Answer 1

The whole issue is very easy to fix just add self.networkManager @ EarthQuakeList.swift

.sheet(isPresented: $showEditPage) { 
                            return EditPage().environmentObject(self.networkManager)

I got the reason and inspired from article: https://github.com/peterfriese/Swift-EnvironmentObject-Demo
