Interface Builder - Xcode 26.4 - Changing Between Attributes Inspector, File Inspector, Etc. Is Now A Pop Up Button?

In Interface Builder there use to be a segmented control to switch Inspectors. It's been this way forever. I could switch from:

File Inspector

Attributes Inspector

Size Inspector

Etc...

Now in Xcode 26.4, it is this clunky pop up button? What? I thought Apple didn't like Interface Builder anymore so I'm surprised they are even touching it.

This part of a SwiftUI rewrite or just bad vibes?
