor control requests. If I disable these CDC interfaces I can send vendor control request without any problems: Is this by design or ist there any possibility to send vendor control requests to the USB device while a CDC driver is active?

Kext loads well after launchd and early os_log entries rarely appear in unified log
Is there a way to ensure a kernel extension in the Auxiliary Kernel Collection loads (and runs its start routines) before launchd? I'm emitting logs via os_log_t created with an os_log_create (custom subsystem/category) in both my KMOD's start function and the IOService::start() function. Those messages-- which both say "I've been run"-- inconsistently show up in log show --predicate 'subsystem == "com.bluefalconhd.pandora"' --last boot, which makes me think they are running very early. However, I also record timestamps (using mach_absolute_time, etc.) and expose them to user space through an IOExternalMethod. The results (for the most recent boot): hayes@fortis Pandora/tests main % build/pdtest Pandora Metadata: kmod_start_time: Time: 2025-07-22 14:11:32.233 Mach time: 245612546 Nanos since boot: 10233856083 (10.23 seconds) io_service_start_time: Time: 2025-07-22 14:11:32.233 Mach time: 245613641 Nanos since boot: 10233901708 (10.23 seconds) user_client_init_time: Time: 2025-07-22 14:21:42.561 Mach time: 14893478355 Nanos since boot: 620561598125 (620.56 seconds) hayes@fortis Pandora/tests main % ps -p 1 -o lstart= Tue Jul 22 14:11:27 2025 Everything in the kernel extension appears to be loading after launchd (PID 1) starts. Also, the kext isn't doing anything crazy which could cause that kind of delay. For reference, here's the Info.plist: <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>CFBundleExecutable</key> <string>Pandora</string> <key>CFBundleIdentifier</key> <string>com.bluefalconhd.Pandora</string> <key>CFBundleName</key> <string>Pandora</string> <key>CFBundlePackageType</key> <string>KEXT</string> <key>CFBundleVersion</key> <string>1.0.7</string> <key>IOKitPersonalities</key> <dict> <key>Pandora</key> <dict> <key>CFBundleIdentifier</key> <string>com.bluefalconhd.Pandora</string> <key>IOClass</key> <string>Pandora</string> <key>IOMatchCategory</key> <string>Pandora</string> <key>IOProviderClass</key> <string>IOResources</string> <key>IOResourceMatch</key> <string>IOKit</string> <key>IOUserClientClass</key> <string>PandoraUserClient</string> </dict> </dict> <key>OSBundleLibraries</key> <dict> <key>com.apple.kpi.dsep</key> <string>24.2.0</string> <key>com.apple.kpi.iokit</key> <string>24.2.0</string> <key>com.apple.kpi.libkern</key> <string>24.2.0</string> <key>com.apple.kpi.mach</key> <string>24.2.0</string> </dict> </dict> </plist> My questions are: A. Why don't the early logs (from KMOD's start function and IOService::start) consistently appear in the unified log, while logs later in IOExternalMethods do? B. How can I force this kext to load earlier-- ideally before launchd? Thanks in advance for any guidance!

Family Controls Approved for Main App but Not Extension – Blocking
Hi everyone, I’m developing a screen-time and focus app that uses Apple’s Family Controls framework to block distracting apps and reward users through a gamified experience. Apple approved Family Controls (Distribution) for the main app identifier, but they did not approve the required extension target (which implements DeviceActivityMonitor, required for the framework to function). Because of this, I can’t archive or upload the app to TestFlight — and I’ve been stuck in limbo for over 2 months. This is severely delaying my launch. The app works perfectly, but I can’t release it because the extension wasn’t included in the entitlement approval. Has anyone else run into this with Family Controls? Is there any known way to escalate or fast-track approval for additional app IDs or targets? Would really appreciate any help, advice, or hacks. 🙏 Thanks, Enzer

How does ageGates actually affect the returned age range?
I’m trying to fully understand the purpose of the ageGates parameter in the AgeRangeService.requestAgeRange API. The official documentation includes the following statement: “The system may return geo-specific age ranges that override your provided age gates based on the person’s location and applicable regulations. When geo-specific ranges are required, the returned age range reflects regulatory requirements rather than the bounds of your age gates.” Based on this, it seems that even if my app provides specific age thresholds through the ageGates parameter, the system may override those boundaries depending on regional laws or regulations, and return a completely different lowerBound / upperBound than what my age gates would suggest. My current understanding is: ageGates indicates the thresholds my app uses to define its internal feature tiers, but the actual age range returned by the OS is determined by legal or regional requirements (e.g., COPPA, GDPR-K, AADC, SB2420), meaning the returned age range may not align with the age ranges implied by my ageGates values. I’d like to confirm whether this interpretation is correct. Additionally, if different regions may produce different lowerBound / upperBound values due to regulatory requirements, then it seems that: developers shouldn’t rely on fixed age buckets, and instead must implement feature gating logic dynamically based on whatever age range the OS returns. So my questions are: Is my understanding correct that ageGates is simply a hint that describes my app’s tier thresholds, and the OS may override those boundaries to comply with local regulations? If lowerBound / upperBound can vary across regions, what is the recommended way for developers to design their feature-gating logic? Should we avoid hardcoded age buckets and instead build flexible logic that adapts to whatever range the OS returns? I’d appreciate clarification so I can design our age-based policies appropriately and in a regulation-compliant way.

How to identify which minor user's authorization has been revoked by the parent/guardian?
I followed the method outlined in Apple's documentation to test "Revocation of Consent." Our server received the notification sent by Apple, but the parsed data only contains the following content (some data has been modified for privacy, but the fields remain unchanged): { "receiptType": "Sandbox", "bundleId": "com.xxx.xxxxx", "receiptCreationDate": 1764932591296, "requestDate": 1764932591296, "originalPurchaseDate": 1375340400000, "originalApplicationVersion": "1.0", "appTransactionId": "705020051250081000", "originalPlatform": "iOS" } How can we identify that "a parent/guardian has revoked authorization for a specific user"? We are unable to determine which minor user should be restricted from using certain features of our app. I hope to receive a prompt response from Apple's technical experts! Thanks A Lot !

How to debug a CoreSpotlight extension?
My CoreSpotlight extension seems to exceed the 6 MB memory limit. What’s the best way to debug this? I've tried to attach the debugger on the Simulator but the extension seems to be never launched when I trigger the reindex from Developer settings. Is this supposed to work? On device, I am able to attach the debugger. However, I can neither transfer the debug session to Instruments, nor display the memory graph. So I've no idea how the memory is used. Any recommendations how to move forward? Is there a way to temporarily disable the memory limit since even with LLDB attached, the extension is killed.

Opening two (or more files) with one dialog box (save panel)
I am slowly converting an Objective C with C program to Swift with C. All of my menus and dialog boxes are now in Swift, but files are still opened and closed in Objective C and C. The following code is Objective C and tries to open two files in the same directory with two related names after getting the base of the name from a Save Panel. The code you see was modified by ChatGPT 5.0, and similar code was modified by Claude. Both LLMs wrote code that failed because neither knows how to navigate Apple’s sandbox. Does anybody understand Apple’s sandbox? I eventually want to open more related files and do not want the user to have to click through multiple file dialog boxes. What is the best solution? Are the LLMs just not up to the task and there is a simple solution to the Objective C code? Is this easier in Swift? Other ideas? Thanks in advance for any help. (BOOL)setupOutputFilesWithBaseName:(NSString*)baseName { NSString *outFileNameStr = baseName; if (outFileNameStr == nil || [outFileNameStr length] == 0) { outFileNameStr = @"output"; } // Show ONE save panel for the base filename NSSavePanel *savePanel = [NSSavePanel savePanel]; [savePanel setMessage:@"Choose base name and location for output files\n(Two files will be created: one ending with 'Pkout', one with 'Freqout')"]; [savePanel setNameFieldStringValue:outFileNameStr]; if (directoryURL != nil) { [savePanel setDirectoryURL:directoryURL]; } if ([savePanel runModal] != NSModalResponseOK) { NSLog(@"User cancelled file selection"); return NO; } // Get the selected file URL - this gives us security access to the directory NSURL *baseFileURL = [savePanel URL]; // Get the directory - THIS is what we need for security scope NSURL *dirURL = [baseFileURL URLByDeletingLastPathComponent]; // Start accessing the DIRECTORY, not just the file BOOL didStartAccessing = [dirURL startAccessingSecurityScopedResource]; if (!didStartAccessing) { NSLog(@"Warning: Could not start security-scoped access to directory"); } NSString *baseFileName = [[baseFileURL lastPathComponent] stringByDeletingPathExtension]; NSString *extension = [baseFileURL pathExtension]; // Create the two file names with suffixes NSString *pkoutName = [baseFileName stringByAppendingString:@"Pkout"]; NSString *freqoutName = [baseFileName stringByAppendingString:@"Freqout"]; NSURL *pkoutURL = [dirURL URLByAppendingPathComponent:pkoutName]; NSURL *freqoutURL = [dirURL URLByAppendingPathComponent:freqoutName]; NSLog(@"Attempting to open: %@", [pkoutURL path]); NSLog(@"Attempting to open: %@", [freqoutURL path]); // Open the first file (Pkout) globalFpout = fopen([[pkoutURL path] UTF8String], "w+"); if (globalFpout == NULL) { int errnum = errno; NSLog(@"Error: Could not open Pkout file at %@", [pkoutURL path]); NSLog(@"Error code: %d - %s", errnum, strerror(errnum)); if (didStartAccessing) { [dirURL stopAccessingSecurityScopedResource]; } return NO; } NSLog(@":white_check_mark: Pkout file opened: %@", [pkoutURL path]); // Open the second file (Freqout) globalFpfrqout = fopen([[freqoutURL path] UTF8String], "w+"); if (globalFpfrqout == NULL) { int errnum = errno; NSLog(@"Error: Could not open Freqout file at %@", [freqoutURL path]); NSLog(@"Error code: %d - %s", errnum, strerror(errnum)); fclose(globalFpout); globalFpout = NULL; if (didStartAccessing) { [dirURL stopAccessingSecurityScopedResource]; } return NO; } NSLog(@":white_check_mark: Freqout file opened: %@", [freqoutURL path]); // Store the directory URL so we can stop accessing later secureDirectoryURL = dirURL; return YES; }

BLE Notification & Write Latency/Batching on iOS (vs Android) – CoreBluetooth Real-Time Question
I am using a Raspberry Pi 5 (BLE 5.0) to read sensor data and send it via D-Bus and BlueZ to a Flutter application (flutter_blue_plus) for both iOS and Android. The goal is to display these real-time sensor updates directly on the device. On Android, the data transmission is immediate and the real-time visualization is extremely smooth and fast. However, on iOS, both BLE write and notification commands appear with noticeable latency—not only in real-time displays, but also when comparing ordinary notification feedback between the Raspberry Pi terminal and the iOS app. It seems that iOS buffers several BLE packets internally and then dispatches them in batches, which always introduces an additional delay. Additional setup details: I sample and transmit data every 25ms, sending binary packets of 20 bytes (length shouldn’t be a limiting factor). On the iOS side I am using an iPhone 15 Pro with iOS 18.6.2 (BLE 5.3). The Raspberry Pi (using btmon for logging) confirms after connection setup that the connection interval is fixed at 30ms (and cannot be changed). I have tried sending BLE packets every 30ms so that exactly one packet arrives per interval, but this made no difference—the latency and batch delivery remain. Interestingly, faster transmission rates (e.g. sending every 10ms) make the real-time display look smoother on iOS, but the guaranteed overall system latency does not improve. Also these methods used: write-without-response, using app in release modus (no debugging) Is there anyone familiar with this problem or a potential solution? Or is iOS simply not optimized for true real-time BLE data streaming and visualization? Any pointers, technical insights or workarounds would be greatly appreciated.

Screen Time API: How to map bundleIdentifier to ApplicationToken for DeviceActivityMonitor when FamilyActivitySelection.Application.bundleIdentifier is nil?
I'm using FamilyActivityPicker to get consent for app/category management, which returns a FamilyActivitySelection object. I serialize this FamilyActivitySelection object (just applicationTokens and categoryTokens) and pass it to my DeviceActivityMonitor extension via App Group UserDefaults. I am using the JSON encoder/decoder over PropertyList (though both seem to exhibit the same behavior). After inspecting the FamilyActivitySelection object immediately after it's returned by FamilyActivityPicker in the main app, the application.bundleIdentifier property is consistently nil for every Application object within selection.applications. Similarly, category.localizedDisplayName is nil for ActivityCategory objects. This happens whether "Select All Apps" is used or if apps/categories are selected individually. I understand that this is the intended behavior due to Apple's user privacy policies. I read on another post that my app can be provided with bundle identifiers and app names within Shield Configuration extensions and Device Activity Report extensions - I'm not sure which ones or how exactly to do this. I am aware that I can use Label(applicationToken) SwiftUI view to display the app name/icon, but this doesn't give programmatic access to the bundleIdentifier string. My app will not log or export these bundleIdentifiers outside of its sandbox. My goal is to create mappings to the FamilyActivitySelection with the publicly accessible bundleIdentifiers. Any guidance, examples, or clarification on the intended workflow for this scenario would be greatly appreciated!

Weatherkit API Historical 404 Errors Starting 3/5/25
We've been using the WeatherKit API for a few years now. Everything has been pretty stable. We'll periodically get 404 errors, but they usually disappear within a couple days. Starting March 5th we've again been getting 404 errors that slowly ramped up to March 20th and continued. We have had no code changes on our end, so something seems to have changed / broken on the server side of things. Here are some example API calls that are giving us a 404 error now https://weatherkit.apple.com/api/v1/weather/en/35.9981205/-78.8920444?dataSets=forecastDaily&dailyStart=2025-03-21T05:00:00Z&timezone=America/New_York&countryCode=US https://weatherkit.apple.com/api/v1/weather/en/41.4789363/-81.7404134?dataSets=forecastDaily&dailyStart=2025-03-21T04:56:00Z&timezone=America/New_York&countryCode=US Does anyone have any insights or information on this? Also if Apple is listening, an error more meaningful than 404 would be much much appreciated.

Testing TelephonyMessagingKit Outside of The EU
Is it possible to develop for TelephonyMessagingKit on iOS 26 outside of the EU? If so, how is this accomplished? I have added the 'Default Carrier Messaging App' entitlement to my project, but I do not see an option to set my app as a default option in settings on my device. I am not located inside of the EU, but would like to test this functionality.

iOS AirPrint sends print-quality=high when file-type is photo even if user selects “normal”
Hi everyone, I observed a behavior with AirPrint from an iPhone and wanted to confirm if this is expected behavior from iOS. Scenario tested: File type: Photo Print-quality selected by the user: Normal Observation (from packet capture): When checking the PCAP for the request sent from the iPhone, the print-quality attribute is always sent as high, even though the user selected Normal in the UI. Question: Is this an expected behavior in iOS/AirPrint where photos are always sent with print-quality=high regardless of the user-selected print quality? Or could this be a bug?

Supported URL Schemes
Some Apple URL schemes are documented for third-party use. It’s fine to use those URL schemes for their intended purpose. Other Apple URL schemes are not officially documented. Their use is unsupported. If you rely on such implementation details, things might work, or they might not, and that state might change over time. IMPORTANT If you ship via the App Store, pay attention to clause 2.5.1 of the App Review Guidelines. The Apple URL scheme documentation is not always easy to find. I’m aware of the following: Apple URL Scheme Reference QA1924 Opening Keyboard Settings from a Keyboard Extension [This Q&A was retired years ago.] Preparing your app to be the default messaging app The doc comments for es_new_client in <EndpointSecurity/ESClient.h> Developer > Bug Reporting describes the applefeedback scheme Additionally, as questions about this most commonly crop up in the context of opening Settings (System Settings on macOS), I wanted to highlight the following: UIApplication.openSettingsURLString property (in Objective-C this is UIApplicationOpenSettingsURLString) UIApplication.openNotificationSettingsURLString property (in Objective-C this is UIApplicationOpenNotificationSettingsURLString) UIApplication.openDefaultApplicationsSettingsURLString property (in Objective-C this is UIApplicationOpenDefaultApplicationsSettingsURLString) AccessibilitySettings.openSettings(for:) method FIFinderSyncController.showExtensionManagementInterface() class method SMAppService.openSystemSettingsLoginItems() class method VSOpenTVProviderSettingsURLString global CXCallDirectoryManager.openSettings(completionHandler:) method SFSafariSettings.openExportBrowsingDataSettings() method SFSafariSettings.openExtensionsSettings(forIdentifiers:) method If your app needs to perform some action that’s not covered by the above, file an enhancement request for a supported way to do that.

UI Testing and 'Allow Paste'
I am developing an app that allows the user to ask it to process the clipboard contents and do something with it. In developing a XC UI Test, I find the app stops while it waits for the user to give permission. That breaks the automation. I tried: let springboard = XCUIApplication(bundleIdentifier: "com.apple.springboard") let allowButton = springboard.buttons["Allow Paste"] But that does not work. Is there a way to tell the framework to automatically give the test permission to access the Paste clipboard (or to allow me to write tests to grant this)?

LiveCommunicationKit
What I want to achieve now is that when the app is not running, upon receiving a notification, it displays an interface similar to CallKit with accept and decline buttons. Here is part of my code: @available(iOS 17.4, *) class LiveCommunicationManager: NSObject, ConversationManagerDelegate { static let shared = LiveCommunicationManager() var isInvalidate:Bool = false var configuration: ConversationManager! override init() { let config = ConversationManager.Configuration( ringtoneName: "notes_of_the_optimistic", iconTemplateImageData: UIImage(named: "AppIcon")?.pngData(), // 图标的 PNG 数据 maximumConversationGroups: 1, // 最大对话组数 maximumConversationsPerConversationGroup: 1, // 每个对话组内最大对话数 includesConversationInRecents: false, // 是否在通话记录中显示 supportsVideo: false, // 是否支持视频 supportedHandleTypes: [.generic,.phoneNumber,.emailAddress] // 支持的通话类型 ) configuration = ConversationManager.init(configuration: config) } func reportIncomingCall(uuid: UUID, callerName: String) { configuration.delegate = self let local = Handle(type: .generic, value: callerName, displayName: callerName) let update = Conversation.Update(localMember: local,members: [local],activeRemoteMembers: [local]) Task{ do { try await configuration.reportNewIncomingConversation(uuid: uuid, update: update) print("成功报告新来电") } catch { print("报告新来电失败: \(error.localizedDescription)") } } } func conversationManager(_ manager: ConversationManager, conversationChanged conversation: Conversation) { print("会话状态改变了") } func conversationManagerDidBegin(_ manager: ConversationManager) { print("会话已经开始了") manager.delegate = self } func conversationManagerDidReset(_ manager: ConversationManager) { print("会话将要清除了") } func conversationManager(_ manager: ConversationManager, perform action: ConversationAction) { print("会话接听了") configuration.invalidate() } func conversationManager(_ manager: ConversationManager, timedOutPerforming action: ConversationAction) { print("会话超时了") } func conversationManager(_ manager: ConversationManager, didActivate audioSession: AVAudioSession) { print("会话激活了") } func conversationManager(_ manager: ConversationManager, didDeactivate audioSession: AVAudioSession) { print("会话死亡了") } } 在Appdelegate里设置了这些: func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -&gt; Void) { // 在这里处理离线推送通知 completionHandler(.noData) // 返回后台任务完成 if let aps = userInfo["aps"] as? [String: Any], let alert = aps["alert"] as? [String : Any]{ // 静默推送的处理逻辑 if #available(iOS 17.4, *) { let manager = LiveCommunicationManager.shared if manager.isInvalidate { return } if let msgType = userInfo["msgType"] as? Int{ if msgType == 5{ manager.configuration.invalidate() }else{ let callerName = alert["title"] as? String ?? "Fanvil" manager.reportIncomingCall(uuid: UUID(), callerName: callerName) } } } } } Xcode has been configured with the necessary capabilities, such as Background Fetch, Voice over IP, Background Processing, and Push Notification. The issue now is that sometimes the code works as expected, allowing the app to wake up when not running and displaying the system interface with accept and decline buttons. However, after a few successful attempts, the app stops waking up, and no notification appears. But when I manually open the app, the didReceiveRemoteNotification method gets triggered. I’d like to know why this stops working after a few times.

CarPlay Simulator: How to Change Dock Position for Right-Hand Drive (RHD)
Hello everyone, I'm developing a CarPlay app and am trying to test it with the dock on the right side of the screen, as is standard for right-hand drive vehicles like those in Japan. Currently, the CarPlay Simulator always displays the dock on the left, and I can't find an option to change its position. This is important for ensuring a proper user experience for my target market. Has anyone figured out how to configure the simulator for RHD layouts? Any guidance on how to move the dock to the right would be greatly appreciated. Thanks in advance for your help!

USB Control Transfers on Devices with CDC Serial Port
I have a USB-device with three interfaces: Vendor-Specific Bulk CDC Serial Control CDC Serial Data To configure the vendor specific bulk endpoints I need to send vendor specific control requests to endpoint 0. I'm using libusb for this task. As long as the interfaces for the CDC serial port are present I get an access error when trying to send vendor control requests. If I disable these CDC interfaces I can send vendor control request without any problems: Is this by design or ist there any possibility to send vendor control requests to the USB device while a CDC driver is active?

Kext loads well after launchd and early os_log entries rarely appear in unified log
Is there a way to ensure a kernel extension in the Auxiliary Kernel Collection loads (and runs its start routines) before launchd? I'm emitting logs via os_log_t created with an os_log_create (custom subsystem/category) in both my KMOD's start function and the IOService::start() function. Those messages-- which both say "I've been run"-- inconsistently show up in log show --predicate 'subsystem == "com.bluefalconhd.pandora"' --last boot, which makes me think they are running very early. However, I also record timestamps (using mach_absolute_time, etc.) and expose them to user space through an IOExternalMethod. The results (for the most recent boot): hayes@fortis Pandora/tests main % build/pdtest Pandora Metadata: kmod_start_time: Time: 2025-07-22 14:11:32.233 Mach time: 245612546 Nanos since boot: 10233856083 (10.23 seconds) io_service_start_time: Time: 2025-07-22 14:11:32.233 Mach time: 245613641 Nanos since boot: 10233901708 (10.23 seconds) user_client_init_time: Time: 2025-07-22 14:21:42.561 Mach time: 14893478355 Nanos since boot: 620561598125 (620.56 seconds) hayes@fortis Pandora/tests main % ps -p 1 -o lstart= Tue Jul 22 14:11:27 2025 Everything in the kernel extension appears to be loading after launchd (PID 1) starts. Also, the kext isn't doing anything crazy which could cause that kind of delay. For reference, here's the Info.plist: <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>CFBundleExecutable</key> <string>Pandora</string> <key>CFBundleIdentifier</key> <string>com.bluefalconhd.Pandora</string> <key>CFBundleName</key> <string>Pandora</string> <key>CFBundlePackageType</key> <string>KEXT</string> <key>CFBundleVersion</key> <string>1.0.7</string> <key>IOKitPersonalities</key> <dict> <key>Pandora</key> <dict> <key>CFBundleIdentifier</key> <string>com.bluefalconhd.Pandora</string> <key>IOClass</key> <string>Pandora</string> <key>IOMatchCategory</key> <string>Pandora</string> <key>IOProviderClass</key> <string>IOResources</string> <key>IOResourceMatch</key> <string>IOKit</string> <key>IOUserClientClass</key> <string>PandoraUserClient</string> </dict> </dict> <key>OSBundleLibraries</key> <dict> <key>com.apple.kpi.dsep</key> <string>24.2.0</string> <key>com.apple.kpi.iokit</key> <string>24.2.0</string> <key>com.apple.kpi.libkern</key> <string>24.2.0</string> <key>com.apple.kpi.mach</key> <string>24.2.0</string> </dict> </dict> </plist> My questions are: A. Why don't the early logs (from KMOD's start function and IOService::start) consistently appear in the unified log, while logs later in IOExternalMethods do? B. How can I force this kext to load earlier-- ideally before launchd? Thanks in advance for any guidance!

Family Controls Approved for Main App but Not Extension – Blocking
Hi everyone, I’m developing a screen-time and focus app that uses Apple’s Family Controls framework to block distracting apps and reward users through a gamified experience. Apple approved Family Controls (Distribution) for the main app identifier, but they did not approve the required extension target (which implements DeviceActivityMonitor, required for the framework to function). Because of this, I can’t archive or upload the app to TestFlight — and I’ve been stuck in limbo for over 2 months. This is severely delaying my launch. The app works perfectly, but I can’t release it because the extension wasn’t included in the entitlement approval. Has anyone else run into this with Family Controls? Is there any known way to escalate or fast-track approval for additional app IDs or targets? Would really appreciate any help, advice, or hacks. 🙏 Thanks, Enzer

How does ageGates actually affect the returned age range?
I’m trying to fully understand the purpose of the ageGates parameter in the AgeRangeService.requestAgeRange API. The official documentation includes the following statement: “The system may return geo-specific age ranges that override your provided age gates based on the person’s location and applicable regulations. When geo-specific ranges are required, the returned age range reflects regulatory requirements rather than the bounds of your age gates.” Based on this, it seems that even if my app provides specific age thresholds through the ageGates parameter, the system may override those boundaries depending on regional laws or regulations, and return a completely different lowerBound / upperBound than what my age gates would suggest. My current understanding is: ageGates indicates the thresholds my app uses to define its internal feature tiers, but the actual age range returned by the OS is determined by legal or regional requirements (e.g., COPPA, GDPR-K, AADC, SB2420), meaning the returned age range may not align with the age ranges implied by my ageGates values. I’d like to confirm whether this interpretation is correct. Additionally, if different regions may produce different lowerBound / upperBound values due to regulatory requirements, then it seems that: developers shouldn’t rely on fixed age buckets, and instead must implement feature gating logic dynamically based on whatever age range the OS returns. So my questions are: Is my understanding correct that ageGates is simply a hint that describes my app’s tier thresholds, and the OS may override those boundaries to comply with local regulations? If lowerBound / upperBound can vary across regions, what is the recommended way for developers to design their feature-gating logic? Should we avoid hardcoded age buckets and instead build flexible logic that adapts to whatever range the OS returns? I’d appreciate clarification so I can design our age-based policies appropriately and in a regulation-compliant way.

How to identify which minor user's authorization has been revoked by the parent/guardian?
I followed the method outlined in Apple's documentation to test "Revocation of Consent." Our server received the notification sent by Apple, but the parsed data only contains the following content (some data has been modified for privacy, but the fields remain unchanged): { "receiptType": "Sandbox", "bundleId": "com.xxx.xxxxx", "receiptCreationDate": 1764932591296, "requestDate": 1764932591296, "originalPurchaseDate": 1375340400000, "originalApplicationVersion": "1.0", "appTransactionId": "705020051250081000", "originalPlatform": "iOS" } How can we identify that "a parent/guardian has revoked authorization for a specific user"? We are unable to determine which minor user should be restricted from using certain features of our app. I hope to receive a prompt response from Apple's technical experts! Thanks A Lot !

How to debug a CoreSpotlight extension?
My CoreSpotlight extension seems to exceed the 6 MB memory limit. What’s the best way to debug this? I've tried to attach the debugger on the Simulator but the extension seems to be never launched when I trigger the reindex from Developer settings. Is this supposed to work? On device, I am able to attach the debugger. However, I can neither transfer the debug session to Instruments, nor display the memory graph. So I've no idea how the memory is used. Any recommendations how to move forward? Is there a way to temporarily disable the memory limit since even with LLDB attached, the extension is killed.

NSURL +resourceValuesForKeys:fromBookmarkData: value always "file:///" for NSURLVolumeURLKey
I try saving the value of NSURLVolumeURLKey when creating a bookmark. When resolving the bookmark later I pass the bookmark data to +resourceValuesForKeys:fromBookmarkData: but always pull out "file:///" which is wrong. In contrast the value for NSURLVolumeURLForRemountingKey is properly saved and restored using the same method.

Opening two (or more files) with one dialog box (save panel)
I am slowly converting an Objective C with C program to Swift with C. All of my menus and dialog boxes are now in Swift, but files are still opened and closed in Objective C and C. The following code is Objective C and tries to open two files in the same directory with two related names after getting the base of the name from a Save Panel. The code you see was modified by ChatGPT 5.0, and similar code was modified by Claude. Both LLMs wrote code that failed because neither knows how to navigate Apple’s sandbox. Does anybody understand Apple’s sandbox? I eventually want to open more related files and do not want the user to have to click through multiple file dialog boxes. What is the best solution? Are the LLMs just not up to the task and there is a simple solution to the Objective C code? Is this easier in Swift? Other ideas? Thanks in advance for any help. (BOOL)setupOutputFilesWithBaseName:(NSString*)baseName { NSString *outFileNameStr = baseName; if (outFileNameStr == nil || [outFileNameStr length] == 0) { outFileNameStr = @"output"; } // Show ONE save panel for the base filename NSSavePanel *savePanel = [NSSavePanel savePanel]; [savePanel setMessage:@"Choose base name and location for output files\n(Two files will be created: one ending with 'Pkout', one with 'Freqout')"]; [savePanel setNameFieldStringValue:outFileNameStr]; if (directoryURL != nil) { [savePanel setDirectoryURL:directoryURL]; } if ([savePanel runModal] != NSModalResponseOK) { NSLog(@"User cancelled file selection"); return NO; } // Get the selected file URL - this gives us security access to the directory NSURL *baseFileURL = [savePanel URL]; // Get the directory - THIS is what we need for security scope NSURL *dirURL = [baseFileURL URLByDeletingLastPathComponent]; // Start accessing the DIRECTORY, not just the file BOOL didStartAccessing = [dirURL startAccessingSecurityScopedResource]; if (!didStartAccessing) { NSLog(@"Warning: Could not start security-scoped access to directory"); } NSString *baseFileName = [[baseFileURL lastPathComponent] stringByDeletingPathExtension]; NSString *extension = [baseFileURL pathExtension]; // Create the two file names with suffixes NSString *pkoutName = [baseFileName stringByAppendingString:@"Pkout"]; NSString *freqoutName = [baseFileName stringByAppendingString:@"Freqout"]; NSURL *pkoutURL = [dirURL URLByAppendingPathComponent:pkoutName]; NSURL *freqoutURL = [dirURL URLByAppendingPathComponent:freqoutName]; NSLog(@"Attempting to open: %@", [pkoutURL path]); NSLog(@"Attempting to open: %@", [freqoutURL path]); // Open the first file (Pkout) globalFpout = fopen([[pkoutURL path] UTF8String], "w+"); if (globalFpout == NULL) { int errnum = errno; NSLog(@"Error: Could not open Pkout file at %@", [pkoutURL path]); NSLog(@"Error code: %d - %s", errnum, strerror(errnum)); if (didStartAccessing) { [dirURL stopAccessingSecurityScopedResource]; } return NO; } NSLog(@":white_check_mark: Pkout file opened: %@", [pkoutURL path]); // Open the second file (Freqout) globalFpfrqout = fopen([[freqoutURL path] UTF8String], "w+"); if (globalFpfrqout == NULL) { int errnum = errno; NSLog(@"Error: Could not open Freqout file at %@", [freqoutURL path]); NSLog(@"Error code: %d - %s", errnum, strerror(errnum)); fclose(globalFpout); globalFpout = NULL; if (didStartAccessing) { [dirURL stopAccessingSecurityScopedResource]; } return NO; } NSLog(@":white_check_mark: Freqout file opened: %@", [freqoutURL path]); // Store the directory URL so we can stop accessing later secureDirectoryURL = dirURL; return YES; }

BLE Notification & Write Latency/Batching on iOS (vs Android) – CoreBluetooth Real-Time Question
I am using a Raspberry Pi 5 (BLE 5.0) to read sensor data and send it via D-Bus and BlueZ to a Flutter application (flutter_blue_plus) for both iOS and Android. The goal is to display these real-time sensor updates directly on the device. On Android, the data transmission is immediate and the real-time visualization is extremely smooth and fast. However, on iOS, both BLE write and notification commands appear with noticeable latency—not only in real-time displays, but also when comparing ordinary notification feedback between the Raspberry Pi terminal and the iOS app. It seems that iOS buffers several BLE packets internally and then dispatches them in batches, which always introduces an additional delay. Additional setup details: I sample and transmit data every 25ms, sending binary packets of 20 bytes (length shouldn’t be a limiting factor). On the iOS side I am using an iPhone 15 Pro with iOS 18.6.2 (BLE 5.3). The Raspberry Pi (using btmon for logging) confirms after connection setup that the connection interval is fixed at 30ms (and cannot be changed). I have tried sending BLE packets every 30ms so that exactly one packet arrives per interval, but this made no difference—the latency and batch delivery remain. Interestingly, faster transmission rates (e.g. sending every 10ms) make the real-time display look smoother on iOS, but the guaranteed overall system latency does not improve. Also these methods used: write-without-response, using app in release modus (no debugging) Is there anyone familiar with this problem or a potential solution? Or is iOS simply not optimized for true real-time BLE data streaming and visualization? Any pointers, technical insights or workarounds would be greatly appreciated.
