Hello, I upgraded my computer system to Mac OS 26.1 and also upgraded Xcode to version 26.1.1. I have tried various methods but the problem is still not solved, which is very frustrating. Please provide a specific and detailed solution. Thank you very much!

Alarms set with AlarmKit on iOS 26.1 stop ringing after upgrading to iOS 26.2 beta 3 or later
We first discovered this issue in our own product, but we were able to reproduce it even when using Apple’s official demo: https://developer.apple.com/documentation/alarmkit/scheduling-an-alarm-with-alarmkit Reproduction Steps: Set an alarm on iOS 26.1 using AlarmKit. Upgrade the device to iOS 26.2 beta 3 or later. The alarm will no longer ring. Based on our testing, versions prior to 26.2 beta 2 do not exhibit this issue, so it appears that something introduced in beta 3 has caused the regression. The results are as follows: iOS 26.1 → iOS 26.2 beta 2 or earlier: Alarms ring normally iOS 26.1 / iOS 26.2 beta 2 → iOS 26.2 beta 3 / iOS 26.2 RC: Alarms fail to ring iOS 26.2 beta 3 → iOS 26.2 RC: Alarms ring normally This issue is critical. Users currently on iOS 26.1 may experience alarms failing to ring after updating their system, which can cause real-life disruptions (e.g., being late for work). We strongly recommend addressing this as soon as possible. Xcode Version: Version 26.1.1 (17B100) Feedbac

Reply to ✖ Failed to register bundle identifier
Thanks for your post, an HTTP error seems more like a network or firewall issue. Have you tried using the computer connected to another network? The error “Failed to register bundle identifier” accompanied by messages such as “Access forbidden” or “You currently do not have access to this membership resource,” it is likely that there is an issue with your Apple Developer account or the permissions associated with it. However, in your post, you mentioned that you are an administrator for the account. Could you please log in to the account and verify that you are using the correct account? Verify Your Apple Developer Account: Ensure that your Apple Developer account is active. If you can login into the browser you are good. Check Your Membership Role: You said you are an admin. Make sure that your account has the appropriate role to register bundle identifiers. Typically, roles like Admin or App Developer are required. You can verify this under People in your Apple Developer account settings as you said you are

Stale TBD Files Cause Runtime Crash When Framework Changes from Dynamic to Static
Stale TBD Files Cause Runtime Crash When Framework Changes from Dynamic to Static Summary When using EAGER_LINKING=YES, Xcode generates TBD files for dynamic frameworks. When a framework changes from dynamic to static, Xcode doesn't remove the stale TBD, causing dyld: Library not loaded crash at runtime. Environment Xcode 16.4 (16F6), macOS Darwin 24.6.0, iOS Simulator 18.5 Steps to Reproduce Project Structure: MainApp (EAGER_LINKING=YES) ProjectA/SharedLib (dynamic, mh_dylib) ProjectB/SharedLib (static, staticlib) Steps: Build with ProjectA (dynamic framework) → TBD created in EagerLinkingTBDs Switch workspace to ProjectB (static framework) without cleaning DerivedData Build again → BUILD SUCCEEDED Run app → CRASH: dyld: Library not loaded Root Cause Xcode adds -F EagerLinkingTBDs before -F Build/Products: -F/.../EagerLinkingTBDs/Debug-iphonesimulator ← checked FIRST -F/.../Build/Products/Debug-iphonesimulator ← checked SECOND The linker finds the stale TBD first and treat

Reply to "Signing certificate" and post-installation assignment fail due to IOPCIPrimaryMatch
My current goal is to ship the PCIe DriverKit. I want my customers to be able to install our DriverKit without having to disable SIP or anything like that. Absolutely. Why is there a difference between the Apple Development value and the Developer ID value? The two different values happen because of the development only variant that's added to all accounts. (a) This is the development only configuration (which all accounts have): 0xFFFFFFFF&0x00000000 (b) And this is the specific configuration you were approved for, which is unique to your account: 0x00001916&0x0000FFFF Unfortunately, the portal and Xcode handling of these overlapping configurations doesn't work all that well. You can find a description of what's actually going on here. However, note that I don't think the flow described at the end of that post actually works today. However, according to the URL you provided, would manual signing using a provisioning file created with a Distribution Developer ID be better? First off, please f

Locking App Orientation to Landscape in Playground
Hello! I’m building my Swift Student Challenge project in Swift Playgrounds, and I’ve run into an issue with app orientation. Since this is a game, the layout and interactions only work correctly in landscape, but Playgrounds doesn’t offer the usual orientation settings you’d configure in Xcode. Is there a recommended way to force a landscape-only experience in Swift Playgrounds using SwiftUI? Any workarounds or guidance would be greatly appreciated! Thank you!

Your case ID for this conversation is 102769512657.
Hi everyone, I’m unable to enable Xcode Cloud for any app on my account. At the final step of the Xcode workflow setup (“Confirm App on App Store Connect”), pressing Complete always returns: “ could not be added to Xcode Cloud. Authentication credentials are invalid.” This affects both existing apps and completely new test apps with fresh bundle IDs. What I’ve verified • I am Account Holder and Admin. • All agreements are accepted. • App creation, bundle ID registration, and certificate management work normally. • I’ve removed/re-added my Apple ID in Xcode and cleared all Xcode-* tokens from Keychain. • Test apps in clean Git repos reproduce the same error. Support I have already opened Case ID 102769512657 with Apple Developer Support, but I’m posting here in case others have seen this issue or know of additional steps to confirm the provisioning state.

NSButtons disappear on macOS 26
I have attached 2 images of our Mac Apps user interface. The app is built for macOS 15.6 or newer. On macOS 15 and earlier everything looks fine. But the same App running on macOS 26 the controls disappear. We were able to temporarily resolve the problem by adding UIDesignRequiresCompatibility to the info.plist. This type of nonsense happens all over the app without the compatibility switch. Shouldn't all these legacy controls be backward compatible on Glass? This part of the app where the controls are disappearing is built in Swift (not swift ui) and uses standard programatic layout and visual constraints. On macOS 26, there are no Xcode warnings or layout errors on the console relative to the layout so we are confused as to how we would resolve this without the use of UIDesignRequiresCompatibility. Is this some kind of bug in NSControl glass compatibility? We are not likely to move the entire app into SwiftUI anytime soon. How would we resolve this?

Reply to URLRequest(url:cachePolicy:timeoutInterval:) started to crash in iOS 26
Phew, I already feel bad asking you again 😅 It turns out that MTE and Malloc Stack Logging cannot be enabled at the same time. But I've tried to enabled Malloc Stack Logging, and then get delayed crash somewhere else. Unfortunately, I didn't really understand where/what to look for in Xcode. I tried to hit the 'Memory Graph Debug' but then the crash context seemed to get lost... most likely I am doing it wrong... A little context of our app: An UIPageViewController where you can swipe left/right to see the next/previous image. An UIViewController that has a TileImageView subview TileImageView that shows an image. This view is using CATileLayer. When draw(rect:) is called for a specific tile, we either show a cached tile or send a network request to a local server for the tile data. When the network response is received (callback in draw(rect:) we call the view's draw(rect:) to update with tile. Now if I scroll through the pages the crash may occur. As stated before this code was working fine before

Reply to GitLab Self-Managed installation was incomplete.
One thing is that even though Xcode SCM is configured with HTTPS and the repo has only HTTPS remote configured when setting up Xcode the the authorisation flow flashes this redirect URL: client_redirect_path=/ci/api/teams/REDACTED/internal-setup-flow/scm-providers&team_id=REDACTED&scm_provider_id=REDACTED&client_redirect_base_uri=https://appstoreconnect.apple.com?***git_clone_url=ssh://git[@]gitlab._REDACTED_/_REDACTED_.git***&provider=gitlab-hosted&redirectAfterSuccessUri=https://appstoreconnect.apple.com/teams/_REDACTED_/ci-setup/success&code=_REDACTED_&state=_REDACTED_ Why is Xcode Cloud attempting to clone via SSH? git_clone_url=ssh://git[@]gitlab.REDACTED/REDACTED.git

Enabling xcode project for CI/CD
Hello All, I am new to apple ecosystem. We have a xcode project whose code is scattered across different repos. We are trying setup CI/CD for this Xcode project to get build so that we could know build issue. Clone/Update all repos – which I can do via some script Generate xcode projects from sources synced in step 1. This is where we want your help. How should we approach this? What apple suggest for this ? In this step we don't want to use any third part tool (like CMake) to generate Xcode projects. Build targets to know build errors – This we can easily do via xcodebuild command line tool. Please share you input/thought on this. Your input is highly appreciated.

[quote='868298022, bims, /thread/806594?answerId=868298022#868298022, /profile/bims'] Looking at the ips-file I found that it does not show the finding that Xcode show [/quote] Right. Xcode has MTE smarts beyond what the human readable crash report shows. To see the underlying data, open the JSON crash report and search for memoryErrorReport. With some reformatting you get this: memoryErrorReport : { faultAddress:0x0c00000d9de112c0, blamedAllocation: { size:48, allocationTrace:…, deallocationTrace:…, isFreed:true, address:0x0c00000d9de112c0 }, errorType:use-after-free }, The allocationTrace and deallocationTrace backtraces need further massaging. I did a hack-ish job of that and have included the results at the end of this post. I wanted the JSON crash report so that I could run it through some internal tools. I was able to do the first part of that today. I was hoping it might point me at some known bugs. It did, but those were resolved a while bug and thus are unlikely to be the cause of t

Reply to Xcode and Reading documents from a URL connection.
[quote='868358022, Apple_Fox, /thread/807599?answerId=868358022#868358022, /profile/Apple_Fox'] Is that something that would cause errors for downloading the documents … ? [/quote] It very much depends on the server. Given a URL for something downloadable, some servers allow you to download the resource directly and other require you to jump through hoops. You can see this even on Apple servers. For example, SF Symbols 7 is directly downloadable: https://devimages-cdn.apple.com/design/resources/download/SF-Symbols-7.dmg but Xcode 26.1.1 is not: https://download.developer.apple.com/Developer_Tools/Xcode_26.1.1/Xcode_26.1.1_Universal.xip In the Xcode case, the server redirect the download request to a login page. That login page assumes that the client is a person using a web browser, and it’s very hard to programmatically deal with the required authentication.

App Store Connect release notes RSS feed
I want to keep an eye on the App Store Connect release notes to find out when builds created with Xcode 26.2 RC will be accepted. I tried to add https://developer.apple.com/help/app-store-connect/release-notes/ to my RSS reeder but the items listed are not the same, it’s the items from the latest news from Apple Developer instead. Can we get an RSS feed please? Seems will be useful to monitor these release notes over time.
