Overview

I have been working on a multi-platform multi-touch HID-standard digitizer clickpad device. The device uses Bluetooth Low Energy (BLE) as its connectivity transport and advertises HID over GATT. To date, I have the device working successfully on Windows 11 as a multi-touch, gesture-capable click pad with no custom driver or app on Windows. However, I have been having difficulty getting macOS to recognize and react to it as a HID-standard multi-touch click pad digitizer with either the standard Apple HID driver (AppleUserHIDEventDriver) or with a custom-coded driver extension (DEXT) modeled, based on the DTS stylus example and looking at the IOHIDFamily open source driver(s). The trackpad works with full-gesture support on Windows 11 and the descriptors seem to be compliant with the R23 Accessory Guidelines document, §15. With the standard, matching Apple AppleUserHIDEventDriver HID driver, when enumerating using stock-standard HID mouse descriptors, the device works fine on macOS 14.7 "Sonoma" as a relative pointer device with scroll wheel capability (two finger swipe generates a HID scroll report) and a single button. With the standard, matching Apple AppleUserHIDEventDriver HID driver, when enumerating using stock-standard HID digitizer click/touch pad descriptors (those same descriptors used successfully on Windows 11), the device does nothing. No button, no cursor, no gestures, nothing. Looking at ioreg -filtb, all of the key/value pairs for the driver match look correct. Because, even with the Apple open source IOHIDFamily drivers noted above, we could get little visibility into what might be going wrong, I wrote a custom DriverKit/HIDDriverKit driver extension (DEXT) (as noted above, based on the DTS HID stylus example and the open source IOHIDEventDriver. With that custom driver, I can get a single button click from the click pad to work by dispatching button events to dispatchRelativePointerEvent; however, when parsing, processing, and dispatching HID digitizer touch finger (that is, transducer) events via IOUserHIDEventService::dispatchDigitizerTouchEvent, nothing happens. If I log with: % sudo log stream --info --debug --predicate '(subsystem == "com.apple.iohid")' either using the standard AppleUserHIDEventDriver driver or our custom driver, we can see that our input events are tickling the IOHIDNXEventTranslatorSessionFilter HID event filter, so we know HID events are getting from the device into the macOS HID stack. This was further confirmed with the DTS Bluetooth PacketLogger app. Based on these events flowing in and hitting IOHIDNXEventTranslatorSessionFilter, using the standard AppleUserHIDEventDriver driver or our custom driver, clicks or click pad activity will either wake the display or system from sleep and activity will keep the display or system from going to sleep. In short, whether with the stock driver or our custom driver, HID input reports come in over Bluetooth and get processed successfully; however, nothing happens—no pointer movement or gesture recognition. STEPS TO REPRODUCE For the standard AppleUserHIDEventDriver: Pair the device with macOS 14.7 "Sonoma" using the Bluetooth menu. Confirm that it is paired / bonded / connected in the Bluetooth menu. Attempt to click or move one or more fingers on the touchpad surface. Nothing happens. For the our custom driver: Pair the device with macOS 14.7 "Sonoma" using the Bluetooth menu. Confirm that it is paired / bonded / connected in the Bluetooth menu. Attempt to click or move one or more fingers on the touchpad surface. Clicks are correctly registered. With transducer movement, regardless of the number of fingers, nothing happens.

Itself been 4-5 days my Image playground has showing the “Downloading Support for Image Playground “

I want to support Genmoji input in my SwiftUI TextField or TextEditor, but looking around, it seems there's no SwiftUI only way to do it? If none, it's kind of disappointing that they're saying SwiftUI is the path forward, but not updating it with support for new technologies. Going back, does this mean we can only support Genmoji through UITextField and UIViewRepresentable? or there more direct options? Btw, I'm also using SwiftData for storage.

We are seeing an issue where sending data using the asynchronous method HKWorkoutSession.sendToRemoteWorkoutSession(data: Data) will never return in some cases (no success nor failure). This issue is happening for roughly 5% of Workouts started and will stay broken for the whole workout. The other 95% of the workouts, the connection works flawlessly. This happens on both watchOS 10 and 11, and with phones running iOS 17 or 18. The issue is quite random and not reproducible. Our app has thousands of workouts a day that use the workout session workout data send, with constant messages being send every few seconds. In some of those 5% cases the "sendToRemoteWorkoutSession" will throw way later, like 30+ minutes later, if the watch app is awake long enough to capture a log of a failure. Our code uses the same flow as in the sample project: https://developer.apple.com/documentation/healthkit/workouts_and_activity_rings/building_a_multidevice_workout_app Here is some sample code, which is pretty simple. Setup code: let workoutSession = try HKWorkoutSession(healthStore: healthStore, configuration: configuration) workoutSession.delegate = self activeWorkoutSession?.startMirroringToCompanionDevice { success, error in print("Mirroring started on companion device: \(success), error: \(error)") } workoutSession?.prepare() then later we send data using the workout session: do { print("Will send data") try await workoutSession.sendToRemoteWorkoutSession(data: data) print("Successfully sent data") // This nor the error may be called after waiting extensive amounts of time } catch { print("Failed to send data, error: \(error)") // This nor the success may be called after waiting extensive amounts of time } So far, the only fix is to restart the phone and watch at the same time, which is not a great user experience. Is anyone else seeing this issue? or know how to fix this issue?

In Xcode's (version 16.1) "Devices and Simulators" window pressing the device's context menu item "Show Provisioning Profiles..." does nothing: no new window, no message, nothing. How can I fix this?

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?

When my app is in the background, I create a Live Activity through a push notification with token get from pushToStartTokenUpdates, and this process works fine. However, without opening the app, how can I retrieve the new push token for this Live Activity again and use it for subsequent updates to the Live Activity content?

I'm following: https://developer.apple.com/documentation/applemapsserverapi/creating-a-maps-identifier-and-a-private-key#Create-a-Maps-ID to create map id and private key. On step #4 I can't find "Maps IDs checkbox" on the web page, blow is the screen capture which contains all options I have on my page:

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 am getting this issue when trying to accept an invite to a new test version of our app. ****Unable to Accept invite This invitation cannot be accepted because your Apple Account, xxxxxxxx.me.com, has already been associated to this app.**** Can you help please?

On macOS 15.2, any Mac Catalyst project that does not support portrait iPad orientation will no longer be able to successfully show the contents of any popover controls. This does not appear to be a problem on earlier versions of macOS and it only affects Mac Catalyst builds, not "Designed for iPad" builds. STEPS TO REPRODUCE Create a project that utilizes Mac Catalyst. Create a simple button that shows a popover with simple content. Remove Portrait as a supported orientation. Run the project on macOS 15.2 as a Mac Catalyst build. Note that the content inside the popover is not shown the popover is shown. Run the project as Designed for iPad. Note that the popover content shows correctly.

Is it possible to change the title "Choose Activites" and also remove the search on the FamilyActivityPicker?

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.

Hello, I have the following problem. I’m developing a NoCode app using the FlutterFlow platform and have been working on it for over a year. This time, after publishing a new version of the app through FlutterFlow, I tried logging into Apple Store Connect, but I got an error saying that I had made too many login attempts and needed to try again later. However, I hadn’t attempted to log in before that at all. No matter how long I wait—24 hours, 48 hours—the same error keeps appearing, meaning I still can’t access my account. Apple Support hasn’t responded for 4 days, and in total, I’ve been locked out of my account for over 9 days. Please help me understand what might be causing this issue. Apple Store Connect refuses to send me an SMS with the login code.

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.
