Hello. I migrated yesterday two machines from OS15 to OS26 (same Ram; M1Max chip). On the first one, a MBP, everything is allright, and my old Metal projects can compile and run, even with MacOS12 as a destination. On the second computer (MacStudio) I got a compile error: cannot execute tool 'metal' due to missing Metal Toolchain; use: xcodebuild -downloadComponent MetalToolchain. I spent hours on many forums and tried all proposed solutions and still get the same error. Any idea? Thanks

I have been using Xcode Version 26.1.1 on macOS Tahoe Version 26.1. In VIM mode, whenever I quickly tap d twice, to delete the complete line, most of the time Xcode crashes. Is anyone else facing this issue? Should I move to any older version of Xcode or any other solve for this?

The latest version of Xcode available on: https://developer.apple.com/download/applications/ is Xcode 26.2 build 17C52. It was released today, December 12, 2025. However, uploads are failing with error: Validation failed. This bundle is invalid. Apple is not currently accepting applications built with this version of Xcode. I have verified my Xcode is not beta: I think that at least the non-release candidate, latest version of Xcode should be allowed to submit apps.

Hello, We are trying to use the new Background Upload Extension to improve uploads of assets (Photos, Live Photos, Videos) in the background in our application. 1 - We implemented the code to upload still images. We would like to do the same for Live Photos but we are not sure how to proceed since a Live Photo is composed of 2 resources that we would like to upload in the same job so that we keep the association between the 2 resources. Steps: A Live Photo is captured on the device. Our application is notified for new content in the Photo Library and the asset is queued for upload by our application. The system calls the background upload extension and the Live Photo is prepared for upload but we can schedule a job only for one resource (still photo or paired video) so we can not upload both resources in a single job. 2 - Is there a way to synchronise the application and the extension so that the application would not process the same data or execute the same requests than the extension. For example: our appl
