你想达到这个目标吗？

struct ProfileButton: View {

    @State var showingProfile = false // Could be also Binding or else

    var body: some View {

        Button(action: {
            self.showingProfile.toggle()
        }) {
            Text("blubb")
            Image(systemName: "person.crop.circle")
                .imageScale(.large)
                .accessibility(label: Text("User Profile"))
                .padding()
        }
    }
}

struct ContentView: View {

    let profileButton = ProfileButton(showingProfile: true)

    var body: some View {
        NavigationView {
            Text("aah")
            .navigationBarTitle("Test")
            .navigationBarItems(trailing: Image(systemName: "person.crop.circle"))
        }

    }
}
