I just install xcode 26.0.1 throungh app store, but when i 'xcodebuild -downloadComponent MetalToolchain', i get wrong Metal Toolchain 17A324, which is the wrong version. The correct version is 17A5241e i think. This issue i saw 26.1 release has fixed, https://developer.apple.com/documentation/xcode-release-notes/xcode-26_1-release-notes. How can i get update?
Unable to compile Core Image filter on Xcode 26 due to missing Metal toolchain
The 17A324 Metal Toolchain is the correct version for Xcode 26 and Xcode 26.0.1. 17A5241e was a version during the beta period. Are you running into any specific issues when using 17A324, or was it just the version numbers that you were unsure about?

I encounter the same issue, Xcode Version 26.0.1 (17A400); Metal Toolchain 26.0.1(17A324). this issue reappear after I restart my computer. I think there is also a bug not fix by Xcode26
Hi!
Did you install the toolchain after downloading it?
The easiest way to manage Xcode components is via the Settings > Component panel.
@Product Manager I installed the Metal Toolchain by Settings > Component panel but it's not work, the component appear in Xcode component panel, but compile error because miss Metal Toolchain
I encountered the same problem even I used the Xcode26 Xcode26.0.1 Xcode26.1(https://developer.apple.com/forums/thread/805547)
after two days try I fixed this problem by followed the methods in this article(https://medium.com/@sergey-pekar/how-to-fix-annoying-xcode-26-not-building-swiftui-previews-error-cannot-execute-tool-metal-due-49564e20357c)
I think there is still has a bug for install Metal Toolchain at least for those migrated from Xcode26 Beta
