Overview

I'm seeing a lot of unexpected CPU usage when running the iOS 26.1 simulator. Looks like a "MercuryPosterExtension" is crashing over and over, which then causes the "ReportCrash" process to run, presumably to create the crash report. Doesn't happen on device, nor on iOS 26.0 simulator. I suspect MercuryPoster is related to wallpaper. I also don't see any wallpaper background in my simulator.

Hi, I can't get into "manage" sandbox account. I either get to a screen to put my password in. Here there is no way to click "next" or "login". (I have tried pressing "enter" on my keyboard to no effect). Or I get directly into "Cannot Connect" page. I have tried this two days in a row. I have tried turning it off and on again. I have tried logging out and in. Device: iPhone 13 pro max, iOS: 16.0.3 (also tried the version before this)

Hi all,  Apple dropping on-going development for FireWire devices that were supported with the Core Audio driver standard is a catastrophe for a lot of struggling musicians who need to both keep up to date on security updates that come with new OS releases, and continue to utilise their hard earned investments in very expensive and still pristine audio devices that have been reduced to e-waste by Apple's seemingly tone-deaf ignorance in the cries for on-going support.  I have one of said audio devices, and I'd like to keep using it while keeping my 2019 Intel Mac Book Pro up to date with the latest security updates and OS features.  Probably not the first time you gurus have had someone make the logical leap leading to a request for something like this, but I was wondering if it might be somehow possible of shoe-horning the code used in previous versions of Mac OS that allowed the Mac to speak with the audio features of such devices to run inside the Ventura version of the OS.  Would it possible? Would it involve a lot of work? I don't think I'd be the only person willing to pay for a third party application or utility that restored this functionality. There has to be 100's of thousands of people who would be happy to spare some cash to stop their multi-thousand dollar investment in gear to be so thoughtlessly resigned to the scrap heap.  Any comments or layman-friendly explanations as to why this couldn’t happen would be gratefully received!  Thanks,  em

Since upgrading to Xcode 26 beta 4 and using the iOS 26 simulator for testing our app, we've stopped being able to receive device tokens for the simulator from the development APNS environment. The APNS environment is able to return meta device information (e.g. model, type, manufacturer) but there are no device tokens present. When running the same app using the iOS 18.5 simulator, we are able to register the device with the same APNS environment and receive a valid device token.

Using Xcode to build and deploy the app to my watch, this is what I get: “Waiting to reconnect to Apple Watch. Previous preparation error: Transport error." And then “Connecting to Apple Watch. Xcode will continue when the operation completes.” And these messages continue to switch between each other. Sometimes the watch to connect and the application starts, but more often a scenario occurs with endless reconnection. I'm using: MacOS 14.4.1 (MacBook Pro 2019; 1.4 GHz Quad-Core Intel Core i5), Xcode 15.3, Watch OS 10.2 (Apple Watch SE 1), iOS 17.1.1 (iPhone 15 Pro). Methods I tried: Connecting Macbook, iPhone and Watch to the same WIfi network; Disabling Watch (and IPhone) from the "Devices and Simulators" menu and setting up Watch (and IPhone) from the beginning. Any help?

Hi all, Has anyone else run into this issue in Xcode 26? I’m logged into my paid ChatGPT Plus account, but the Xcode integration doesn’t seem to recognize the subscription. After a short period of use, I get the following error: “Over daily limit. ChatGPT in Xcode will be unavailable for up to 24 hours. For higher limits, sign in with a paid ChatGPT account.” Since I’m already signed in with a paid account, this looks like either a bug or a limitation specific to Xcode. Is this expected behavior, or has anyone found a workaround to make Xcode properly recognize Plus accounts? Thanks in advance for any guidance.

I have an app (currently not released on App Store) which runs on both iOS and macOS. The app has widgets for both iOS and macOS which uses user preference (set in app) into account while showing data. Before upgrading to macOS 15 (until Sonoma) widgets were working fine and app was launching correctly, but after upgrading to macOS 15 Sequoia, every time I launch the app it give popup saying '“Kontest” would like to access data from other apps. Keeping app data separate makes it easier to manage your privacy and security.' and also widgets do not get user preferences and throw the same type of error on Console application when using logging. My App group for both iOS and macOS is 'group.com.xxxxxx.yyyyy'. I am calling it as 'UserDefaults(suiteName: Constants.userDefaultsGroupID)!.bool(forKey: "shouldFetchAllEventsFromCalendar")'. Can anyone tell, what am I doing wrong here?

Im having trouble enabling Live Activities in a new app. The option is not available in Xcode or in the developer portal. Is there something I have to do to activate this option?

I'm trying to setup a macOS 26 build environment in a VM (using UTM and the virtualization framework Apple provides). I have Xcode 26 installed and have logged into my Apple ID and verified that the team and other configuration looks fine in Xcode settings. When trying to build the macOS app, I see errors saying the VM's device ID has not been registered. I have confirmed that the device ID is registered both in the Provisioning portal AND the downloaded .provisionprofiles (in Library > Developer > Xcode > UserData). This problem appears on multiple targets (e.g. the main app and extensions). If I try to manually provision the app, using the Provisioning portal, I can build the product, but it will not launch because of Gatekeeper issues. Finally, signing to run locally doesn't work either. As the app launches, frameworks refuse to load because Team IDs don't match. With ad hoc provisioning, there are no Team IDs. I've come to the conclusion that this just isn't possible. Which is a shame because I need to support products with a build environment on macOS 15 and cannot move over to macOS 26 yet. I suspect many developers outside of Apple are in a similar position.

We use SwiftUI's .tabViewBottomAccessory in our iOS apps for displaying an Audio MiniPlayer View (like in the Apple Music App). TabView(selection: $viewModel.selectedTab) { // Tabs here } .tabViewBottomAccessory { if viewModel.showAudioMiniPlayer { MiniPlayerView() } } The Problem This code works perfectly on iOS 26.0. When viewModel.showAudioMiniPlayer is false, the accessory is completely hidden. However, on iOS 26.1 (23B5059e), when 'viewModel.showAudioMiniPlayer' becomes false, the MiniPlayerView disappears, but an empty container remains, leaving a blank space above the tab bar. Is this a known Bug in iOS 26.1 and are there any effective workarounds?

When I create new build for TestFlight, it could not install from Test Flight, and show any error/warning/tip, from device's console, I got this error: -[IXSDataPromise cancelForReason:client:error:]: <IXSPlaceholder(0xc1acd7480) Name:App Placeholder: XXXXXXX(com.YYYYYY) Creator:App Store UUID:8AB2A59C-C367-42E1-990A-ACAFD8F9F4B9 Location:[system-defined]> : canceled by client 17 for reason Error Domain=IXUserPresentableErrorDomain Code=1 "This app could not be installed at this time."

I count not find anything about [IconPlatform] in my code, and could not find it in the info.plist files in the .ipa file. I only do some tiny code change for my app, and it could install in yesterday, but could not install for today. So how to resolve this issue? I need submit my new build for a urgent company events.

My app start up has became horrid. It takes 1 minute to open SQLlite database for my rust core. Impossible to work... I have Address Sanitizer, Thread Perf Checker and Thread Sanitizer disabled...

Thank you again for pushing the web forward in VisionOS 2, super exciting! The latest WWDC24 video touched on VR experiences for VisionOS2.0 using WebXR, however there was no mention of passthrough AR experiences. Samples such as this one are not supported: https://immersive-web.github.io/webxr-samples/immersive-ar-session.html In Settings > Safari, there is a feature flag for the AR WebXR module, but enabling it did not seem to change anything. Is this the expected behavior at this time? Any developer preview(s) we could try?

I added my first subscription to my app using StoreKit's SubscriptionStoreView. Everything worked as expected in the debug environment and also in TestFlight. So I submitted my app and subscriptions to App Store Connect, got everything Approved and released. After updating my app through App Store and checking the Subscription View, it just says "Subscription Unavailable. The subscription is unavailable in the current storefront." I waited around 3 days and still getting the same message. Now the very strange behavior starts. I went to App Store Connect, I made and edit to the subscription description, saved, removed the edit, saved, and submitted to review. 15 minutes later the subscriptions appear in my app and everything works as expected. After getting the edit approved, the Subscription View in my app again only showed the message "Subscription Unavailable. The subscription is unavailable in the current storefront." No user is able to see the subscriptions anymore, even though it worked as expected before the edit was approved. So I did the same as before. Again, make an edit to the subscription description, save, remove the edit, save, submit to review. 15 minutes later the subscriptions are again available in my app and it works as expected. This is definitely not the expected behavior and submitting the subscription edits every day is wasting the App Review Team's time as well as mine. I contacted Apple Developer Support but I didn't get any reply back (at least yet). I am not the only one experiencing this. I found a friend online who has the exact same issue, and is able to temporarily solve it by making an edit to the subscription description as well. So far it has been a huge headache, and we are losing customers this way. Please if anyone has experience with this problem, or has any suggestions, they will be greatly appreciated. Thank you so much, Tomas

I use Apple Business Manager to install apps on my office iPads and to track them. I am a beta tester for a company that pushes new versions of their software through TestFlight. These iPads are logged into managed apple accounts [apple IDs] under my Apple Business Manager account. When I attempt to open TestFlight, I receive a message "TestFlight is currently unavailable, try again later." If I logout and sign in an iPad under a consumer Apple Account, TestFlight works properly. I however, want to use these iPads under my apple business account.

Aloha. Opening and closing VPN tunnels results in as many utun interfaces as the amount of times the tunnel has been opened. These interfaces stay present and seem to be removed only upon system reboot. We are using the NetworkExtension as a SystemExtension on macOS to create the virtual interfaces. Is this the normal behaviour. Has anybody else experienced this? utun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1380 inet6 fe80::8038:c353:17cd:c422%utun0 prefixlen 64 scopeid 0xf nd6 options=201<PERFORMNUD,DAD> utun1: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 2000 inet6 fe80::cfb6:1324:d7e9:5d5%utun1 prefixlen 64 scopeid 0x10 nd6 options=201<PERFORMNUD,DAD> utun2: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1300 options=6463<RXCSUM,TXCSUM,TSO4,TSO6,CHANNEL_IO,PARTIAL_CSUM,ZEROINVERT_CSUM> utun3: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1300 options=6463<RXCSUM,TXCSUM,TSO4,TSO6,CHANNEL_IO,PARTIAL_CSUM,ZEROINVERT_CSUM> utun4: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1300 options=6463<RXCSUM,TXCSUM,TSO4,TSO6,CHANNEL_IO,PARTIAL_CSUM,ZEROINVERT_CSUM> utun5: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1300 options=6463<RXCSUM,TXCSUM,TSO4,TSO6,CHANNEL_IO,PARTIAL_CSUM,ZEROINVERT_CSUM> utun6: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1300 options=6463<RXCSUM,TXCSUM,TSO4,TSO6,CHANNEL_IO,PARTIAL_CSUM,ZEROINVERT_CSUM> utun7: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1300 options=6463<RXCSUM,TXCSUM,TSO4,TSO6,CHANNEL_IO,PARTIAL_CSUM,ZEROINVERT_CSUM> utun8: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1300 options=6463<RXCSUM,TXCSUM,TSO4,TSO6,CHANNEL_IO,PARTIAL_CSUM,ZEROINVERT_CSUM>

When I use the .zoom transition in a navigation stack, I get a glitch when interrupting the animation by swiping back before it completes. When doing this, the source view disappears. I can still tap it to trigger the navigation again, but its not visible on screen. This seems to be a regression in iOS 26, as it works as expected when testing on iOS 18. Has someone else seen this issue and found a workaround? Is it possible to disable interrupting the transition?

I am working on an app for a home automation device. If I were using HomeKit exclusively I could add custom services or custom characteristics on standard services and these things would all be reported to my app via HomeKit. There is sample code from Apple that demonstrates how to do this. When a Matter device is commissioned using HomeKit you might expect custom clusters and/or custom attributes in a standard cluster would be translated to appropriate HomeKit services and characteristics, but this doesn't appear to be the case. Is there a way to have HomeKit do this? If not it seems I would need to use Matter directly rather than via HomeKit to access custom features. But if I commission the device using Matter in my app then I understand a new fabric is created and the device would not show in the Home app. Maybe the user needs to commission the device twice, once with my custom app and once with the Home app? That seems like a poor user experience to me. Perhaps that is the price paid for using a cross-platform standard? Is there a better way to get the same level of customization using Matter that I am able to get using HomeKit?

Hi, After updating to iOS 26, our app is facing playback failures with AVPlayer. The same code and streams work fine on iOS 18 and earlier. Error - Domain[CoreMediaErrorDomain]:Code[-15628]:Desc[The operation couldn’t be completed.]:Underlying Error Domain[(null)]:Code[0]:Desc[(null)] Environment: iOS version: ios 26 React Native: 0.69 Video library: react-native-video (AVPlayer under the hood) Stream type: HLS (m3u8) with segment (.ts) files Observed behaviour: Playback works initially on iOS 26. On iOS 26, the stream fails at runtime after a few seconds/minutes (not on first load). Network logs show 307 redirects on some segment requests. After this, AVPlayer throws the above error. Playback fails intermittently on slow/unstable networks.
