XCode26 new Standard C++ Library breaks Qt 6

[artwaw]

With macOS update I noticed several issues, mainly:

In included file: 'type_traits' file not found
qglobal.h:13:12: error occurred here

In template: no type named 'parameter_type' in 'QArrayDataPointer<QString>'
qlist.h:106:28: error occurred here

and so on.
I gather this has to do with a Standard Library changes being rolled out as described in the Apple documentation here: https://developer.apple.com/documentation/xcode-release-notes/xcode-26-release-notes#C++-Standard-Library

Does anyone have any immediate solution or idea when this would be remediated?

Many thanks in advance,
Artur

Solution: some paths in Qt needed updating in build configuration - from macOS15.5.sdk to macOS26.sdk.
