Having tried several times to engage with the community on StackExchange (various sites) I am unhappy with the exchanges in knowledge ... 

It appears to me that the moderators do not play nicely with new community members. 

I explained I was getting this message in Xcode 15:

"Requesting visual style in an implementation that has disabled it, returning nil. Behavior of caller is undefined."

This question was rejected by the Ask Different (StackOverflow site).  And the moderator there trying to be helpful - sent it over to the StackExchange (yet another site) - where the moderator there rejected it and summarily closed the question.

This started a behind-the-curtain discussion about the proper process of "migrating" a question and all kinds of pedantic terms between the site moderators.

All this leaves the poor consumers trying to contribute to the sites (the OP in their terms) feeling very rejected and unappreciated.   I'd broken the rules of "exchange", as if by merely asking.  Not very compassionate human interaction - giving us poor computer developers the reputation - we deserve.

I filed an Apple Feedback report about the Error message.  Then got a request to prove it was an Apple message.  So I learned you can get "meta" data about a Xcode message.  And it showed that the message was from UIKit.

Maybe with the call site identified - Apple engineers can track down why my App is emitting the message.  I'm not using UIKit - it's a SwiftUI app.  No calls to [UlNavigationBar _currentVisua|Style].
