-Xcode 26 no longer bundles the Metal toolchain. Some ports, at least {{{qt6-qtwebengine}}}, do require it and will thus fail to build. The solution is to install the toolchain separately using {{{xcodebuild -downloadComponent MetalToolchain}}}, although that doesn't work out-of-the-box at least with XCode 26.0.1 and MacPorts 2.11.5.

+Xcode 26 no longer bundles the Metal toolchain. Some ports, at least {{{qt6-qtwebengine}}}, do require it and will thus fail to build. The solution is to ensure that MacPorts has been updated to 2.11.6, and to install the Metal toolchain separately:
 
-on `x86_64` only:
 {{{
-diskutil eject $(xcodebuild -showComponent MetalToolchain | sed -E -n -e 's/^Toolchain Search Path: (.*)$/\1/p')
+sudo port selfupdate
+xcodebuild -downloadComponent MetalToolchain

+on x86_64 only—note that this command may show a “Usage:” line, which is fine:
