Overview

We use File Provider Extension in our main app, and it is working fine. We always call "NSFileProviderManager.add(_:completionHandler:)" function to start the extension, and "NSFileProviderManager.disconnect(reason:options:completionHandler:)" to temporarily quit the extension with the reason which will be shown in the Finder at the top of the FP domain folder. But sometimes, when the main app calls the above functions, the following issue cases occur, and the extension does not start/stop: The completionHandler function doesn't get called (As we noticed, we waited for 2 minutes. Then, we restarted the main app.) One of the following errors returned: i) "The application cannot be used right now", ii) "Couldn't communicate with the helper application", iii) "No valid file provider found with identifier" Here, the important thing is that restarting the main app once or twice clears the issue, and the extension starts. But it is frustrating to restart the app each time we get this issue. We want to know the following things: Why and when do the above issues occur? Why do they occur only sometimes, and how does the app restart clear the issue? How do we resolve them without restarting the main app? This has become a critical issue, so a detailed explanation would be greatly appreciated. TIA.

Dear Reviewers/Apple Team/Community, We have trying to submit our app continuously for review and being rejected continuously by Apple. Our app works perfectly fine in TestFlight using the same ID apple is using. We have also provided recorded video of the testing in TestFlight to Apple reviewer. However, despite our requests below things are not done: Before testing the in-app purchase subscription are not being approved, despite us requesting the same every time during submissions. At times we are getting snapshots under error category, where everything is correct even from Apple testing. We have no other way but to explain, give snapshots, give videos to Apple to help them understand how to test the app. We have requested the reviewers multiple times for a call, but we got a call only 1 time. We are not sure what is the way we can get to talk with the reviewer and understand from them the issue they are facing. Can anyone please help us out? Below is one example, it was given it us under error category, where even with apple standard, the purchase is successful. Can someone help us out plz.

Strangely today, I suddenly found I was unable to submit a new build of my iOS app to the app store. It builds perfectly well in Xcode Cloud, launches from TestFlight without issue, but when attempting to submit the app for App Review, I get this error: "This build is using a beta version of Xcode and can’t be submitted." Of course, the version of Xcode I'm using is not Beta - and I tried this on both public releases of Xcode 16.1 and Xcode 16.2. Has anyone else seen this, and if so, did you figure out a workaround?

Hello Apple engineers, could you help me understand whether this crash is a UIKit bug or something in our code that causes it. Based on the documentation it is an invalid fetch instruction, that's why I suspect UIKit. I've found a similar crash here on the forums reported a year ago, it seemed to be a UIKit bug - https://forums.developer.apple.com/forums/thread/729448. I've attached the full crash report (the app name was replaced with ): Thread 0 Crashed: 0 libobjc.A.dylib 0x000000019daf7c20 objc_msgSend + 32 (:-1) 1 UIKitCore 0x00000001a3020c50 -[UIView _wrappedProcessTraitChanges:withBehavior:] + 1288 (UIView.m:0) 2 UIKitCore 0x00000001a3020720 -[UIView _processChangesFromOldTraits:toCurrentTraits:withBehavior:] + 196 (UIView.m:7840) 3 UIKitCore 0x00000001a3020618 -[UIView _updateTraitCollectionAndProcessChangesWithBehavior:previousCollection:] + 112 (UIView.m:7831) 4 UIKitCore 0x00000001a2fa90c0 -[UIView(CALayerDelegate) layoutSublayersOfLayer:] + 944 (UIView.m:19850) 5 QuartzCore 0x00000001a22dfc28 CA::Layer::layout_if_needed(CA::Transaction*) + 496 (CALayer.mm:10944) 6 QuartzCore 0x00000001a22df7b4 CA::Layer::layout_and_display_if_needed(CA::Transaction*) + 148 (CALayer.mm:2638) 7 QuartzCore 0x00000001a2336914 CA::Context::commit_transaction(CA::Transaction*, double, double*) + 472 (CAContextInternal.mm:2613) 8 QuartzCore 0x00000001a22b57c4 CA::Transaction::commit() + 648 (CATransactionInternal.mm:420) 9 QuartzCore 0x00000001a22f8a0c CA::Transaction::flush_as_runloop_observer(bool) + 88 (CATransactionInternal.mm:928) 10 UIKitCore 0x00000001a303f568 _UIApplicationFlushCATransaction + 52 (UIApplication.m:3326) 11 UIKitCore 0x00000001a303cb64 __setupUpdateSequence_block_invoke_2 + 332 (_UIUpdateScheduler.m:1652) 12 UIKitCore 0x00000001a303c9d8 _UIUpdateSequenceRun + 84 (_UIUpdateSequence.mm:136) 13 UIKitCore 0x00000001a303c628 schedulerStepScheduledMainSection + 172 (_UIUpdateScheduler.m:1171) 14 UIKitCore 0x00000001a303d59c runloopSourceCallback + 92 (_UIUpdateScheduler.m:1334) 15 CoreFoundation 0x00000001a080c328 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__ + 28 (CFRunLoop.c:1970) 16 CoreFoundation 0x00000001a080c2bc __CFRunLoopDoSource0 + 176 (CFRunLoop.c:2014) 17 CoreFoundation 0x00000001a0809dc0 __CFRunLoopDoSources0 + 244 (CFRunLoop.c:2051) 18 CoreFoundation 0x00000001a0808fbc __CFRunLoopRun + 840 (CFRunLoop.c:2969) 19 CoreFoundation 0x00000001a0808830 CFRunLoopRunSpecific + 588 (CFRunLoop.c:3434) 20 GraphicsServices 0x00000001ec7e81c4 GSEventRunModal + 164 (GSEvent.c:2196) 21 UIKitCore 0x00000001a336eeb0 -[UIApplication _run] + 816 (UIApplication.m:3844) 22 UIKitCore 0x00000001a341d5b4 UIApplicationMain + 340 (UIApplication.m:5496) 23 UIKitCore 0x00000001a3757fa8 UIApplicationMain(_:_:_:_:) + 104 (UIKit.swift:565) 24 <Redacted> 0x00000001028bde64 specialized static UIApplicationDelegate.main() + 28 (/<compiler-generated>:16) 25 <Redacted> 0x00000001028bde64 static AppDelegate.$main() + 28 (AppDelegate.swift:0) 26 <Redacted> 0x00000001028bde64 main + 116 27 dyld 0x00000001c61f6ec8 start + 2724 (dyldMain.cpp:1334) 2024-12-27_20-53-28.2129_-0500-353aaa194e6232c0d1fae767296bdb8c47c30498.crash

Hello, I have an app on the App Store built around WeatherKit and it was working fine, up until this morning when I started seeing errors when using the app. When debugging using Xcode I see the familiar error Failed to generate jwt token for: com.apple.weatherkit.authservice with error: Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)" which, according to what I've read on the forums looks like an authentication error. Attaching a network debugger to the Simulator, I saw this error: This I have tried: Verify that WeatherKit is enabled on both Capabilities and App Services tabs on the Dev Portal. Toggle on/off this value and regenerate Provisioning Profiles Uninstall/reinstall Checking that I have API available calls. Nothing. If I create a new Bundle ID and sign with that, it works correctly. But this is not an option since that will force all my customers to download everything from scratch. I am getting emails from customers demanding money back and I can't figure out what has happened. The only thing I can think of, is that I started developing an Apple Watch app to complement the iOS app, but that was last week and everything was working fine.

I'm preparing my submission for the Swift Student Challenge, and I have a couple of questions regarding the development environment. Is it allowed to use Xcode to program my scene, or do I have to use Swift Playgrounds? Can I use iPadOS 18 for development? I noticed that Swift Playgrounds currently only supports up to iPadOS 17.5, but I would like to use RealityView, which is only available starting from iPadOS 18. I appreciate any clarification on this. Thanks in advance!

I am developing an iOS application that supports screen mirroring to Google TV (or Chromecast with Google TV). My goal is to mirror the iPhone/iPad screen in real time to a Google TV device. What I Have Tried So Far I have explored multiple approaches but haven't found a direct way to achieve low-latency screen mirroring. Here are some of my findings: Google Cast SDK: Google Cast SDK is primarily designed for casting media (videos, images, audio) rather than real-time mirroring. It supports custom receiver applications, but there are no direct APIs for full screen mirroring. Casting a recorded video is possible, but it introduces latency and is not real-time. ReplayKit for Screen Capture: RPScreenRecorder.shared().startCapture(handler: ...) allows capturing the iPhone screen as a video stream. However, sending this stream to Google TV in real time is a challenge. I could potentially encode the video as HLS and stream it, but the delay is significant. RTSP/UDP Streaming: Some third-party libraries support RTSP/UDP streaming for real-time screen sharing. Google TV does not natively support RTSP, making this approach difficult. My Questions: Is it possible to achieve real-time screen mirroring on Google TV using Google Cast SDK? Does Google TV support WebRTC or any low-latency streaming protocol that can be used from iOS? Are there any alternative approaches to mirror an iOS screen to Google TV with minimal latency? I would appreciate any guidance, code examples, or references to relevant documentation.

I am setting up a new app and am having problems with Xcode Cloud. From Xcode if I click on the "Cloud" button under the Report Navigator I get a spinner for a long time then get the message "Could not load Xcode Cloud data". I also visited the "Xcode Cloud" tab under my app in App Store Connect and I get a spinner and nothing loads. This is a recent account and I'm setting up Xcode Cloud for the first time. Below is what I've tried and I'm out of ideas on how to get this working. In Xcode, I signed out and back in as the Account Holder Closed Xcode and reopened This occurred yesterday and today and have not seen a problem under the Apple System Status page On the latest Xcode 16.2 Checked the Signing & Capabilities tab in Xcode and my team a bundle Id is correct and it's happy with signing. At this time on my machine I am using the distribution profile.

Hi everyone, I'm currently working on a Swift Playgrounds project where I need to incorporate a Metal shader file. However, when I tried to include my shader file (PincushionShader.metal), I encountered the following error: Is it possible to use Metal shader files within Swift Playgrounds, it is really important for my swift student challenge scene? If not, are there any workarounds or recommended approaches for testing Metal shaders in a similar environment? Any guidance or suggestions would be greatly appreciated!

Hey there, I'm building a service that requires receiving accurate app downloads and sales/proceeds data along with the campaign name. From reading the documentation it looks to be fairly understandable, but in practice it is not that straightforward. For example, I received the first one-time-snapshot detailed report for the App Store Purchases, and it contains partial data for several days. Shouldn't that be a full report of everything in analytics for like last year or so? Should I expect it to be updated and extended in the coming days? For the ongoing detailed report, I have not received anything yet, but I'm afraid it might have partial data as well. I will report here as well.

Hey there, I'm building a service that requires receiving accurate sales/proceeds data along with the campaign name. From reading the documentation it looks to be fairly understandable, but in practice it is not. I have been testing this for almost a week, and I never got "Detailed Report" for "App Store Purchases Detailed" analytics report. The same report for "App Downloads Detailed" is arriving normally, but not to for the purchases. I tested for two different apps where I have around 200 daily installs and 30 purchases on each. I would love to get any thoughts on this from an Apple engineer!

When logging into appstoreconnect I get the option to use a password or passkey: Password works fine. However passkey always results in: This is probably because I don't actually have any passkeys: So I think what is happening is that Apple thinks I have a passkey, which is why it's offering that as an option. I can't see any option to create a passkey, or regenerate one. I'm not sure how I've ended up in this state. I have a vague memory that sometime years ago when passkeys were first introduced on appstoreconnect that I tried to create one, but because it wouldn't let me store it in BitWarden, I backed out. It's not a major problem because I can still log in using password. But I'm worried in case some time in the future passkey becomes the only option. Does anyone know of any way I can reset or regenerate my passkey for appstoreconnect?

I'm trying to use ThreadNetwork API to manage TheradNetworks on device (following this documentation: https://developer.apple.com/documentation/threadnetwork/), but while some functions on THClient work (such as getPreferedNetwork), most don't (storeCredentials, retrieveAllCredentials).

Hi, We’ve been successfully using the RoomPlan API in our application for over two years. Recently, however, users have reported encountering persistent capture errors during their sessions. Specifically, the errors observed are: CaptureError.worldTrackingFailure CaptureError.exceedSceneSizeLimit What we have observed: Persistent Errors: The errors continue to occur even after initiating new capture sessions. Normal Usage: Our implementation adheres to typical usage patterns of the RoomPlan API without exceeding any documented room size limits. Limited Feature Usage: We are not utilizing the WorldTracking feature for the StructureBuilder functionality to stitch rooms together. Potential State Caching: Given that these errors persist across sessions, we suspect that there might be memory or state cached between sessions that is not being cleared, particularly since we are not taking advantage of StructureBuilder. Request: Could you please advise if there is any internal caching or memory retention between capture sessions that might lead to these errors? Additionally, we would appreciate guidance on how to clear or manage this state when the StructureBuilder feature is not in use. Here is a generalised version of our capture session initialization code to help diagnose the issue. struct RoomARCaptureView: UIViewRepresentable { typealias Handler = (CapturedRoom, Error?) -> Void @Binding var stop: Bool @Binding var done: Bool let completion: Handler? func makeUIView(context: Self.Context) -> RoomCaptureView { let view = RoomCaptureView(frame: .zero) view.delegate = context.coordinator view.captureSession.run(configuration: .init()) return view } func updateUIView(_ uiView: RoomCaptureView, context: Self.Context) { if stop { // Stop the session only once, multiple times causes issues with the final presentation uiView.captureSession.stop() stop = false done = true } } static func dismantleUIView(_ uiView: RoomCaptureView, coordinator: Self.Coordinator) { uiView.captureSession.stop() } func makeCoordinator() -> ARViewCoordinator { ARViewCoordinator(completion) } @objc(ARViewCoordinator) class ARViewCoordinator: NSObject, RoomCaptureViewDelegate { var completion: Handler? public required init?(coder: NSCoder) {} public func encode(with coder: NSCoder) {} public init(_ completion: Handler?) { super.init() self.completion = completion } public func captureView(shouldPresent roomDataForProcessing: CapturedRoomData, error: (Error)?) -> Bool { return true } public func captureView(didPresent processedResult: CapturedRoom, error: (Error)?) { completion?(processedResult, error) } } } Thank you for your assistance.

There seems to be a problem to a specific Apple Developer Account regarding Xcode Cloud Distribution (Signing). The Xcode Cloud Error Invalid Signature. Code failed to satisfy specified code requirement(s). The file at path “XcodeCloudTest.app/XcodeCloudTest” is not properly signed. Make sure you have signed your application with a distribution certificate, not an ad hoc certificate or a development certificate. Verify that the code signing settings in Xcode are correct at the target level (which override any values at the project level). Additionally, make sure the bundle you are uploading was built using a Release target in Xcode, not a Simulator target. If you are certain your code signing settings are correct, choose “Clean All” in Xcode, delete the “build” directory in the Finder, and rebuild your release target. For more information, please consult https://developer.apple.com/support/code-signing. Investigation Apple Developer Forums This issue seems to be known: https://developer.apple.com/forums/thread/746210 Debugging by ourselves We setup an example Xcode project from a default iOS Xcode app template to rule out any project issues. This example project failed with the same error as stated above. In the next step we tried the same example project with a different Apple Developer Account and it successfully distributed the example App through Xcode Cloud. Conclusion It seems like there is no setup issue on developer-side, because our example project works out-of-the-box on a different Apple Developer Account. Our only hope is that Apple will have a look on our Developer Account. Maybe there is some internal setting.

Hello, I'm experiencing an irregular issue with Apple Pay merchant domain verification. As you know, Apple requires domain verification every two months to maintain Apple Pay functionality. The problem is that while the verification sometimes happens automatically without any issues, other times it fails to complete, even though the required file "apple-developer-merchantid-domain-association.txt" is correctly available on our server. When automatic verification fails, the Apple Pay service becomes non-functional on our website, forcing us to perform a manual verification to restore the pending service. Is it normal to encounter such inconsistent automatic verification processes? What could be causing these intermittent verification failures, whereas manual verification always succeed? suggesting this might not be related to IP address restrictions described on the Apple documentation. Thank you in advance,

Hi all, I'm using Apple Sample Code below to create application using dockkit. "Controlling a DockKit accessory using your camera app" https://developer.apple.com/documentation/dockkit/controlling-a-dockkit-accessory-using-your-camera-app?changes=_8 I used vision hand recognition and put the observation data to dockAccessory.track, but Belkin or Insta360 devices never move on iPhone 16 Pro Max with iOS 18.3. If I use other functions like face search (system tracking) in the app, those work ok. I used Belkin and Insta360 Flow 2 Pro to reproduce the problem. My friend is also saying that the custom tracking feature was working fine on the OS 18 beta, but on recent iOS 18.3 that feature does not work. If I can get the iOS 18.0 beta then we can test that feature. But I cannot revert my iOS from 18.3 to the iOS 18.0 Beta. Regards, TO

Hi, I'm testing DockKit with a very simple setup: I use VNDetectFaceRectanglesRequest to detect a face and then call dockAccessory.track(...) using the detected bounding box. The stand is correctly docked (state == .docked) and dockAccessory is valid. I'm calling .track(...) with a single observation and valid CameraInformation (including size, device, orientation, etc.). No errors are thrown. To monitor this, I added a logging utility – track(...) is being called 10–30 times per second, as recommended in the documentation. However: the stand does not move at all. There is no visible reaction to the tracking calls. Is there anything I'm missing or doing wrong? Is VNDetectFaceRectanglesRequest supported for DockKit tracking, or are there hidden requirements? Would really appreciate any help or pointers – thanks!
