Reply to Missing DirectX Calls for Tearing and Depth Bound Test in D3DMetal and GPTK 3
Thanks for the detailed report and for filing FB22330617. A couple of clarifications on the specific items: For D3D12_FEATURE_D3D12_OPTIONS2.DepthBoundsTestSupported — depth bounds testing is not supported on all Apple Silicon hardware. If your hardware doesn't support it, D3DMetal is returning the correct value. Your game should have a code path that handles hardware where this feature isn't available. For IDXGIOutput6::GetDesc1().ColorSpace returning SDR on an HDR-capable display — can you clarify whether you're seeing this on the built-in display, an external display, or both? That distinction affects the diagnosis. For debugging the water rendering issue, Xcode's GPU frame capture is the recommended approach. Capture a frame while the issue is visible and inspect the draw calls, shader inputs, and render targets to identify where the geometry or shader output diverges from what you expect. Given that you're seeing the water placed at an extreme Y position, the frame capture should help narrow dow

Cannot Export Mac app from Xcode 26.4
Took app and selected Archive. Selected Direct Distribution. Process completed. I selected export app. Could not elect the app to export since it was greyed out. Queried on both google and Claudie. Followed all the instructions and there is still no joy. Worked fine yesterday.

Xcode 26.4.1 simulator 16.0 bugs.
I cannot get a Jiggle on an iPhone 15 using the iOS 17.0 simulator. I cannot drag icons or widget around, only have the option to remove them. On both the iOS 17.0 and iOS 26.4 (running on an iPhone 17 simulator) There is nothing in my drawer for adding a widget, no system widgets either (attached screenshots). Just the Search Widgets bar that does have widgets in it. The system widgets are in the screen to the left of the home screen. I can put widgets I find through the search on the home screen. Although on the iOS 17 emulator no jiggle means no repositioning. May computer is running MacOS 25.4.1 and the latest versions of everything. I have asked AI, I have tried wipes, locking, unlocking, reseting, re-installing, light mode/ dark mode to refresh any cached images, trying to drag system widgets from the left side of the home screen, a widget kit development mode option in settings > developer on the iPhone and something using the command line for chronosd that never worked. The iPhone 17 simulator has

Reply to SystemLanguageModel.Adapter leaks ~100MB of irrecoverable APFS disk space per call
To clarify, this isn't a memory leak, it's an issue with not de-duplicating or evicting copied model weights from a SIP-protected disk space. I'm also not sure the bug is CLI-specific. I definitely observed it with my CLI tool, Junco,, but I have another SwiftUI application where I'm observing the issue as well. Simply running the app from XCode copies the weights & metadata to the location above, and I've only been able to delete the accumulated ~104GB (645 model clones) through Recovery Mode.

Reply to Xcode Metal Capture crash when using MTLSamplerState
Thanks for the detailed repro project and for filing FB22031701. Your fix is correct — setting supportArgumentBuffers = true on the MTLSamplerDescriptor is required when the sampler will be encoded into an argument buffer. Without that flag, the sampler isn't guaranteed to work in that context. The fact that it rendered correctly at runtime without the flag was lenient behavior rather than something to rely on. Regarding the capture crash: we've had trouble reproducing this with your repro project on more recent tools, so the crash may already be resolved. If you're still seeing it with the latest Xcode, please update FB22031701 with the version you're using and a fresh GPU trace, and we'll take another look.

Reply to SceneKit is now deprecated - when it will be removed?
RealityKit is not currently available on watchOS. In the Xcode 26 SDK, RealityKit ships for iOS, macOS, tvOS, and visionOS — but not watchOS. SceneKit remains the only 3D framework on that platform. The soft-deprecation terms apply equally to SceneKit on watchOS: your apps will continue to work, and there is no date for hard deprecation. If RealityKit on watchOS is important to your work, please file a request through Feedback Assistant. That's the best way to signal demand to the teams involved.

Reply to HCE not working in Testflight Builds
TestFlight distribution and testers have the same requirements as your end users who would be downloading your app from the App Store. This means the testers will have to be: physically be in the EEA logged on to their phones with an iCloud account based in the EEA As explained in the documentation HCE-based contactless NFC transactions for apps in the European Economic Area (EEA), if you have testers outside the EEA, you cannot use TestFlight builds. Testing requirements Apple has developed a solution which allows HCE Developers to develop and test HCE Payment Apps outside the EEA. The new solution allows development and testing on a device through known and well-used means such as Xcode and provisioning of profiles used for testing on devices within a developer’s organization. Developers will be able to have up to 100 test devices outside the EEA. To test HCE-based contactless transactions, you’ll need to test with an iPhone and NFC hardware.

Claude Agent Error: API Error (claude-opus-4-6): 400 The provided model identifier is invalid.
I have been using Claude Agent with an Anthropic API Key in Xcode 26.3 for a while now. Recently it stopped working, giving me this error message: API Error (claude-opus-4-6): 400 The provided model identifier is invalid. I have tried relaunching Xcode, signing out and signing back in, changing the default model in the Claude configuration UI and nothing works. I've had to fall back on using the Claude Code CLI and the MCP server, which loses a lot of the value of Xcode/Claude integration.

View Navigation Title Disappears on watchOS Target When Built With Xcode 26+
I have a SwiftUI view in a watch companion app, and when I build my app with Xcode 26.2 or 26.3, the navigation title on a presented screen disappears after the watch screen goes dark. So, the navigation title is only visible when the screen is first presented and not again after the watch screen goes dark, for example when the user lowers their arm. Please see the screenshots for a better understanding. Notice that the Bench Press text is not visible in the third image. Also, I’ve confirmed that this does not happen when the app is built with Xcode 16.4. First Image (initial presentation of the screen): Second Image (watch screen goes dark): Third Image (watch screen goes back on, title missing): Although I've confirmed that this is related to Xcode versioning, and it happens on multiple screens, here is the redacted version of this SwiftUI view that is shown in the screenshots, in case it helps: var body: some View { NavigationStack(path: $viewModel.pushedViews) { TabView(selectio

Unable to upload build – “No App Store Connect access for the team
Hello, I am experiencing an issue when trying to upload my app to App Store Connect via Xcode. I am the Account Holder and Admin of my Apple Developer account, and I can successfully log in to App Store Connect. My account appears correctly under “Users and Access” with full permissions.

App Store Distribution – Minimum Deployment Targets (iOS, macOS, tvOS, watchOS) with XCode 26
Hello Team, We’ve confirmed Apple’s current minimum OS requirements for Xcode 26: iOS 15 – 26 iPadOS 15 – 26 tvOS 15 – 26 watchOS 8 – 26 visionOS 1 – 26 macOS 11 – 26 Are we correct in understanding that any builds targeting below these versions are no longer accepted by the App Store and may fail to launch for users on older systems? Like this https://developer.apple.com/forums/thread/821370?answerId=882822022#882822022 For Steam macOS distribution, can older macOS targets still be supported, or should we align strictly with Apple’s minimums? Thank you and best regards, Phong

HCE not working in Testflight Builds
We have enabled the Host Card Emulation (HCE) capability for our app and successfully implemented and tested the functionality during development. When running the app directly from Xcode, HCE-related flows work as expected. However, we are observing different behavior in the distributed build. In particular, the following check consistently evaluates to false: guard await CardSession.isEligible else { return } After distributing the app via TestFlight, HCE functionality is not available for external testers. The CardSession.isEligible property always returns false, even when tested on supported devices and in supported regions. We are using the same bundle identifier for both development and distribution builds, and the provisioning profiles include the required capability. Could you please clarify the following: Are there any additional entitlements, approvals, or configuration steps required for HCE to function in TestFlight or distribution builds? Are there known region, device, or account-relate
