Thank you Claude, I think I understand, but remember I am 40 years out of date. I have used something called "Playground" and it seems to work there. I am not sure what "Playground" is maybe I need to watch more of the tutorial.

I have the same issue. I have also tried the advice above, and the simulator I added that way does not appear on the list of devices on the storyboard but does appear as a simulator on the ViewController. So has anyone solved this issue?

I have absolutely no idea what I did to turn them off, but I have followed your advice to no avail. I still hasver no error messages.

I can't believe this, I shutdown my iMac overnight and now the error messages are back???????

Thank you so much darkpaw for your extremely well-explained and thorough answer from which I learned about what a Spacer() is, I am an Idiot, I thought I had tried that but obviously not.

Hi Quinn, As a diabetic, I am trying to develop an App that will help monitor my Blood Glucose and compare it with my food intake, and my physical activity. I am using SwiftData and Cloudkit to share the data across all my devices. I want the App to have a background Image and a logo. and the View Controllers work differently on a Mac than on an iPad/iPhone.
