I’m following the text, adding to the starter/HNReader.xcodeproj
Looking for the first numbers to appear when adding .onAppear method, I find my debug output cluttered with lots of warnings (I’m on Xcode Version 13.2.1 (13C100), M1)

Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.

First thing I see is that there’s an Info.plist which I don’t have when I start a new SwiftUI project from scratch. Removing it only (thought about left overs from non SwiftUI version due to SceneDelegator class, etc.) “solves” the first warning, but keeps me from installing the app on any simulator device because a bundle identifier is missing (although one is given in the corresponding target field).
Since I’m starting again with Xcode dev after some time I wonder what’s going on and how to fix it. I can’t really work with this noise in the debug window.
Any clues?
Thanks for the help.
