Xcode Source Control pull/push hangs indefinitely, terminal Git works normally After Tahoe 26.3 (25D125) Update
Device Details: MBP M2 Pro AND MBP M3 Pro macOS 26.3 (25D125) Xcode Version 26.3, 26.2, 26.1 (I reinstalled all 3 of these after the macOS update) BUG: Xcode hangs indefinitely when performing Source Control operations (Pull or Push) on a Git repository that uses SSH authentication. The same repository works correctly when performing the equivalent Git operations from the Terminal using the Git CLI. The issue appears to be specific to Xcode’s internal Source Control integration. When the operation is triggered from Xcode, the UI shows a spinning progress indicator and never completes. Terminal Git commands (git fetch, git pull, git push) complete normally using the same SSH key and repository. A hang sample taken during the issue shows the Xcode main thread blocked in Source Control authentication and fingerprint handling code paths, including: IDESourceControlUIHandler IDESourceControlFingerprintManager handleAuthenticationFailure showFingerprintAlertOnWindow This

Xcode 26.3 Claude Agent — 401 Invalid Bearer Token on Intel Mac (FB22141224)
I've been investigating a persistent 401 Invalid Bearer Token error with Claude Agent in Xcode 26.3 on an Intel Core i9 Mac and wanted to share my findings here in case others are affected. ENVIRONMENT Hardware: Intel Core i9 (x86_64) Xcode: 26.3 (17C529) macOS: 26.3 (25D125) THE ISSUE Claude Agent fails with Failed to authenticate. API Error: 401 - Invalid bearer token on every prompt, despite the account showing as Signed In under Settings → Intelligence. The error persists after signing out and back in, and the token is confirmed valid and unexpired in Keychain. WHAT WORKS Claude Code in Terminal works perfectly on the same machine with the same credentials The basic Claude Sonnet 4.5 coding assistant in Xcode works fine Only Claude Agent is affected ROOT CAUSE HYPOTHESIS Xcode appears to be installing an ARM64 Claude binary on Intel Macs silently, with no warning or fallback. This binary likely fails to execute on x86_64 hardware and that failure is being misreported up

Reply to User crash report contains ??? instead of my app's symbols and no binary image base address
Thanks. I wasn't sure what I should use as the load address for the atos command. I used the start address of the __TEXT segment, but I just got the crash address back: % atos -arch x86_64 -o ~/Library/Developer/Xcode/Archives/2026-02-03/MyApp 03.02.2026, 13.48.xcarchive/dSYMs/MyApp.app.dSYM/Contents/Resources/DWARF/MyApp -l 0x10462e000 0x10844eb40 0x10844eb40 Although notice that the range of __TEXT 10462e000-1048c8000 doesn't even contain the crash address 0x10844eb40. Unless I'm doing something wrong, it looks to me like the crash is out of my control and I can't really do anything about it, which like you said is kind of confirmed by the weird crash report.

Cannot create new CloudKit container after deleting all containers - need help
I accidentally deleted all CloudKit containers from the CloudKit Database console, and now I'm unable to create new containers. Both the CloudKit Console website and Xcode are not allowing me to create any new containers. Is there a way to restore the deleted containers? How can I create a new CloudKit container if the console website is not responding? Thank you.

Reply to Unable to install Metal toolchain through Xcode Cloud
removing the script didn't fix for me. the script had been holding it together till now, but something changed recently. Ok — since this sounds like a recent change, it would be helpful for us to get a bug report from you so we can look into this further. It would be helpful if you could detail the exact configuration you've set for this build environment (macOS version and Xcode versions), and a link to a specific build. Once that's filed, please post the FB number here so I can locate your report. — Ed Ford,  DTS Engineer

Reply to New project with new AppIntent throws build error
To see what happened here, I used Xcode 26.4 beta 3 to create a new multi-platform app. I added a new file, added an import statement for App Intents, and then copied in the snippet of getting started code from the documentation. Indeed, this fails to compile. That new project's default build setting configuration is: Swift Langage Version: Swift 5 Approachable Concurrency: Yes Default Actor Isolation: MainActor To allow this to compile, I change the Default Actor Isolation build setting to nonisolated instead. This is worth a bug report — please use Feedback Assistant to report it, and post the FB number here so I can follow up on it. — Ed Ford,  DTS Engineer

How to upload large videos with PHAssetResourceUploadJobChangeRequest?
I'm implementing a PHBackgroundResourceUploadExtension to back up photos and videos from the user's library to our cloud storage service. Our existing upload infrastructure uses chunked uploads for large files (splitting videos into smaller byte ranges and uploading each chunk separately). This approach: Allows resumable uploads if interrupted Stays within server-side request size limits Provides granular progress tracking Looking at the PHAssetResourceUploadJobChangeRequest.createJob(destination:resource:) API, I don't see a way to specify byte ranges or create multiple jobs for chunks of the same resource. Questions: Does the system handle large files (1GB+) automatically under the hood, or is there a recommended maximum file size for a single upload job? Is there a supported pattern for chunked/resumable uploads, or should the destination URL endpoint handle the entire file in one request? If our server requires chunked uploads (e.g., BITS protocol with CreateSession → Fragment → CloseSession), is this ext
