Greetings i have an app that uses three different SwiftData models and i want to know what is the best way to use the them accross the app. I though a centralized behaviour and i want to know if it a correct approach.First let's suppose that the first view of the app will load the three models using the @Enviroment that work with @Observation. Then to other views that add data to the swiftModels again with the @Environment. Another View that will use the swiftData models with graph and datas for average and min and max.Is this a corrent way? or i should use @Query in every view that i want and ModelContext when i add the data. @Observable class CentralizedDataModels { var firstDataModel: [FirstDataModel] = [] var secondDataModel: [SecondDataModel] = [] var thirdDataModel: [ThirdDataModel] = [] let context: ModelContext init(context:ModelContext) { self.context = context } }

We are working on the health related application and use apple health kit to sync the data from different devices like watches or ring. We are targeting oura ring to get sleep and other parameters data. We are able to sync the data from oura for all other parameters (like pulse, respiratory rate, blood pressure, etc..) other than sleep. Surprisingly, sleep data that comes through other devices is syncing as expected from the health kit. We are even getting the data which is added manually in health kit. The only sleep data not syncing is from oura. Can we get a document or any kind of help to sync the data from oura in to our application using health kit?

I have read all the information and forum posts about local network, such as TN3179, etc., and have added NSLocalNetworkUsageDescription, but it does not solve my problem. The problem I encountered is described as follows: Device: iOS18.1.1 Signing method: automatic Xcode debug directly runs, and the app can access 17.25.11.128 normally. However, relase run or packaged into adhoc installation, this IP cannot be accessed. There is a phenomenon that the app package of the App Store can also be used. Our test team has few iOS18+ devices, and internal testing is not possible. Please contact us as soon as possible, thank you. ======= 我已经了解了所有关于local network 相关的资料和论坛帖子，比如TN3179 等等， 已经添加了 NSLocalNetworkUsageDescription， 但是不解决我的问题。 我遇到的问题描述如下： 设备：iOS18.1.1 签名方式：自动 xcode debug 直接运行，app是可以正常访问17.25.11.128的。 但是 relase run 或者 打包成 adhoc 安装，就无法访问这个IP了。 有一个现象， App Store 的app包 也是可以的。 我们的测试团队，iOS18+的设备就没几个，还不能内部测试了。请尽快联系我们，谢谢。

Hello everyone, I’m working on an iOS app that uses the new DeviceActivity framework to monitor and report user screen‐time in an extension (DeviceActivityReportExtension). I need to persist my processed screen‐time data into a standalone SQLite database inside the extension, but I’m running into issues opening and writing to the database file. Here’s what I’ve tried so far: import UIKit import DeviceActivity import SQLite3 class DeviceActivityReportExtension: DeviceActivityReportExtension { private var db: OpaquePointer? override func didReceive(_ report: DeviceActivityReport) async { // 1. Construct path in app container: let containerURL = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "group.com.mycompany.myapp") let dbURL = containerURL?.appendingPathComponent("ScreenTimeReports.db") // 2. Open database: if sqlite3_open(dbURL?.path, &db) != SQLITE_OK { print("❌ Unable to open database at \(dbURL?.path ?? "unknown path")") return } defer { sqlite3_close(db) } // 3. Create table if needed: let createSQL = """ CREATE TABLE IF NOT EXISTS reports ( id INTEGER PRIMARY KEY AUTOINCREMENT, date TEXT, totalScreenTime DOUBLE ); """ if sqlite3_exec(db, createSQL, nil, nil, nil) != SQLITE_OK { print("❌ Could not create table: \(String(cString: sqlite3_errmsg(db)))") return } // 4. Insert data: let insertSQL = "INSERT INTO reports (date, totalScreenTime) VALUES (?, ?);" var stmt: OpaquePointer? if sqlite3_prepare_v2(db, insertSQL, -1, &stmt, nil) == SQLITE_OK { sqlite3_bind_text(stmt, 1, report.date.description, -1, nil) sqlite3_bind_double(stmt, 2, report.totalActivityDuration) if sqlite3_step(stmt) != SQLITE_DONE { print("❌ Insert failed: \(String(cString: sqlite3_errmsg(db)))") } } sqlite3_finalize(stmt) } } However: Path issues: The extension’s sandbox is separate from the app’s. I’m not sure if I can use the same App Group container, or if there’s a better location for an on‐extension database. Entitlements: I’ve added the App Group (group.com.mycompany.myapp) to both the main app and the extension, but the file never appears, and I still get “unable to open database” errors. My questions are: How do I correctly construct a file URL for an SQLite file in a DeviceActivityReportExtension? Is SQLite the recommended approach here, or is there a more “Apple-approved” pattern for writing data from a DeviceActivity extension? Any sample code snippets, pointers to relevant Apple documentation, or alternative approaches would be greatly appreciated!

My app requirement is to check that User is on call while doing transaction. If user on call then we need to show Caution alert. For this requirement we used CallKit to detect Call status and it's working fine but recently Apple has rejected the application because of Callkit that is banned in China. Could you please provide any solution to check the Call Status only.

I have an issue in my app, where the crashing frame is an assertionFailure in BackingData.set inside SwiftData framework. My own app doesn't appear until frame 14. I have no idea what causes this, or even how to create a reproducible project as this only happens on some devices. The frame prior to the assertionFailure is this: #1 (null) in BackingData.set(any:value:) () It seems like there is a backing data encoding happening in my Model class, and some value is causing it to fail. The model being accessed is through a relationship, and the frame in the app crashing is along the lines of Text(parent.child.name) Obviously, something is wrong in how I have made child, but the part that stand out to me is the assertionFailure in a release build

We are developing a service that uses the “More Frequent Updates” feature of Live Activities. I have a question regarding the push notification budget for Live Activities. According to the documentation and the following session: WWDC23 Session 10185 – “What’s New in ActivityKit” https://developer.apple.com/videos/play/wwdc2023/10185/ At 11:58, it is stated that there is no limit on the number of updates when using low priority (5). Could you confirm whether updates sent with low priority (5) are indeed not subject to the Live Activity push notification budget?

Hi everyone, I was following the Video Modernize PCI and SCSI drivers with DriverKit and the Document to implement UserMapHBAData(), and here’s my current implementation: // kern_return_t DRV_MAIN_CLASS_NAME::UserMapHBAData_Impl(uint32_t *uniqueTaskID) kern_return_t IMPL(DRV_MAIN_CLASS_NAME, UserMapHBAData) { Log("UserMapHBAData() - Start"); // Define the vm_page_size explicitly const uint32_t vm_page_size = 4096; kern_return_t ret; IOBufferMemoryDescriptor *buffer = nullptr; IOMemoryMap *memMap = nullptr; void *taskData = nullptr; // Create a buffer for HBA-specific task data ret = IOBufferMemoryDescriptor::Create(kIOMemoryDirectionOutIn, ivars->fTaskDataSize, vm_page_size, &buffer); __Require((kIOReturnSuccess == ret), Exit); // Map memory to the driver extension's memory space ret = buffer->CreateMapping(0, 0, 0, 0, 0, &memMap); __Require((kIOReturnSuccess == ret), Exit); // Retrieve mapped memory address taskData = reinterpret_cast<void *>(memMap->GetAddress()); __Require(taskData, Exit); // WARNING: Potential leak of an object stored into 'buffer' // WARNING: Potential leak of an object stored into 'memMap' // Assign a unique task ID ivars->fTaskID++; // ERROR: No member named 'fTaskID' in 'DriverKitAcxxx_IVars' ivars->fTaskArray[ivars->fTaskID] = taskData; *uniqueTaskID = ivars->fTaskID; Log("UserMapHBAData() - End"); return kIOReturnSuccess; Exit: // Cleanup in case of failure if (memMap) { memMap->free(); // Correct method for releasing memory maps } if (buffer) { buffer->free(); // Correct method for releasing buffer memory } LogErr("ret = 0x%0x", ret); Log("UserMapHBAData() - End"); return ret; } For reference, in KEXT, memory allocation is typically done using: IOBufferMemoryDescriptor *buffer = IOBufferMemoryDescriptor::inTaskWithOptions( kernel_task, // Task in which memory is allocated kIODirectionOutIn, // Direction (read/write) 1024, // Size of the buffer in bytes 4); // Alignment requirements However, after installing the dext, macOS hangs, and I have to do a hardware reset.

We are using consumable in-app purchases. Starting from May 27th, we began receiving refund callbacks with the notificationType set to ONE_TIME_CHARGE immediately after users successfully completed a payment. { "notificationType": "ONE_TIME_CHARGE", "signedPayload": "..." } During this period, we did not make any changes to our App release or server-side purchase handling logic. Could this issue result in actual refunds being processed? What steps should we take to resolve this issue? We also noticed in your changelog that a new notification type ONE_TIME_CHARGE has been introduced. Can we safely ignore callbacks with the ONE_TIME_CHARGE notification type without affecting refund processing or user experience?

I have a dext that creates a periodic timer on its own dispatch queue. The callback is declared as follows: virtual void HandleTimer( OSAction *action, uint64_t time ) TYPE(IOTimerDispatchSource::TimerOccurred); The timer is allocated as follows: CreateActionHandleTimer( size, &ivars->TimerHandler ); IODispatchQueue::Create( "TimerQueue", 0, 0, &ivars->TimerDispatchQueue ); IOTimerDispatchSource::Create( ivars->TimerDispatchQueue, &ivars->TimerDispatchSrc ); I can start up the timer and it works just fine. However, in my Stop() method, when trying to shut the timer down, I get an assertion in OSAction::Cancel() for TimerHandler: Assertion failed: (queue), function Cancel, file uioserver.cpp, line 4401. What does this assertion indicate or is the source code available? If so, where? I'm using macOS 15.5. Note I am attempting to cancel the handler after the dispatch source and queue are canceled and the cleanup methods have been called (which is working). But, cancelling TimerHandler first also asserts.

When accessing https://applepaydemo.apple.com/payment-request-api, the "Approve with Side Button" prompt is displayed, but it does not appear when using our test domain. I implemented the Payment Request API based on the sample source code from the following URL. On an iPhone device, the Apple Pay payment screen is displayed, but the "Approve with Side Button" icon below the amount does not appear, and instead a spinning loading icon is shown continuously.

Will the ES_EVENT_TYPE_NOTIFY_OPEN event be called back when the user has already returned es_respond_flags_result(client, msg, 0, false) in ES_EVENT_TYPE_AUTH_OPEN? I believe the ES_EVENT_TYPE_NOTIFY_OPEN event should not be triggered if the user has already denied the open operation in the ES_EVENT_TYPE_AUTH_OPEN response handler. However, during my testing, ES_EVENT_TYPE_NOTIFY_OPEN was still being called even after I blocked the open process. Is this behavior correct?

My app cannot be launched on some users' MacOS, it says "Library not loaded: /usr/lib/libc++.1.dylib". "exception" : {"codes":"0x0000000000000000, 0x0000000000000000","rawCodes":[0,0],"type":"EXC_CRASH","signal":"SIGABRT"}, "termination" : {"code":1,"flags":518,"namespace":"DYLD","indicator":"Library missing","details":["(terminated at launch; ignore backtrace)"],"reasons":["Library not loaded: \/usr\/lib\/libc++.1.dylib","Referenced from: &lt;E4CB6764-8CB9-32E9-881B-252E2F3E0C4B&gt; \/Applications\/myapp.app\/Contents\/MacOS\/myapp","Reason: tried: '\/System\/iOSSupport\/usr\/lib\/libc++.1.dylib' (no such file), '\/System\/Volumes\/Preboot\/Cryptexes\/OS\/System\/iOSSupport\/usr\/lib\/libc++.1.dylib' (no such file), '\/System\/iOSSupport\/usr\/lib\/libc++.1.dylib' (no such file, no dyld cache), '\/usr\/lib\/libc++.1.dylib' (no such file), '\/System\/Volumes\/Preboot\/Cryptexes\/OS\/usr\/lib\/libc++.1.dylib' (no such file), '\/usr\/lib\/libc++.1.dylib' (no such file, no dyld cache)"]}, User 1's environment: 2020 MacBook Air, M1, system version 15.4. User 2's environment: 2020 MacBook Pro, M1, system version: 15.5. I (and the people around me) cannot reproduce this problem. It can be reproduced on User 2's computer, but the performance is strange, sometimes good and sometimes bad. The app can be launched normally during the day, and it can also be launched normally after restarting the computer. But it cannot be launched from 21:00 to 22:00 at night, and the problem still exists even if the computer is restarted. After some searching, I suspect that there is a bug in the dynamic linker cache mechanism of MacOS, but we cannot confirm it. According to the official documentation: https://developer.apple.com/documentation/macos-release-notes/macos-big-sur-11_0_1-release-notes New in macOS Big Sur 11.0.1, the system ships with a built-in dynamic linker cache of all system-provided libraries. As part of this change, copies of dynamic libraries are no longer present on the filesystem. Code that attempts to check for dynamic library presence by looking for a file at a path or enumerating a directory will fail. Instead, check for library presence by attempting to dlopen() the path, which will correctly check for the library in the cache. (62986286) I also tried to manually copy libc++.1.dylib to the above path, but these paths are read-only, and files cannot be copied into them even if SIP is turned off. Is there any other way to fix or avoid this problem? Thank you. Other similar questions: https://developer.apple.com/forums/thread/756370 https://developer.apple.com/forums/thread/764824

Hi. If the app is in landscape only and when the SKStoreProductViewController is presented, the safeArea changes to what looks like a portrait mode safe area. When the SKStoreProductViewController is dismissed, the safeArea does NOT revert back to the original values. Is there a way to force the safeArea to "reset"? I've submitted some bug tickets through Apple Feedback but I haven't received any response about it. The below code will pop up the SKStoreProductViewController and if you have a UIView that is constrained to the safe area, then you can visibly notice that the safe area is changed and doesn't go back. I have tested this on iPhone 14 Pro, iPhone 15, and iPhone 16 Pro and in the Simulators. The incorrect behavior happens on those and probably more. Thanks. #import "ViewController.h" #import &amp;lt;StoreKit/StoreKit.h&amp;gt; @interface ViewController () @property (nonatomic, strong) SKStoreProductViewController *productViewController; @end @implementation ViewController - (IBAction)buttonTapped:(id)sender { self.productViewController = [[SKStoreProductViewController alloc] init]; NSDictionary *parameters = @{ @"id" : @"6443575749" }; [self.productViewController loadProductWithParameters:parameters completionBlock:^(BOOL result, NSError * _Nullable error) { [self presentViewController:self.productViewController animated:YES completion:^{ // presented // The panel that is constraint to the safe area visibly shows that the safe area is no longer correct. }]; }]; } @end

After logging in to the main App, turn on screen recording, then switch to the interface of another App to perform operations. After about ten-odd minutes, when returning to the main App, it was found that the app was forcefully quit by the system, and subsequent operations could not be carried out.

I try to refresh the SDP data for a Bluetooth device that has reconnected. So when I receive connect notification I call -[IOBluetoothDevice performSDPQuery:] passing object, that should receive the query completion call. What I observe is that sdpQueryComplete:status: is not being called, buit calling performSDPQuery causes additional connect notification to be dispatched. Running this under debugger results in some weird log line: [IOBluetooth] **** This currently won't trigger SDP delegate I run this code on Sequoia 15.5
