SwiftUI Scrumdinger Tutorial - Data Persistence Locally on macOS?

Hello, I'm having some issues with this tutorial regarding data persistence when running locally on my Mac Mini M1 in the simulator. I built my own app based on this app but the data do not save or reload. I've altered the code so that it's not reading from the DailyScrum.data, but instead from the ScrumData.data, and that seems to work (it loads nothing, which would be expected since file is empty at start). I can add values, but when I restart the app in the simulator, there are still no values. I did the search for the file on the device, and found the appropriate folder, but the data file is not there.

I downloaded the last tutorial 'completed' project and did the same thing with the original code (commenting out the #IF #DEBUG load code). Still no luck.

However, when loaded onto the iPhone, the app DOES work and the data persist. I'm a Windows developer new to iOS so I may be missing something completely - but I can't seem to get either my, or the downloaded project when running on the MacOS, to work. Is that expected behavior? The way the tutorial reads (open the terminal, type in this command to find the file) it seems like they are expecting that you are on Xcode on macOS. What exactly am I missing?

Thanks!
Hey I've been attempting to implement data persistence using this tutorial as well and have, for some reason, not been able to successfully get the data to persist on app closure (when you swipe up to force quit). I'm curious as to how you may have been able to get past this issue, if you had the same issue I did.
