I'm also seeing that TUINSRemoteViewContrroller message in a SwiftUI app when I enter data in a text field, 14.5 beta.

Sorry, it's not the buttons. I saw that message in the console when I entered text into a text field after I commented the buttons out

I'm seeing thatTUINSRemoteViewController console message in a SwiftUI project after adding two buttons to one of my windows; on Sonoma 14.5 Beta -- but since the buttons are new today, I really don't know which update it (would have) started on.
