Overview

I have invested significant money building a proximity application that shows hotspots for nightlife, and also if there are other single people in the same vicinity. I have labeled it under Social Networking, but the app reviews have labeled me as a dating app and hit me with the 4.3 spam tag. My app has many unique features that don't exist with other apps, but because of the matching part of the app, I am SOL. I am waiting on an appeal, but based on what I have read, I will most likely be doomed. Talk about killing the American Dream and stifling innovation! What are my options? If I get 10K users testing it on Test Flight, will I have a better chance of getting approved? Has anyone been successful by offering an app through a developer's website?

Hi, I am developing an OpenType font with the following cursive feature. feature curs { lookup cursivejoinrtl; # RIGHT_TO_LEFT flag set between Hah, Meem, Yeh and final Meem lookup rehwawcursive; # RIGHT_TO_LEFT flag clear between Waw and Hah } curs; Here is the rendering of the word وحميم in TextEdit. Using HarfBuzz I got the following result. The same rendering problem occurs when using Safari. It seems that is related to Core Text. I reported the issue to Feedback Assistant over a year ago but haven't had a response yet. So I'm posting the problem on this forum. Any support on this matter would be greatly appreciated.

Hi all... The app I'm building is not really a beginner level test app, it's intended to be published so I want everything to be done properly while I'm both learning and building the app. I'm new to swift ecosystem but well experienced with python and JS ecosystems. These two models are causing my app to crash @Model final class CustomerModel { var id: String = UUID().uuidString var name: String = "" var email: String = "" var phone: String = "" var address: String = "" var city: String = "" var postalCode: String = "" var country: String = "" @Relationship(deleteRule: .nullify) var orders: [OrderModel]? @Relationship(deleteRule: .nullify) var invoices: [InvoiceModel]? init() {} } @Model final class OrderModel { var id: String = UUID().uuidString var total: Double = 0 var status: String = "processing" var tracking_id: String = "" var order_date: Date = Date.now var updated: Date = Date.now var delivery_date: Date? var active: Bool = true var createdAt: Date = Date.now var items: [OrderItem]? @Relationship(deleteRule: .nullify) var invoice: InvoiceModel? @Relationship(deleteRule: .nullify) var customer: CustomerModel? init() {} } both referenced in this model: @Model final class InvoiceModel{ var id: String = UUID().uuidString var status: String = "Pending" var comment: String = "" var dueDate: Date = Date.now var createdAt: Date = Date.now var updated: Date = Date.now var amount: Double = 0.0 var paymentTerms: String = "Once" var paymentMethod: String = "" var paymentDates: [Date] = [] var numOfPayments: Int = 1 @Relationship(deleteRule: .nullify, inverse: \OrderModel.invoice) var order: OrderModel? @Relationship(deleteRule: .nullify) var customer: CustomerModel? init() {} } This is my modelContainer in my index structure: @main struct Aje: App { var appContainer: ModelContainer = { let schema = Schema([UserModel.self, TaskModel.self, SubtaskModel.self, InventoryModel.self, SupplierModel.self]) let config = ModelConfiguration(schema: schema, isStoredInMemoryOnly: false, allowsSave: true, groupContainer: .automatic, cloudKitDatabase: .automatic) do{ return try ModelContainer(for: schema, configurations: [config]) }catch{ fatalError("An error has occured: \(error)") } }() var body: some Scene { WindowGroup { ContentView() } .modelContainer(appContainer) } } This works fine but the below after adding the problematic models crashes the app unless CloudKit is disabled @main struct Aje: App { var appContainer: ModelContainer = { let schema = Schema([UserModel.self, TaskModel.self, SubtaskModel.self, InventoryModel.self, SupplierModel.self, InvoiceModel.self, OrderModel.self, CustomerModel.self]) let config = ModelConfiguration(schema: schema, isStoredInMemoryOnly: false, allowsSave: true, groupContainer: .automatic, cloudKitDatabase: .automatic) do{ return try ModelContainer(for: schema, configurations: [config]) }catch{ fatalError("An error has occured: \(error)") } }() var body: some Scene { WindowGroup { ContentView() } .modelContainer(appContainer) } }

Hi all, We are migrating a SCSI HBA driver from KEXT to DriverKit (DEXT), with our DEXT inheriting from IOUserSCSIParallelInterfaceController. We've encountered a data corruption issue that is reliably reproducible under specific conditions and are hoping for some assistance from the community. Hardware and Driver Configuration: Controller: LSI 3108 DEXT Configuration: We are reporting our hardware limitations to the framework via the UserReportHBAConstraints function, with the following key settings: // UserReportHBAConstraints... addConstraint(kIOMaximumSegmentAddressableBitCountKey, 0x20); // 32-bit addConstraint(kIOMaximumSegmentCountWriteKey, 129); addConstraint(kIOMaximumByteCountWriteKey, 0x80000); // 512KB Observed Behavior: Direct I/O vs. Buffered I/O We've observed that the I/O behavior differs drastically depending on whether it goes through the system file cache: 1. Direct I/O (Bypassing System Cache) -> 100% Successful When we use fio with the direct=1 flag, our read/write and data verification tests pass perfectly for all file sizes, including 20GB+. 2. Buffered I/O (Using System Cache) -> 100% Failure at >128MB Whether we use the standard cp command or fio with the direct=1 option removed to simulate buffered I/O, we observe the exact same, clear failure threshold: Test Results: File sizes ≤ 128MB: Success. Data checksums match perfectly. File sizes ≥ 256MB: Failure. Checksums do not match, and the destination file is corrupted. Evidence of failure reproduced with fio (buffered_integrity_test.fio, with direct=1 removed): fio --size=128M buffered_integrity_test.fio -> Test Succeeded (err=0). fio --size=256M buffered_integrity_test.fio -> Test Failed (err=92), reporting the following error, which proves a data mismatch during the verification phase: verify: bad header ... at file ... offset 1048576, length 1048576 fio: ... error=Illegal byte sequence Our Analysis and Hypothesis The phenomenon of "Direct I/O succeeding while Buffered I/O fails" suggests the problem may be related to the cache synchronization mechanism at the end of the I/O process: Our UserProcessParallelTask_Impl function correctly handles READ and WRITE commands. When cp or fio (buffered) runs, the WRITE commands are successfully written to the LSI 3108 controller's onboard DRAM cache, and success is reported up the stack. At the end of the operation, to ensure data is flushed to disk, the macOS file system issues an fsync, which is ultimately translated into a SYNCHRONIZE CACHE SCSI command (Opcode 0x35 or 0x91) and sent to our UserProcessParallelTask_Impl. We hypothesize that our code may not be correctly identifying or handling this SYNCHRONIZE CACHE opcode. It might be reporting "success" up the stack without actually commanding the hardware to flush its cache to the physical disk. The OS receives this "success" status and assumes the operation is safely complete. In reality, however, the last batch of data remains only in the controller's volatile DRAM cache and is eventually lost. This results in an incomplete or incorrect file tail, and while the file size may be correct, the data checksum will inevitably fail. Summary Our DEXT driver performs correctly when handling Direct I/O but consistently fails with data corruption when handling Buffered I/O for files larger than 128MB. We can reliably reproduce this issue using fio with the direct=1 option removed. The root cause is very likely the improper handling of the SYNCHRONIZE CACHE command within our UserProcessParallelTask. P.S. This issue did not exist in the original KEXT version of the driver. We would appreciate any advice or guidance on this issue. Thank you.

I updated my project (a Swift-based Screen Saver) from Xcode 14 to 15, and while the project works fine, I'm seeing a bunch of warnings during the link phase like this: ld: warning: reexported library with install name '/System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/SpeechSynthesis.framework/Versions/A/SpeechSynthesis' found at '/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/SpeechSynthesis.framework/Versions/A/SpeechSynthesis.tbd' couldn't be matched with any parent library and will be linked directly Am I doing something wrong? Can I safely suppress these warnings?

Hello! Some colleagues and work on Jujutsu, a version control system compatible with git, and I think we've uncovered a potential lock contention bug in either APFS or the Darwin kernel. There are four contributing factors to us thinking this is related to APFS or the Kernel: jj's testsuite uses nextest, a test runner for Rust that spawns each individual test as a separate process. The testsuite slowed down by a factor of ~5x on macOS after jj started using fsync. The slowdown increases as additional cores are allocated. A similar slowdown did not occur on ext4. Similar performance issues were reported in the past by a former Mercurial maintainer: https://gregoryszorc.com/blog/2018/10/29/global-kernel-locks-in-apfs/. My friend and colleague André has measured the test suite on an M3 Ultra with both a ramdisk and a traditional SSD and produced this graph: (The most thorough writeup is the discussion on this pull request.) I know I should file a feedback/bug report, but before I do, I'm struggling with profiling and finding kernel/APFS frames in my profiles so that I can properly attribute the cause of this apparent lock contention. Naively, I ran xctrace record --template 'Time Profiler' --output output.trace --launch /Users/dbarsky/.cargo/bin/cargo-nextest nextest run, and while that detected all processes spawned by nextest, it didn't record all processes as part of the same inspectable profile and didn't really show any frames from the kernel/APFS—I had to select individual processes. So I don't waste people's time and so that I can point a frame/smoking gun in the right system, how can I can use instruments to profile where the kernel and/or APFS are spending its time? Do I need to disable SIP?

When I run my Mac Catalyst app I'm getting unacceptable performance when resizing the window. Window resizing is very unresponsive/laggy. Configuration: The root view controller is a UISplitViewController (three pane split using UISplitViewControllerStyleTripleColumn). Sidebar is configured. It's using a UICollectionView sidebar style (so it looks like NSOutlineView in AppKit). On initial launch there is no selection and the second and third view controllers in the split have empty placeholder view controllers. At this point window resizing is fine. Now I make a selection in the sidebar. This populates the supplementary view controller with a view controller that uses a UITableView. Now resizing the window performance is awful. Basically this is unusable. When resizing the window a bunch what looks to be Core Animation related logs flood the console during window resize: cannot add handler to 3 from 1 - dropping Library: QuartzCore | Subsystem: com.apple.coreanimation Now if I go to my app's Info.plist and add: UIDesignRequiresCompatibility entry with a value of TRUE and follow the same steps described above window resizing works as expected and I do not experience performance issues. Also with UIDesignRequiresCompatibility there is no "cannot add handlers" error logs flooding the console on window resize.

In the official explanation, "deployment targets" refers to "the OS range supported by this version of Xcode for uploading apps to App Store Connect." On the Xcode Support page (https://developer.apple.com/support/xcode/), I can find the deployment targets supported by each Xcode version. My question is: can I use a newer version of Xcode to build an IPA with an older deployment target that isn’t listed? For example, can I use Xcode 26 to build an iOS 12 IPA (just build, not debug)? In my opinion, since the new SDKs still contain many old macros restricted to earlier iOS versions, it should be possible, but I’m not sure if that’s correct. Thanks.

Hi all, I have set up a trivial test project to try Apple-hosted background assets following the instructions in the three articles at https://developer.apple.com/documentation/backgroundassets. When I run the local mock server with xcrun ba-serve and set the URL override in Settings as described in the "Testing asset packs locally" article, I am able to download a test pack on my iOS devices. On the Mac that I use to run the mock server, however, the same call to AssetPackManager.shared.assetPack(withID: "TestAssetPack") that works on iOS always reports The asset pack with the ID “TestAssetPack” couldn’t be looked up: No asset pack with the ID “TestAssetPack” was found. even when not running the mock server, which led me to believe that it may not be hitting it at all. In fact, the macOS app will download asset packs uploaded to App Store Connect even when running the local server and setting the xcrun ba-serve url-override to the exact same string as in Settings on iOS. My initial suspicion was that something is wrong with the URL override, so I have tried all combinations of the Mac's hostname, IP address or "localhost" (with the corresponding SSL certificates) with and without port 443, always prefixing with "https://" for the url-override. All the same. Does anyone have an idea what may be the issue here? My asset pack has the following manifest: { "assetPackID": "TestAssetPack", "downloadPolicy": { "onDemand": {} }, "fileSelectors": [ { "file": "TestAsset.txt" } ], "platforms": [ "iOS", "macOS" ] } I am running v26.1 for macOS, iOS & Xcode. Edit: Just to be clear, my assumption here is that the URL overrides (in Settings on iOS or via ba-serve on macOS) is what should cause the app to hit the mock server. Is that correct or am I missing something?

I am trying to create a new app using IOS-26.1, macOS Tahoe 26.1 and Xcode 26.1 with Swift6. Is this a bug that is going to be addressed. This is in the Debug Console...Unable to simultaneously satisfy constraints. Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) ( "<NSAutoresizingMaskLayoutConstraint:0x10bb18870 h=--& v=--& _TtCC5UIKit19NavigationButtonBar15ItemWrapperView:0x115da48c0.width == 0 (active)>", "<NSLayoutConstraint:0x115ac2ee0 _TtCC5UIKit19NavigationButtonBar15ItemWrapperView:0x115da48c0.leading == _UIButtonBarButton:0x115d40c80.leading (active)>", "<NSLayoutConstraint:0x115ac30c0 H:[_UIButtonBarButton:0x115d40c80]-(0)-| (active, names: '|':_TtCC5UIKit19NavigationButtonBar15ItemWrapperView:0x115da48c0 )>", "<NSLayoutConstraint:0x115ac2df0 'TB_Leading_Leading' H:|-(12)-[_UIModernBarButton:0x115d20a80] (active, names: '|':_UIButtonBarButton:0x115d40c80 )>", "<NSLayoutConstraint:0x115ac2fd0 'TB_Trailing_Trailing' H:[_UIModernBarButton:0x115d20a80]-(12)-| (active, names: '|':_UIButtonBarButton:0x115d40c80 )>" ) Will attempt to recover by breaking constraint <NSLayoutConstraint:0x115ac2fd0 'TB_Trailing_Trailing' H:[_UIModernBarButton:0x115d20a80]-(12)-| (active, names: '|':_UIButtonBarButton:0x115d40c80 )> Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger. The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.

When I tap on one of the buttons in the ShieldAction extension I want to close the shield and open the parent app instead of the shielded app. Is there any way of doing this using the Screen Time API? class ShieldActionExtension: ShieldActionDelegate {      override func handle(action: ShieldAction, for application: ApplicationToken, completionHandler: @escaping (ShieldActionResponse) -> Void) {     // Handle the action as needed.           let store = ManagedSettingsStore()               switch action {     case .primaryButtonPressed:       //TODO - open parent app       completionHandler(.defer)     case .secondaryButtonPressed:       //remove shield       store.shield.applications?.remove(application)       completionHandler(.defer)         @unknown default:       fatalError()     }   }   }

(I truly appreciate all the responses you all have written for me :bow: ) I was under the assumption that for Live Activity, in order for you to be able to update the Activity, you need an update token. And for the OS to issue you the update token, user must hit the "Allow" from the lock screen. However based on these screenshots it seems that you don't need to hit "Allow" to be able to update the Live Activity. Live Activity was updated — even without the user hitting "Allow" So now I'm wondering if: Is hitting Allow required for the update token to get issued? Or that assumption is incorrect? In our tests (when connected to Proxyman, the OS emits the update token after user hits "Allow" / "Always Allow") If you don't hit allow, are there alternate ways to update the Live Activity without having the update token? I'm guessing you could set a short stale time and then when the OS launches the app in the background you query the server and then update the Live Activity. Is that a worthy approach? I also noticed that the "The Philly Inquirer" App has 'Background App Refresh" enabled, but this happened in 2 minutes. In our architecture assessments, after reviewing Apple's docs on 'Background Processing", we didn't think of it as a viable option, because it can't guarantee if the OS is given time in the next 2 minutes or 10 hours later when the phone is getting charged again. Are any of these workarounds viable or are there alternate approaches? Our requirement is: be able to use Live Activity between 2-72hrs after app install. (I mention this because perhaps Apple may impost some restrictions for new installs) be able to update an active Live Activity within 1-2 minutes after it has began.

I am trying to migrate an app to use Network framework for p2p connection. I came across this great article for migrating to Network framework however this doesnt use the new structured concurrency. This being introduced with iOS 26, there doesnt seem to be any sample code available on how to use the new classes. I am particularly interested in code samples showing how to add TLS with PSK encryption support and handling of switching between Wifi and peer to peer interface with the new structured concurrency supported classes. Are there any good resources I can refer on this other than the WWDC video?

Previously I was able to "snapshot" view that were not part of any window hierarchy using the following: NSImage *buttonImage = [NSImage imageWithSystemSymbolName:@"49.circle.fill" accessibilityDescription:nil]; NSButton *aButton = [NSButton buttonWithImage:buttonImage target:nil action:nil]; [aButton sizeToFit]; NSBitmapImageRep *rep = [aButton bitmapImageRepForCachingDisplayInRect:aButton.bounds]; if (rep == nil) { NSLog(@"Failed to get bitmap image rep."); return; } [aButton cacheDisplayInRect:aButton.bounds toBitmapImageRep:rep]; NSData *tiffData = rep.TIFFRepresentation; NSImage *snapShotOfImage = [[NSImage alloc]initWithData:tiffData]; Now on macOS Tahoe I get a non nil image, but the image is blank. However if I add aButton NSWindow's view hiearchy just before the call to -cacheDisplayInRect:toBitmapImageRep: I do get a proper image. Is this behavior intended or is this considered a bug? Is it documented anywhere that a view must be in a NSWindow for -cacheDisplayInRect:toBitmapImageRep: to work? Thanks

My app (FindAnyFile) provides a Finder-like interface in which it also offers a QuickLook preview command, which invokes [[QLPreviewPanel sharedPreviewPanel] makeKeyAndOrderFront:nil]; Now, if it shows .abcdp files, it often, but not always, crashes. This has been happening for many macOS versions, at least since 10.15, up to 26.1. Also, it does not seem to matter which SDK/Xcode I build with, as I used several and all versions lead to the crash. The issue rather appears to be inside the QLplugin for the AB file (ABCardCollectionView etc.). I am able to trace this crash in Xcode. There are a LOT of errors and warnings coming up, and eventually the qlplugin throws an ObjC exception which in turn brings down my entire app (and here I thought that the XPC system was designed to expressly avoid such crashes). Possibly significant errors are: CNAccountCollectionUpdateWatcher 0x6000025cf800: Update event received, but store registration failed. This event will be handled, but the behavior is undefined. Error using remote object proxy when fetchAnonymousXPCEndpoint: Error Domain=NSCocoaErrorDomain Code=4097 "connection to service named com.apple.telephonyutilities.callservicesdaemon.callstatecontroller" UserInfo={NSDebugDescription=connection to service named com.apple.telephonyutilities.callservicesdaemon.callstatecontroller} connection to service named com.apple.coreduetd.people … CNPropertyNotFetchedException: A property was not requested when contact was fetched. I've attached the (mostly) complete console output from such a debug run. I have also an open bug report regarding this kind of crash (back then I was not able to reproduce it myself): FB15553847 Also, when I "Quick Look" the same file in Finder, I get a "Preview not permitted" for the same items that crash in my app. If I copy the same items to the Desktop, then Finder can QL them and my app doesn't crash when viewing the item on the Desktop. So, the crash only happens with the items inside ~/Library/Application Support/AddressBook/Sources/…/Metadata/. Now, here is the weirdest part: You might think: So, if the Finder shows "Preview not permitted", then my app trying to view those items is the result of that condition (even if that's not supposed to crash). However: I have a clean 26.1 install (in an Apple ARM VM) where Finder also says "Preview not permitted" for these items in the user's Library/AB/Metadata folder, but my app can QL those items without crashing! Also, I have one user who uses 26.1 and gets the crash with files in the same location. So, the "Preview not permitted" is probably not the cause of this crash, though it's suspicious that a user gets this at all - why can't a user QL the abcdp files in the Metadata folder but when copied to the Desktop, QL works? You'd think that Finder has the necessary entitlements to access the AB, or doesn't it? Of course, my app has permission enabled under Privacy & Security / Contacts (if it's disabled, then the app can't show anything but will also not crash). And it has the "Address Book" entitlement. Would be nice if this could be looked into and eventually be fixed. Alternatively, I'd welcome any suggestions on how to prevent my app from crashing if the qlplugin throws. But if you look at the stack trace you'll see that there's no method of my own app involved where I could insert an exception catcher. I added code to my previewItemURL delegate method to make sure the NSURL item is readable, and it is, even Of course, apart from the issue with .abcdp files, the QL operation in my app works flawlessly, i.e. I have never received any other crash reports relating to any other QL plugins.

Hi, I developed a Platform Single Sign-On extension and a corresponding extension for my IdP, which is Keycloak based. The code for both projects are here: https://github.com/unioslo/keycloak-psso-extension and https://github.com/unioslo/weblogin-mac-sso-extension I realized that, when using the Secure Enclave as the AuthenticationMethod, and according to Apple's documentation, the Extension doesn’t obtain fresh ID Tokens when they expire if the refresh token is still valid. When using password as the Authentication Method, it fetches new ID tokens when they expire, without prompting the user for credentials, by using the refresh token. My suggestion is that the same behavior should be implemented for Secure Enclave keys. The thing here is that usually, on OIDC flows, the ID/Access tokens are short-lived. It would make sense for the extension to provide fresh ID tokens. It doesn’t seem to make sense for me that, when using passwords, the extension would fetch these tokens, and not when having the Secure Enclave key. By not doing this, Apple almost forces the developer of an extension to fetch new ID tokens themselves, which doens’t make sense when it clearly provides fresh tokens when using passwords. It almost forces the developers to either implement that logic themselves, or to issue longer tokens, which is not so nice. How so you deal with this? Do you simply use the refresh token as an authentication token, or do you do some sort of manual refresh on the extension?

Hi, I am trying to add a custom (create) button next to the automatic "toggle sidebar" button in a NavigationSplitView. When the sidebar is collapsed that button should be displayed in a group with that automatic toggle button. Basically I want exact the same behaviour as in the Apple "Reminders" App. How could I archive that? Thanks for your help :-) Jan

On macOS Tahoe 26 activating GUI apps from command-line often fails. It launches the app but not brings to the foreground as expected. For example, running the following commands in Terminal is expected to launch Pages and bring it to the foreground. open /Applications/Pages.app or osascript -e `tell application "Pages" to activate` Moreover, they sometimes not return in Terminal. These commands worked as expected until macOS 15 but no more in macOS 26. The tricky part is that this failure doesn't happen 100% of the time; it occurs randomly. However, since multiple users of my app have reported the same symptoms, and I can reproduce it not only with my app but also with apps bundled to macOS, I don't believe this is an issue specific to my environment alone. I’ve already filed this issue: FB21087054 Open version: https://github.com/1024jp/AppleFeedback/issues/87 However, I’d like to know if any workaround exists or my understanding is wrong, especially for case with osascript.
