realitytool requires Metal for this operation and it is not available in this build environment
Hello, I'm getting started for my project with Xcode Cloud since I upgraded to the macOS Sequioa Beta and Xcode 16 now refuses to archive builds for TestFlight. Somewhere very late in the build process I get the following error: realitytool requires Metal for this operation and it is not available in this build environment The log says this happens at: Compile Skybox urban.skybox My project uses RealityKit. How can I fix this issue? Thanks!

Matter Media Playback Cluster
Hello, I am currently working on personal project based on Matter. I need to create a Basic Video Player as specified in Matter's standard embedding the Media Playback Cluster. I went through the reading of how Apple now supports Matter as a standard : linkText My understanding of the following schematic, is alongside : HomeKit Accessory Protocol (HAP) Framework API Related HAP accessories underneath the homeKit framework. Developpers also find under the Homekit framework : CHIP (Connected Home IP) Framework API Related Matter accessories this time Both types of accessories/devices can be commissioned in the HomeKit ecosystem seemlessly. Each framework has it's documentation : HAP : https://developer.apple.com/documentation/homekit/hmhomemanager CHIP : https://developer.apple.com/documentation/matter I want through the process of installing XCode and the HomeKit Accessory Simulator. In the list of HomeKit Accessories I did not see any Media related devices : The list of currently supported devices is limited as I read here and will be enriched with time : https://support.apple.com/en-us/102135#:~:text=The%20Home%20app%20currently%20supports,%2C%20temperature%2C%20and%20humidity). In the meantime, as I read the matter documentation, I read several references made to the Media Playback : https://developer.apple.com/documentation/matter/mtrclustermediaplayback https://developer.apple.com/documentation/matter/mtrbaseclustermediaplayback https://developer.apple.com/documentation/matter/clusters#Interacting-with-the-Media-Playback-cluster My questions are : Are Matter Basic Video Players, (Media Playback) supported in HomeKit ? Why aren't they listed in HomeKit Accessory Simulator ? How can I add a Basic Video Player in HomeKit and display it's Media Playback controls once I have added the device to HomeKit ? Thank you for your Answer. Regards David

I'm not able to download the p8 Private Key
I'm not able to download my Private key since Yesterday and I get the following error message when I click on "Download" Auth Key can only be downloaded once. This auth key has already been downloaded. I revoked all my existing keys and created new ones and I get the same error message. I tried all the mentioned solutions on this forum and StackOverflow like using Safari,turning off VPNs,removing spaces from Key name, using my iPhone, using a Mac, incognito/private mode on Windows Microsoft Edge, clicking done then pressing download after, right clicking on download Linked File as...nothing seems to work

VPN causes developer cert in keychain to become untrusted
After not happening to me for a few months, this issue has started hitting me again with currently %100 reproducability. If turn on VPN on my Mac then instantly the developer certificates within the keychain become untrusted. But that's not all, if VPN is then turned off the certificates do not revert to their trusted status but remain untrusted. The consequence of this is that if VPN is turned on and then a build is perform, it fails, and the only way to fix things is to delete the cert(s) from they keychain and re-install them. As a remote worker, having this happen several or even dozens of times a day is incredibly annoying and frustrating. This issue has been occurring for literally years, sometimes it occurs very often, others while its quiet for a while, and has spanned multiple versions of Xcode and Mac OS. So whatever the cause is its endemic. It doesn't just affect myself, but all the members in my development team. I'm currently using Xcode 14.1 RC 2 and Monterey but I've seen this issue occur with many versions of Xcode and Mac. (I'm using Cisco AnyConnect Secure Mobility Client). If the VPN is somehow interfering/affecting the connectivity aspect when an attempt is made by Xcode to validate the certificate, then why does it not rectify itself after turning off VPN? This is so so so so annoying. Can somebody please comment on why this happens and if there's a way to prevent it.

Xcode Cloud on Apple Silicon any time soon?
I'm currently using another provider for CI/CD. They've been offering Apple Silicon builds for over a year now. When we switched over, we saw our build times cut in half. I've seen similar results locally, back when I bought an M1 Mac. So, recently, I tried to use Xcode Cloud on my project. My build time is nearly 45 minutes, where my build time on my current system is about 15 minutes, max. Since I work on a team, and we make regular commits, having a 45 minute turnaround is not ideal. When I looked at the logs of my Xcode Cloud project, I saw a lot "x86_64" stuff in there, which led me to believe that Xcode Cloud is still building on Intel machines. Additionally, I run tests on my builds. The build time alone (before running tests) was almost 20 minutes. The 15-minute time I cited with my current CI/CD included build time & tests running. So, a whole cycle finishes on my current setup before tests are even run. I noticed that there was a bunch of x86_64 in the logs, which made me think that Xcode Cloud is still using Intel. Is this true? I've just gotten really used to faster build times, and I can't move onto a system like this, where the times are so drastically different. Like, I wouldn't mind build time that would add only a few more minutes to what I have now. But going from 15 -> 45 minutes is a real problem.

Unable to download iOS 26 Beta 5 Simulator
Hello, I'm checking to see if anyone else is experiencing an issue downloading the latest beta simulator. When I try to download the iOS 26 beta 5 simulator in Xcode, the download fails instantly. There is no progress, just an immediate error with no message other than the code itself: DVTDownloadableErrorDomain Code: 41. I've already restarted both Xcode and the Mac multiple times. I have also tried downloading on different networks to rule out a firewall issue.

Enrolling, LLC Disregarded company (Non- Us Resident)
Hi There, I´m From Spain with an LLC Company in the USA. Is a Disregarded company, the problem is that when I try to set up the paid apps agreement, Apple display the form W-9 instead of Form W8-BEN (that is for non-us resident) My question is... is this right? Under the name of my company, appear an option that ask me ... "Who is the Beneficial Owner? " You can choose between : Individual, Limited Liability - Disregarded Entity, Limited Liability - Partnership, Other... I choose Limited Liability - Disregarded Entity I m not sure if the form W-9 is the right for me because my other online business is about selling books on amazon and there the form that I m using is W8-BEN

Anyone noticed #Playgrounds issue with Xcode 26 beta 4?
I'm getting following message when launching #Playgrounds canvas with Xcode 26 beta 4. Here are things I've tried: Reinstall Xcode Reinstall components Removed derived data Run Disk Utility to fix permissions Tried to change Default Actor Isolation, Approachable Concurrency Changed around settings on Schemes: Run: Options and Diagnostics Created brand new project with default settings. Filed FB19003005 in Feedback Assistant. I'm surprised to see that I didn't see any posts on this during my search. So this could be isolated matter just to me.

Shared dependencies between test and production code creates library duplication
When test support code relies on production code, a diamond can occur. If this occurs across packages, it can lead to duplicated symbols and incorrect behavior at runtime despite no warnings at build time. This only occurs in Xcode and top-level application testing. This doesn't occur when the code being tested is in a separate package. I'm trying to understand how to correctly manage shared test support code which needs to access production code, or if this is the correct way and it is an Xcode bug. For a minimized example project, see https://github.com/rnapier/SupportCode. The setup includes three packages: Dependencies, which manages all the dependencies for the app and tests; Core which contains core logic and test support; and Feature, which relies on Core an contains feature-related logic and test support. Building this system causes Core.framework to show up three times in DerivedData: ./App.app/PlugIns/AppTests.xctest/Frameworks/Core_59974D35D_PackageProduct.framework ./App.app/Frameworks/Core_59974D35D_PackageProduct.framework ./PackageFrameworks/Core_59974D35D_PackageProduct.framework When unit tests are run, there is a collision on the symbol for Keychain: objc[48914]: Class _TtC8Keychain8Keychain is implemented in both /Users/ornapier/Library/Developer/Xcode/DerivedData/App-grdjljgevqofhqgflgtrqvhvbtej/Build/Products/Debug-iphonesimulator/PackageFrameworks/Core_59974D35D_PackageProduct.framework/Core_59974D35D_PackageProduct (0x100a98118) and /Users/ornapier/Library/Developer/CoreSimulator/Devices/216C441E-4AE5-45EC-8E52-FA42D8562365/data/Containers/Bundle/Application/7197F2F2-EB26-42FF-B7DB-67116159897D/App.app/PlugIns/AppTests.xctest/AppTests (0x1011002c0). One of the two will be used. Which one is undefined. This is not a benign warning. There are two distinct copies of _TtC8Keychain8Keychain and test cases will access one and the app will access a different one. This leads to mismatches when accessing static instances such as .shared. I believe this dependency graph should work, and it does work as long as the top-level testing system is a Swift module. But if it is the application, it builds successfully, but behaves incorrectly in subtle ways.

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.

Xcode 16.0 iOS 12 support
We are preparing builds using Xcode 16.0 given we have a large set of users on iOS 12. Now we have doubts wether we will run into issues if we ship using it (even if it compiles, archives and uploads successfully) given the table columns and content has changed since the last time we checked this table: https://developer.apple.com/support/xcode/. 1- Is the Deployment Targets range for Xcode 16 value correct for iOS? (On the 24th of February it had iOS 12-18, now it has iOS 15-18) 2- Are we OK to ship for iOS 12 using xcode 16.3? Thanks, Joao Garcia

XCode 16.2 - error: unable to open dependencies file
Hello, I am encountering "unable to open dependencies file" error in XCode that started after updating to Xcode version 16.2 and macOS version 15.2. The error message I receive is as follows: error: unable to open dependencies file (/Users/user/Library/Developer/Xcode/DerivedData/MyProject-cwpcmnebzjpgkzcuoauxlaeiqrsg/Build/Intermediates.noindex/MyProject.build/Debug-iphoneos/MyProject.build/Objects-normal/arm64/MyProject-master.d) (in target 'MyProject' from project 'MyProject') This problem didn’t occur with XCode 16.1; the project was building successfully before the update. Now, even reverting to XCode 16.1 doesn’t resolve the issue anymore. Here’s what I’ve tried so far without success: Switched the compilation mode to “Whole Module” Cleaned the build folder Cleared Derived Data Thank you in advance for any suggestions!

How are Assets removed?
Hello, I'm trying to figure out the behavior of AssetPackManager.shared.remove(assetPackWithID: ). I'm working with MapKit tiles and currently working on trying projecting them correctly which involves serving the AssetPack locally, downloading, checking alignment, and then deleting and changing. My question is that remove(assetPackWithID: ) completes successfully and the asset pack is removed. This is confirmed by trying to remove the AssetPack again which throws an error. However, the asset is still appearing on MapKit after the removal. This is a bit odd as this persists not only with force killing, but also restarting the device. Please advise on how to properly remove an AssetPack. Thank you iPhone 15 Pro Max (iOS 26.0.1) iPhone 17 Pro Max (iOS 26.0.1)
