I was encountering a bug on my app where my View displayed in a sheet was getting initialized twice. I was initializing my ViewModel in that view, which was causing all sorts of problems with multiple network requests firing and my views not updating.
Debugger output:
init sheet
init sheet
I tracked it down to this line in my ContentView:
@Environment(\.presentationMode) var presentationRemoving that line solved my problem.
I had initially added it to workaround some other SwiftUI bug but I found a different workaround for that.
