> the new macOS Dock, the new daemon launcher, the new documentation system, package infrastructure, the new background services, the server side frameworks, the new photos picker, playgrounds are all written in Swift.
The Dock is an app, not a framework. The things you listed are not frameworks, aside from whatever you mean by "the server side frameworks", which being server-side would by definition not be in macOS.
"Framework" has a very specific meaning in the OS: a .framework bundle, providing a linkable executable and typically an API, with the system frameworks residing in /System/Library/Frameworks.

This is still false, you have nothing but anecdotal, cherry-picked evidence, the numbers from the blog posts I cited suggest otherwise, you appear to be quite ignorant, and I'm tired of arguing with you, so I'm indeed DONE here.
