Cant get my sheet to display the right information - swift

Question

/*
I have an .onTapGesture on my MapAnnottions. If I press the MapAnnotations for the first time a
black/empty DisplayBusinessSheet will appear. I want it to display a certain type of
information. If I dismiss the sheet and press the same annotation I only get a black/empty
sheet. If I dismiss the sheet again and press another location/ MapAnnotation in my map it
displays the right information. I reallyyyyyy don't know what's happening, been stuck for solongggg, please help me <3

In iOS 14 sheet(isPresented:content:) is now created beforehand and the view is not refreshed when the $businessSheetPresented changes.
Instead of .sheet(isPresented:content:)
.sheet(isPresented: $businessSheetPresented) {
if let pressedUser = pressedUser {
DisplayBusinessSheet(user: pressedUser)
}
}
you should use .sheet(item:content:)
.sheet(item: $pressedUser) { user in
DisplayBusinessSheet(user: pressedUser)
}
Note: with the above solution you don't really need businessSheetPresented unless it's used in some other place apart from triggering the sheet.
