`executable` in Run Action not setting properly

I have configuration with other app added to project byprojectReferences

projectReferences:
  xyz:
    path: ../Modules/xyz/xyz.xcodeproj

and I set

schemes:
  xyz:
    build:
      targets:
        xyz/xyz: all
    run:
      executable: "xyz/xyz"

According to the documentation:

 executable: "xyz"

or

 executable: "xyz.app"

Not working too

And in project I have settings like this after xcodegen generate

Executable is missing 👎 How can I add this properly?
