I have been using the basic NSPersistentContainer with 100k+ records for a while now with no issues. The database size can fluctuate a bit but on average it takes up about 22mb on device. When I switch the container to NSPersistentCloudKitContainer, I see a massive increase in size to ~150mb initially. As the sync engine uploads records to iCloud it has ballooned to over 600mb on device. On top of that, the user's iCloud usage in settings reports that it takes up 1.7gb in the cloud. I understand new tables are added and history tracking is enabled but the size increase seems a bit drastic. I'm not sure how we got from 22mb to 1.7gb with the exact same data. A few other things that are important to note: I import all the 100k+ records at once when testing the different containers. At the time of the initial import there is only 1 relation (an import group record) that all the records are attached to. I save the background context only once after all the records and the import group have been made and added to the context. After the initial import, some of these records may have a few new relations added to them over time. I suppose this could be causing some of the size increase, but its only about 20,000 records that are updated. None of the records include files/ large binary data. Most of the attributes are encrypted. I'm syncing to the dev iCloud environment. When I do make a change to a single attribute in a record, CloudKit reports that every attribute has been modified (not sure if this is normal or not ) Also, When syncing to a new device, the sync can take hours - days. I'm guessing it's having to sync both the new records and the changes, but it exponentially gets slower as more records are downloaded. The console will show syncing activity, but new records are being added at a slower rate as more records are added. After about 50k records, it grinds to a halt and while the console still shows sync activity, only about 100 records are added every hour. All this to say i'm very confused where these issues are coming from. I'm sure its a combination of how i've setup my code and the vast record count, record history, etc. If anyone has any ideas it would be much appreciated.

Hello, We have seen the following URL from one of our users when using Apple Pay http://cn-apple-pay-gateway.apple.com/ It appears to be from the China region. Do we need to add this URL to our trusted domains? A little more context, the user is located in the United States and users from China should not be accessing our site. Does this mean the users device is set to China as a region?

I'm attempting to migrate my app's Homescreen widget from using the old SiriKit Intent system to the new AppIntent system but running into an issue. This WWDC video is the main source of information I have been going off of. https://developer.apple.com/videos/play/tech-talks/10168/ The problem I'm having is no matter what config I try, as soon as I upgrade to the new app with the AppIntent Widget, all the current widgets on the homescreen stop working, and just show a black screen. Deleting and re-adding the widget to the homescreen from scratch works fine though. I found someone else with a similar issue here on the Apple developer forums, but it didn't look like there was much information or resolution. https://developer.apple.com/forums/thread/759751 https://feedbackassistant.apple.com/feedback/14678285 I used XCode's built in Intent migration UI to create the new CustomIntentMigratedAppIntent which should help migrate the old widgets to the new system. I also double-checked all the names and variable types, and the automatically generated file seems to be correct. I even went ahead and created a brand new empty app with the same app and extension bundle id, and made a hard coded widget which contains the migrated intents, just to make sure nothing in my widget or app code is wrong. And even with the empty app with hardcoded views, the widget is still dead after upgrading the app. It almost seems like the widget is getting disassociated from the app. Even though the app has a new name, the old widget will still show the old name, the widget also does not give any option to edit it, only delete it. And on the new app, I am able to attach my debugger to the widget extension process, but no code inside my timeline, intent, or entity seem to ever be called/run. I looked at the Console log while forcing a refresh of the widget, and I've attached the full logs here, and there is a lot in there about it refreshing widgets. SEE LOGS HERE: Tomer_Logs.txt But one line that stands out, is this error which appears every time the old widget is refreshed [com.shemeshapps.MinecraftServerStatus::com.shemeshapps.MinecraftServerStatus.MinecraftServerStatusHSWidget:MinecraftServerStatusHSWidget:-5734839072461827392] Reload failed; 0 retries remaining: ChronoCoreErrorDomain (1) Error Domain=ChronoCoreErrorDomain Code=1 "Unknown extension process" UserInfo={NSLocalizedDescription=Unknown extension process} Any help in greatly appreciated, Either issues you think might be causing this, or any tips on debugging further! Thanks! I've gone ahead and filled a Feedback, as well as submitted a DTS issue, as this is a release blocker. (The feedback contains the new and old project files to allow anyone to reproduce.)

The same macOS app is logged into the same iCloud account on two Macs. The apps on both devices can sync data with iCloud, but the data between them is isolated. When I was developing, I just enabled the CloudKit(SwiftData host in iCloud) capability and did not do anything special. I thought that the same app and the same iCloud account should sync the same data between different devices. Why is the cloud data on these two Macs isolated?

After adding a pass to the wallet and setting the relevantDate, it doesn't show a notification on the screen after the relevantDate has passed. How do we test the wallet notification for a pass?

Using the native email ios mail app iPhone 16 pro. When an email arrives the phone will ding or vibrate, but the message notification doesn't appear on lock screen. If you touch the screen from dim to wake then scroll up, the email notification does appear. If the phone is open the notification also appears at the top of screen as it's meant to do. This started yesterday with iOS 18.2 beta 1. It was not resolved with the new update.

Kindly suggest the best approach for the below requirement. Requirement Summary: I have a camera that generates its own Wi-Fi network with some specifications, and I need my iOS app to automatically connect to that Wi-Fi whenever it's in range. This Wi-Fi network is used for transferring files between the camera and the iOS app and to give commands to camera to do certain actions. This Wi-Fi does not provide internet access. Details: The iOS app should automatically connect to the camera's Wi-Fi network once it launches. The camera's Wi-Fi does not have internet access; it is purely for file transfers (e.g., photos/videos) between the camera and the iOS app and to command camera to do certain actions The iOS device should still use mobile data for internet access while connected to the camera's Wi-Fi. The mobile data will be used to upload files to the cloud, as I have a large data plan available for internet use. The app should maintain the connection to the camera's Wi-Fi as long as the iOS device is within proximity of the camera. If the device moves out of range and then comes back, the iOS app should prefer and reconnect to the camera's Wi-Fi over any other available networks. I am looking for a solution or approach that can make this seamless, ensuring a stable connection between the camera and the iOS app while prioritizing mobile data for internet connectivity.

I have implemented push provisioning, but I’ve encountered issues while testing it. I have tried with builds both in Xcode and TestFlight. According to the sysdiagnose, I can see the following: { statusCode = 500; statusMessage = 'Broker Service Response exception'; } I reported the error in Feedback Assistant: ID: FB15689064 (Error during the In-App Provisioning process)

I have a CKRecord that references an CKAsset. If I understand it correctly, CKSyncEngine would download the asset every time the record has changed on the server. (Of course it would try to use the local asset cache, but worst-case it might be already flushed) The documentation for CKAsset says that asset downloads can be prevented by limiting the requested record keys using the desiredKeys property on the fetch operation. But I don't see any possibility to set this property when using CKSyncEngine. Did I miss something? Are there any alternatives?

Hello, I would like to check with you on a possible APNS issue. We saw a huge spike in the number of failed requests towards APNS (both api.push.apple.com and api.development.push.apple.com). On October 31st, at 13:39 (during 1 or 2 minutes), more than 700k requests failed. Which means more than 10% of all requests made by our service to api.push.apple.com. Our service is sending notification requests for more applications, different AppIds, in high amounts. Even more concerning is the fact that it happens more or less regularly now. 2-3 times a week. Still, just for short time, but I would like to check with APNS, whether it is something you know about. Checking graphs in CloudKit did not help me much. They don't allow good enough granularity. Not more precise than 1 day. Please, let me know if you are aware of some very short transient issues in APNS. Happening more or less regularly, with noticeable impact.

Hi, I made an earier post about this and unfortunately can’t locate it so I’m doing a new one with screenshots. After I click on the Done button, I can briefly see it already residing on my phone. Please see the attached photos. Is this normal? I have a iPhone 15 ProMax. Thank you, D

trying to quit 2 apps and launch a 3rd. 3 individual Automator apps work by themselves fine. But can't get them to "open an app" from Calendar at a specified time. Tried building an Apple Script. Same issue. Here's the Automator app. ** tell application "Jellyfin Media Player" to quit delay 1 tell application "Jellyfin server 10.10.1" to quit delay 1 tell application "EmbyServer 4.8.10" to activate** any help on what I'm doing wrong? seems simple enough. Both Automator and Script Ed have "full disk access" and "Accessibility"

Hello. My project includes a widget target that provides interactive widget functionalities. The document "Adding Interactivity to Widgets and Live Activities" says the following: Additionally, note that the perform() function is marked as throws. Be sure to handle errors instead of rethrowing them, and update your app, widget, and Live Activity as needed. For example, update a widget’s interface to indicate that it displays outdated information if it cannot load new data. https://developer.apple.com/documentation/widgetkit/adding-interactivity-to-widgets-and-live-activities#Implement-the-perform-function, column 3 However, I couldn't find a way how to handle an error in an interactive widget. The Button(intent:) and Toggle(intent:) initializers don't have mechanisms for error handling. Does anyone know a solution for handling errors in interactive widgets?

I've created a font family, but Font Book refuses to include it in the English language set, despite my best efforts. The font has every glyph in the OpenType "Std" set, plus several others. I've checked various boxes for Latin 1 and Macintosh Character Codepages; plus Unicode ranges for Basic Latin, additional Latin, etc, etc. I've compared it to several other fonts that are in the English set, and I can't see anything that they have that my fonts don't. (In fact, many of them seem to have much less!) I've created other fonts that are in the English set, but I've no idea what the difference is. Given that macOS relies on these Language sets, in order to hide the thousands of unnecessary fonts that are permanently installed in the OS, there ought to be some guidance on how to do this.

I am planning to implement Peer to Peer data exchange between 2 iOS devices. I have the following queries. My devices are connected through Ethernet. I would prefer to use this route if possible before switching over to Wifi. I can see there is an option to use prohibitedInterfaceTypes but that doesn't guarantee the route to use Ethernet when there are multiple available. Does the connection automatically switch between ethernet and Wifi or does that have to be handled via isViable and betterPathAvailable? I'm unsure when I should be using a custom framing protocol. I just need to exchange codable objects between the devices. Is the custom protocol required only if I use TCP as the underlying protocol? Can NSURLSessionStreamTask be used for this use case?

Ex Windows programmer trying to evolve to Mac... please go easy. :-) As part of my transition I'm trying to get some older stuff I wrote for myself to work. I have a command line utility program which uses socket(), connect(), send(), select/recv() to create a RAW socket and send a ICMP_ECHO packet to a host and then await its return. Essentially, PING with some minor variation in its output. Got it built in Xcode. Found that socket() with SOCK_RAW failed until I ran as root (via SUDO). OK, no problem. Now it sends, but it never receives a response. The select() always times out rather than receiving the reply. When I run my Windows cmd line version on the same machine under Parallels, it works fine. So I'm confident the other host is able to be reached from my network, etc. I can use actual PING from the command line just fine too. Is there some other permission facility in MacOS that would prevent me from receiving the reply packets? What would it be called, how would I either turn it off or work with it? Thanks for any help!

I was experimenting with Service Management API and Xcode project from https://developer.apple.com/documentation/servicemanagement/updating-your-app-package-installer-to-use-the-new-service-management-api and faced some issues with the API. I replaced agent with XPC service and tried to re-register it. Use case is a new app package installation with a newer service binary. In order to get the running service restarted with the new binary it's required to unregister old version and register new one. Otherwise the old version would be still running after app upgrade. The problem is that register fails with "Operation not permitted" error after running unregister which seems to work fine. Experiments with some delays (500ms) between unregister and register seem to help but it's a not a good solution to work around the problem. I'm using open func unregister() async throws with description: The completion handler will be invoked after the running process has been killed if successful or will be invoked whenever an error occurs. After the completion handler has been invoked it is safe to re-register the service. Sample output with no 500ms sleep between unregister and register calls: /Library/Application\ Support/YourDeveloperName/SMAppServiceSampleCode.app/Contents/MacOS/SMAppServiceSampleCode unregister && /Library/Application\ Support/YourDeveloperName/SMAppServiceSampleCode.app/Contents/MacOS/SMAppServiceSampleCode register Successfully unregistered LaunchDaemon(com.xpc.example.service.plist) Unable to register LaunchDaemon(com.xpc.example.service.plist): Error Domain=SMAppServiceErrorDomain Code=1 "Operation not permitted" UserInfo={NSLocalizedFailureReason=Operation not permitted} In fact it doesn't seem to be safe to re-register. Any explanation would much appreciated! ===================================================== Side issue #2: I tried to add a similar helper executable as in the original project with register/unregister and put it inside the same app bundle but at a different location like Contents/Helpers/ folder instead of Contents/MacOS. And it always fails with this error: Error Domain=SMAppServiceErrorDomain Code=3 "Codesigning failure loading plist: com.okta.service.osquery code: -67028" UserInfo={NSLocalizedFailureReason=Codesigning failure loading plist: com.okta.service.osquery code: -67028} When I moved the helper binary to Contents/MacOS/ folder along with the main app executable it starts working fine again. Other folders like Resources/XPCServices also don't work. Is it a hard requirement for an executable to be located inside main Contents/MacOS folder in order to be able to call SMAppService register/unregister APIs? I haven't found any documentation regarding this requirement. Thanks, Pavel

Is it possible to build an iOS app with the purpose of content filtering? I'll give an example. This app would block access to example.com, therefore if I were on the Safari or any iOS compatible browser, if I were to try to navigate to example.com access would be blocked. The same would happen if I were on let's say Instagram and it attempted to make an outbound api call to example.com, that too would fail. Is this device wide content filtering possible on the iOS platform? Furthermore would you be able to implement redirect logic. As in the user tries to visit example.com but it is redirected to google.com?

Hello all, I have a question, I am developing an application that uses the apply() function of the NEHotspotConfigurationManager class to switch the Wifi of the device. In the completionHandler of the apply() function, the error argument contains “Internal Error(8)” and the wifi switching may fail. We have never seen this problem during development, and since it occurs only in the market, we are at a loss as to the cause and countermeasure. Do you know the cause of the “Internal Error(8)” and how to fix it? A similar phenomenon has already been discussed in the following thread, but after countermeasures were taken in iOS12, it also occurs in iOS13 and later and no progress has been made since then. https://developer.apple.com/forums/thread/107851 I would appreciate it if someone could clarify what is happening with this error, as there is not much information on the web regarding this error. Thank you in advance.

Hello In the past, the documentation and specifically design guidelines were quite clear about the fact that having an exit button was not a good thing, and programmatically exiting the app was prohibited and ground to rejection by the review team. Looking though the documentation and guidelines nowadays, I cannot find any explicit mention of this. We have a client that want us to add such button on the main menu of an app, and we are looking to hard evidence that this is against standards. Has Apple stance on this changed ? Or have I missed it in the doc somewhere ?
