I just start project 10 - Time Buddy in Hacking With macOS (swiftUI edition)

At the begin of this project we have to set our application is UIAgent to yes to remove icon and application menu. It doesn't work when I follow the book instruction : editing TimeBuddy/Info/Add "Application is agent (UIElement) = YES

I resolve the problem on visiting github final project on github. I saw an Info.plist thaht containt this : {"LSUIElement":true}

I copy this in my own project and modify Build Setting / Packaging to use my Info.plist file

Now it's works as expected but I need more information and I think the book need an update
