I am getting this warning when compiling: Failed to generate flattened icon stack for icon named ... Is it safe to ignore it? Is there a way to fix it? Thank you.

I am writing to bring to your attention a critical issue we are encountering while implementing Apple V2 webhook notifications on our platform. We are currently unable to authorize the token due to signature verification issues. We are unclear about the expected signature and how to validate it correctly. Additionally, we observed that the kid (Key ID), which was available in the header in Apple Pay V1 and used to retrieve the public key, is no longer present in the V2 webhook headers. We have already reviewed the official documentation here: Apple Server Notifications V2, but it does not clarify how to handle the signature validation or proceed. We would appreciate any guidance or documentation that could help us complete this integration successfully. Thank you for your support

I'm adapting my app on iOS 26, and I just found out withAnimation fuction's completion not called in some cases. The same code on iOS 18 was fine. The problem is very fatal, When you check the api, it saids "The completion callback will always be fired exactly one time"，but this time it doens't work. I'm using the Xcode Version 26.0 (17A321) RC1，still not test on a real devcie yet.

I have recently restarted an old code base. The app uses App Groups to communicate with network and endpoint system extensions. For some reason, in Xcode > Target > Signing & Capabilities the app groups are showing up with red text. I feel the red signifies a problem, but I cannot figure out what it is. The app compiles and runs, but I feel there is problem that I am missing. Any idea why App Group names would be displayed in red?

I've created a new project in Xcode. I'm running the Xcode 16.4 and MacOS 15.5. I'm trying to run my barebones project on my iPhone 16 (I'm just getting started). I turned on developer mode on my iPhone and went through the whole process. But in the Signing & Capabilities of my project under status I see two errors... There is a problem with the request entity A device with number 'XXXX8801C' already exists on this team. Provisioning profile "iOS Team Provisioning Profile: [MyBundleID]" doesn't include the currently selected device "My iPhone" (identifier XXXX8801C). I noticed in the devices on the developer portal that my device is showing as "Processing." I feel ike it's stuck. But I can't figure out how to clear it all out and try again. It's been 24 hours since this error came up. I've tried to clear trusted computers on the iPhone. I've deleted the "Derived Data" folder. I've removed my developer account from Xcode and added it again. I've restarted both my Mac and my iPhone multiple times. I've noticed it asked to authorize my computer twice. When I clear the authorized computers and then plug the phone back in it asks twice again. So I'm not sure if this is the issue? No idea why it asks twice but I'm only ever able to respond to the second request as the first request gets blocked in the UI by the second requests if that makes sense? I'm also not able to turn off developer mode on my iPhone. The switch isn't there as the docs state it should be. So again, I feel like this is the phone and the developer portal stuck causing the problem. Note: I saw someone else had encountered this problem and I replied to it and boosted it. But it looks like it was posted in 2017? Hence this new post.

Hi, I have an installer package that runs a postinstall script. The script can take a long time to complete, as one thing it does is copy about 10-30 GB of files using the rsync tool. We noticed on macOS 15 that the installer would fail almost exactly 10 minutes after it started. Looking in the /var/log/install.log, I see a message like this: 2025-07-01 12:54:32-07 Work-M1 package_script_service[21562]: PackageKit: Terminating PKInstallTask(pid:21573). Task has exceeded its 600 seconds of runtime. This does not happen in my testing on macOS 12 (Monterey) I have a few questions about this: A) Is this documented, and which OS introduced this? B) Is there a way a developer can extend or disable the time limit via a setting in the installer package. Or if not, is there a way end end user can disable it temporarily on their system? Thanks, Andrew

Hi, I'm experiencing a super weird and unexpected issue using Icon Composer (Version 1.0 (40)) and Xcode 26 beta 7. I have an icon that includes some minimal text in the icon, as part of the branding of the app. The text is an SVG layer in Icon Composer. Icon Composer has no idea this is text, just a regular SVG layer. When I import the resulting .icon file into Xcode, it appears correct in the Xcode preview. However, when building the app and installing it on the iOS 26 simulator, the font of the text in the icon changes (to the system default font?). It is also cropped, cut off, and off-center. I replicated this with a simple standalone icon and clean project. Is anyone else seeing this?

Hello Developers, I am currently developing a Flutter application where I am implementing both push notifications (for messages) and VoIP call notifications. The implementation works perfectly fine on Android. However, I am facing issues specifically on iOS in the following scenarios: Terminated State: When the app is terminated on iOS, neither call notifications nor message notifications are received. In the background state, things partially work, but in the terminated state, nothing comes through. Debug vs Production: In Debug mode, everything works as expected (both message and call notifications). Once I release the app to TestFlight (Production), the notifications completely stop working: Message notifications are not delivered at all. Call notifications also fail to appear in terminated state. Configuration Details: I have already configured APNs with .p8 key in Firebase. The required capabilities (Push Notifications, Background Modes → Remote notifications, VoIP, etc.) are enabled in Xcode. I also updated the AppDelegate.swift / Notification handling code for production environment. Despite these steps, the same issue persists in production/TestFlight. It seems like the issue is specifically related to production environment handling on iOS, since everything works in debug. My Question: What could be causing push notifications and call notifications to not work in the terminated state on iOS, especially in production/TestFlight builds? Are there additional configuration steps required for APNs, VoIP, or background handling in production that differ from debug mode? Any guidance or similar experiences would be really helpful. Thanks in advance for your support.

We have a simple workflow that just runs the Test action on my unit_tests scheme (see Xcode Cloud workflow configuration screenshot). The workflow is configured to use Xcode 16.4 (Latest Release), macOS Sequoia 15.6 (Latest Release), and iOS 18.0 simulators. Today, this workflow has been consistently running indefinitely. The Xcode cloud runner tries to launch the simulator to execute the tests, but it fails. See the error message in the screenshot from Xcode Cloud logs. Link to corresponding build is in my Feedback Assistant ticket. It continues to retry this operation for a very long time — I had one job that ran for over 90 minutes. Link to corresponding build also in that same Feedback Assistant ticket. Are Xcode Cloud runners perhaps currently undergoing maintenance? Or is something else going on. I would appreciate if Xcode Cloud usage from today could be refunded to my team’s account. Feedback Assistant ticket #FB20195292. Error message: MyApp encountered an error (Failed to prepare device 'iPhone 16' for impending launch. (Underlying Error: Unable to boot the Simulator. launchd failed to respond. (Underlying Error: Failed to start launchd_sim: could not bind to session, launchd_sim may have crashed or quit responding)))

I currently do not want to upgrade to macOS 26, but I still want to install the latest Xcode. Is it required to install macOS 26 if I were to get Xcode 26?

Does anyone have problems with the Pull Request functionality in Xcode 26 RC? I can’t create a new pull request inside Xcode (it always redirects me to the web page). I can’t see changes within an existing pull request (I only see the PR name; I can’t even approve it or request changes). I’ve had this problem since beta 1 of Xcode 26. Does anyone know how to fix this?

I can log in but not renew dev programm payment: Sorry, you can’t enroll at this time. Your Apple Account is already associated with the Account Holder of a membership. In trader contact i see a wrong DUNS Number but i enabled no chance to edit. When i try to get a support call, error message wrong email. But in account is the right one confirmed. Thanks for helping, how can i enroll to the dev programm and publish my new App? Android is now approved and i stuck with IOS here.

Under Xcode 26 beta 3 I'm trying to build a project which uses Metal. I've installed the Metal Toolchain 26.0 under Settings -> Components, but when I start a build it fails during the "Prepare build" step with the following error (repeated many times): stat(/var/run/com.apple.security.cryptexd/mnt/com.apple.MobileAsset.MetalToolchain-v17.1.5276.7.Pb9SLL/Metal.xctoolchain/usr/bin/clang): No such file or directory (2) I've confirmed that there is in fact no 'clang' binary in that directory. I've tried using xcode-select to set the Xcode 26 Beta app as the active developer directory, and xcodebuild -version shows: Xcode 26.0 Build version 17A5276g Any ideas on other things to try?

I have now signed out of my account in Xcode, quit the application, signed back in, and also cleared the Xcode derived data and cache.

A new version of the Configuring your app to use alternate app icons sample code is available for download. The sample uses Icon Composer files and supports iOS 18 or later.

I am trying to validate my update for my app to be ready for iOS 26 with the new Icon Composer .icon file. Everywhere I read says that the old AppIcon in the assets folder wouldnt be used and to just drop the .icon file in the project navigator and link it properly. I do that and its still asking for a .png file; I add the 1024x1024 .png file and its still not working. I am very lost and dont know where to go from here I have both the .icon and .png app icons in there. My app deployment target is at iOS 26, Xcode Project format 16.3 (I dont see 26 so assuming 16.3 is the highest). I feel I have done all the things, and advice? Thanks in advance!

I am having similar problems to this guy on Stack Overflow over a year ago: https://stackoverflow.com/questions/77627852/functions-of-iouserscsiperipheraldevicetype00-class-in-scsiperipheralsdriverkit There are also a few questions on this forum about this object, none of which have answers. I can get my driver to match and instantiate, but nobody calls my UserDetermineDeviceCharacteristics (which does nothing, just returns kIOReturnSuccess) I can attempt to call UserSuspendServices(), UserResumeServices() or UserReportMediumBlockSize() and all of them return kIOReturnUnsupported. It doesn't matter if I've unmounted the disk or not. Is the custom driver supposed to be instantiated beside the kernel's IOSCSIPeripheralDeviceType00, or should it replace it? What should its IOProviderClass be? What should its IOClass be - IOUserService, or something else? see FB19678139 and FB19677920

My code was running with with the version before Xcode 26 RC. I recompiled one last time. Now I'm getting the error: A server with the specified hostname could not be found let now = Calendar.current.date(byAdding: .hour, value: 1, to: Date())! let nextWeek = Calendar.current.date(byAdding: .day, value: 14, to: Date())! do { let (dailyForecast, hourlyForecast, currentWeather, alertWeather) = try await weatherService.weather(for: thisLocation, including: .daily, .hourly(startDate: now, endDate: nextWeek), .current, .alerts) Suggestions?

Xcode 26 RC is not available on Xcode Cloud. This is a serious blocker affecting developers trying to be on App Store on day 1 of the OS 26 release. Is there an estimate when this can be in place?
