Generating an Xcode project is supported, but building generated Xcode targets, which is what you appear to be attempting, is not. This is precisely why --xcode generates projects but does not build anything. If you want to build in Xcode, you need an external build system. See GettingStarted.md#using-ninja-with-xcode.

I see, this xcodeproj is used to debug already compiled swift-fronted, I need to manually select the corresponding binary file.

Another question, I can't find any Macro related targets in the generated xcodeproj, do you know how to debug Macro or where is the corresponding wiki? @AnthonyLatsis

Closing this since build-script support for Xcode project generation is deprecated and soon to be removed (#79320), you should use utils/generate-xcode instead, see here for more info
