When I want to build my project I do not want to press a play button.

Could there be a more universal idiom in the world of IDEs?
He said BUILD, not RUN. A Play button is to build and RUN the project. I agree with his objection: There's no Build button in the UI.
And even worse is the width of the combined drop-down list for configurations. There's a vast expanse of empty space in the (now non-customizable) toolbar, and they made this control SMALLER. The information it should be providing is cut off in all cases, even with short project names. I try to be sympathetic to the Xcode team's tasks, but this is idiotic.
But then they end up doing things like throwing out a working documentation viewer and replacing it with a new design that doesn't work.
