This has been answered multiple times but never afais gives the response starting by pressing a Button to get to the next View. Adding this approach just in case someone ends up (just like me) on a Google search that has this answer as one the top links.

This approach is a combination of @State variable on the Initial View and the same variable as @Binding in the Ending View. You can always add a "Back" button on the ending View to return to the original.

struct InitialView: View {   
    @State private var isEndingViewActive = false   
    HStack {
            var body: some View {
                if isEndingViewActive {
                    EndingView(isEndingViewActive: $isEndingViewActive)
                } else {
                Button(“Going to End View”) {
                   isEndingViewActive = true
                }
            }
        }
    }
}

struct EndingView: View {    
    @Binding private var isEndingViewActive: Bool
    HStack {   
            var body: some View {
                Button(“Going Back to Initial View”) {
                isEndingViewActive = false
                }
        }
    }
}
