Chap 10 page 190 is about adding a constraint for a size class using “Vary for Traits” command from the popup on the “Device Configuration Bar”.
However WHERE / HOW is a new constraint created for a particular size class in xCode 13.1 ???
The popup seems to have disappeared in the current xCode 13.1.
The release notes 13.1 state:
" * Interface Builder has a redesigned canvas bottom bar with popovers for changing devices and layout, and toggles for changing device appearance and orientation. (68288315)"
( See the Interface Builder section of Apple Developer Documentation )
The mentioned popup seems to have moved in the redesign…
The “+” indicator does show on the attributes inspector for trait classes and there is the “All” and “This Size Class” buttons…
Where did the popup for setting of a size class go?
