Kind of a long way around the barn.

If I needed to to have multiple buttons and each one needed to present a different sheet, and if I didn’t want all of the boilerplate I’d just make a view for that.

struct ButtonSheetView<Content:View>: View {
    let title: String
    let content: () -> Content
    @State private var presentSheet = false
    init(_ title: String, _ content: @escaping () -> Content) {
        self.title = title
        self.content = content
    }
    var body: some View {
        return Button(title) {
            self.presentSheet = true
        }
        .sheet(isPresented: $presentSheet) {
            self.content()
        }
    }
}

With usage like..

   ButtonSheetView("Test Button 1") {
        Text("This is a test!")
    }
    ButtonSheetView("Test Button 2") {
        Text("This is another test!")
    }

Each button has its own presentation state and each button has its own sheet, and using them is just like using a NavigationLink.

No fuss, no muss.

Remember that SwiftUI’s primary emphasis is on decomposition, and making custom views carries little to performance penalties.
